PI7C8148ANJE - 2-Port 32-Bit 66MHz PCI Bridge | Diodes
Diodes Incorporated PI7C8148ANJE is a 2-port PCI-to-PCI bridge interface IC built for 32-bit PCI systems operating at up to 66 MHz. The device is supplied in a 160-LFBGA package measuring 15 x 15 mm, with tray mounting and a 3 V to 3.6 V operating supply range. A PCI bridge is an interface integrated circuit that connects two PCI bus segments and allows devices on one segment to communicate with devices on another. In the PCI hierarchy, the PI7C8148ANJE sits between a host or upstream PCI bus and a downstream PCI segment. Its 32-bit, 66 MHz capability makes it relevant to legacy PCI expansion, embedded system integration, industrial control, and legacy industrial computing platforms where a single bus cannot directly reach all peripherals. The main verified device characteristics are the 2-port PCI-to-PCI architecture, 32-bit PCI data width, 66 MHz operating frequency, 3 V to 3.6 V supply range, and 160-LFBGA (15 x 15 mm) package. These specifications define the electrical and mechanical envelope for the component. The package uses surface-mount LFBGA construction, requiring a PCB land pattern with controlled escape routing and careful via placement beneath the device. The bridge is intended to provide transparent PCI bus segmentation where upstream and downstream agents must share a PCI bus. Using a bridge allows more physical distance between bus loads than a single shared segment may support, while preserving protocol handling within the PCI interface domain. Designers should confirm arbitration, interrupt routing, clocking, and downstream-bus loading against the manufacturer datasheet before finalizing a system. Typical uses include legacy PCI industrial controllers, PCI-to-PCI embedded adapters, test equipment, communication systems, and expansion systems that must retain a 32-bit 66 MHz PCI interface. The 160-LFBGA package is most appropriate for multilayer PCB designs where fine-pitch routing and adequate ground-plane continuity can be implemented. The main design consideration is package complexity. A 160-LFBGA footprint is more demanding than a leaded package for assembly, inspection, and repair, so designers should provide adequate via-in-pad or via fanout options, a continuous reference plane, and process controls for solder bridging. The 3 V to 3.6 V supply requirement also means the bridge must be integrated with a compatible 3.3 V power rail and correctly decoupled at its supply pins. This page consolidates the verified distributor and manufacturer-linked information for PI7C8148ANJE, provides practical packaging and PCB guidance, and distinguishes confirmed parameters from information that must be confirmed in the manufacturer datasheet before production release.
PI7C8148BNJE - 32-Bit PCI-to-PCI Bridge | Diodes Incorporated
The Diodes Incorporated PI7C8148BNJE is a PCI-to-PCI bridge interface controller for 32-bit, 66 MHz PCI bus systems, supplied in a 160-LFBGA (15x15 mm) package. It is designed to bridge separate PCI bus segments and operates from a 3.3 V supply, with a stated operating range of 3 V to 3.6 V. The device is categorized as a line and bus controller within the interface IC market, providing a standardized way to connect PCI-compatible devices or subsystems across a PCI-to-PCI link. A PCI bridge is a type of interface controller that connects two PCI bus domains while preserving the electrical and protocol behavior expected by PCI peripherals. The PI7C8148BNJE is intended for embedded systems, industrial equipment, communications platforms, and test systems that require a dedicated bridge rather than a direct connection between PCI devices. Its 32-bit bus width and 66 MHz operating frequency match the PCI bus-generation requirements identified in the verified product data. The principal electrical characteristics available from the verified sources are a 3.3 V operating supply, a 3 V to 3.6 V supply-voltage range, and a 0 °C to 85 °C commercial operating-temperature range. The 160-LFBGA package provides a compact surface-mount implementation for space-constrained board designs. The verified distributor descriptions identify the part as a two-port PCI-to-PCI bridge interface, while the available technical listing identifies it as a 32-bit, 66 MHz PCI bridge chip. Because the product data does not include a complete manufacturer electrical table, detailed specifications such as absolute maximum ratings, quiescent current, propagation delay, PCI signal-level thresholds, and package thermal resistance are recorded as data-needed rather than estimated. The available data also identifies the part as active in one distributor listing and confirms distribution through multiple channels, including DigiKey, Mouser, LCSC, and Octopart. Price and lead-time information should therefore be checked against the current distributor offer for the exact MPN. Typical application considerations include host-adapter boards, embedded PCI expansion systems, industrial control equipment, and PCI-compatible communication or test platforms. The key design issue is ensuring that the bridge, power supply, clocking, and downstream PCI devices comply with the system’s PCI timing, impedance, and power-budget requirements. A compact 160-LFBGA footprint also demands careful PCB layout, thermal analysis, and assembly-process control. This page combines the verified supplier specifications, package and pricing references, cross-reference candidates, and practical engineering considerations to provide a concise purchasing and design reference for the PI7C8148BNJE.
PI7C8150AMAE - 2-Port 66MHz PCI Bridge | Diodes Incorporated
Diodes Incorporated PI7C8150AMAE is a 2-port PCI-to-PCI bridge controller operating at up to 66 MHz and supplied from 3.3 V. The device is packaged in a 208-pin FQFP measuring 28 mm by 28 mm. According to the verified distributor and technical-source data, it is classified as a PCI interface bridge and line or bus controller, making it suitable for systems that need to bridge two PCI bus segments while preserving legacy peripheral compatibility. A PCI bridge is an interface IC that connects two Peripheral Component Interconnect bus segments and manages transaction flow between host and peripheral devices. Within the broader semiconductor hierarchy, this component is a PCI interface IC, a bus controller, and an integrated circuit intended for computer expansion and embedded legacy I/O systems. The PI7C8150AMAE specifically combines a 2-port topology with a 66 MHz maximum PCI clock and a 3.3 V supply requirement. The principal verified characteristics are a 2-port PCI-to-PCI configuration, a 66 MHz maximum operating clock, a 3.3 V supply voltage, and a commercial operating-temperature range of 0°C to 85°C. These specifications make the bridge relevant to PCI industrial controllers, embedded computer platforms, communication equipment, test systems, and industrial adapters that still rely on parallel PCI infrastructure. Its large FQFP footprint provides the physical pin count expected for two independently bridged PCI interfaces. The PI7C8150AMAE is a legacy interface device rather than a general-purpose processor, so its design value depends on maintaining a compatible host bus, connector arrangement, termination network, clocking scheme, and software configuration. A bridge installation must account for the 3.3 V supply requirement, the 0°C to 85°C operating range, and the pin-intensive 208-pin FQFP layout. The verified source snippets do not provide the complete electrical timing tables, maximum current ratings, internal divider values, or the complete pin assignment. Typical deployment uses place the bridge between a primary PCI bus and a secondary PCI segment. Because the component is a two-port bridge, it can support bus-segment connectivity without the external discrete buffering normally required when extending a PCI topology. Integration can reduce board complexity, although the FQFP package requires careful escape routing, ground-plane continuity, and compliant power distribution. The 66 MHz clock limit also defines the performance envelope for attached PCI peripherals. Designers should verify all timing, electrical, reset, clock, and pin-level requirements against the manufacturer datasheet before layout or procurement. In particular, verify PCI specification support, bus-width details, input and output current limits, enable sequencing, peripheral connect/disconnect behavior, and the exact meaning of all 208 pins. Distributor availability and pricing should also be checked because the visible search data does not establish a uniform quantity-price schedule for this exact MPN. This page consolidates verified distributor and manufacturer-source references, separates known specifications from missing technical fields, and identifies a same-family base-frequency alternative for engineers who need a drop-in comparison. The data also records the package, operating conditions, sourcing links, and the technical checks required for a safe PCI-bus integration rather than inferring unverified timing or pin values.
PI7C8150ANDE - 66MHz 2-Port PCI Bridge | Diodes Incorporated
The Diodes Incorporated PI7C8150ANDE is a specialized PCI-to-PCI bridge interface IC designed for extending or bridging PCI bus systems. The device operates at a maximum clock frequency of 66 MHz, supports two PCI ports, and is supplied in a 256-pin PBGA package measuring 17 x 17 mm. It is intended for legacy PCI expansion, industrial computer, embedded controller, and test-system architectures where an additional PCI-to-PCI interface is required. A PCI bridge is an interface-controller device that connects two PCI bus segments and helps manage transaction translation, arbitration, and the electrical protocol requirements of the Peripheral Component Interconnect bus. In the system hierarchy, the PI7C8150ANDE is a bus controller and interface IC, which belongs to the broader semiconductor and computer-interface ecosystem. The verified product information identifies it as a two-port PCI bridge operating at 66 MHz. The PI7C8150ANDE uses a 3.3 V supply according to the available specification data. The listed maximum supply voltage is 3.6 V, and the reported operating temperature range is 0 to 85 degrees C, or 32 to 185 degrees F. These figures make the component suitable for systems built around conventional 3.3 V PCI interfaces, provided the surrounding equipment remains within the specified environmental range. The 256-PBGA package provides the required dense interconnect arrangement for a high-speed, multi-signal bridge device. Because the available verified results do not provide the complete pin assignment, detailed timing tables, power-consumption values, or electrical characteristics, those parameters should be confirmed against the manufacturer datasheet before final PCB release. The package footprint, signal integrity, power-plane distribution, and PCI connector routing are especially important in a 66 MHz PCI design. Typical uses include PCI industrial motherboards, embedded PCI adapters, legacy workstation peripherals, test equipment, and systems that need a dedicated bridge between PCI host and target buses. The PI7C8150ANDE is best considered a specialized legacy-PCI solution rather than a general-purpose modern PCIe interface. For implementation, engineers should verify the exact PCI electrical requirements, I/O voltage, termination strategy, clock routing, and BGA assembly process against the datasheet. This page summarizes verified distributor and datasheet-search information, identifies the package and interface function, and highlights the data needed for a controlled hardware release.
PI7C8150BMAE - 66MHz PCI-to-PCI Bridge | Diodes Incorporated
The Diodes Incorporated PI7C8150BMAE is a 32-bit PCI-to-PCI bridge interface IC with two 32-bit PCI ports, asynchronous operation, and support for operation up to 66 MHz. It is packaged in a 208-pin FQFP measuring 28 mm by 28 mm. The device is designed to comply with PCI Local Bus Specification Revision 2.2 and provides a configurable bridge between primary and secondary PCI buses. A PCI-to-PCI bridge is an interface controller that extends a PCI local bus through a transparent transaction bridge. In the product hierarchy, this device is a bus controller, interface IC, and ultimately a semiconductor. The primary and secondary ports each operate at 32-bit width, allowing legacy PCI expansion systems, embedded modules, industrial controllers, and data-acquisition equipment to communicate across separate bus domains while preserving the electrical and transaction behavior expected from PCI Revision 2.2 systems. The verified device family supports asynchronous operation, meaning the primary and secondary interfaces do not require a shared clock. Both ports can run up to 66 MHz, while the PI7C8150B-33 family option is limited to 33 MHz. These characteristics distinguish the bridge from simpler endpoint devices: the PI7C8150BB family translates bus transactions between two PCI segments rather than terminating only one host bus. Its large 208-pin package also provides the substantial I/O and power connections required by two full 32-bit PCI interfaces. Mechanically, the MAE ordering code is associated with the 208-FQFP 28 mm by 28 mm package. The package is substantially larger than a modern low-pin-count interface IC, so its footprint imposes demanding PCB routing and assembly requirements. Exact pin names, exposed-pad connections, voltage tolerances, input thresholds, output timing, current limits, temperature ratings, and package thermal data were not included in the supplied verified records and must therefore be confirmed in the manufacturer datasheet before schematic capture or layout release. Typical applications include PCI-to-PCI expansion systems, embedded industrial control platforms, communications equipment, legacy data-acquisition chassis, and computer expansion products that require an additional bus segment. The asynchronous capability can simplify clock-domain planning when the two PCI segments do not operate in lockstep. However, system designers must still validate bus timing, termination, drive strength, isolation requirements, and power sequencing against the specific board configuration. The main design consideration is PCB complexity. Two full 32-bit PCI buses require careful point-to-point routing for address, data, control, interrupt, and clock signals, together with conservative return-path planning. Layout should minimize stubs, provide continuous reference planes, control crosstalk, and keep bypass connections close to the device. Because the verified data does not supply complete pinout or layout guidance, engineers should use the official Diodes PI7C8150B documentation rather than infer connections from third-party listings. This page consolidates the verified manufacturer description, distributor identification, package information, and product-family behavior into an engineer-oriented reference. It also distinguishes documented capabilities from missing electrical data and explains when a true pin-compatible replacement cannot be confirmed from the available cross-reference records.
PI7C8150BND - 2-Port 32-Bit PCI Bridge | Diodes Incorporated
Diodes Incorporated PI7C8150BND is an asynchronous 2-port PCI-to-PCI bridge with 32-bit primary and secondary interfaces operating up to 66 MHz, housed in a 256-pin PBGA package measuring 17 mm by 17 mm. According to the manufacturer product page, the device supports asynchronous operation and is designed for compliance with the PCI Local Bus Specification Revision 2.2. A PCI-to-PCI bridge is a semiconductor interface controller that connects two conventional Peripheral Component Interconnect bus segments. It belongs to the interface-controller hierarchy, where a PCI bridge translates and arbitrates bus transactions between a host-side primary port and a peripheral-side secondary port. This device adds no external memory or cache to the system; instead, it provides the electrical and protocol interface needed to extend a 32-bit PCI topology. The PI7C8150B family provides 32-bit primary and secondary ports capable of running to 66 MHz, while the PI7C8150B-33 version is identified as a 33 MHz variant. Other advertised characteristics include asynchronous operation and PCI Local Bus Specification Revision 2.2 support. The PI7C8150BND ordering code is supplied in the 256-pin PBGA package with a 17 mm by 17 mm body, making package compatibility a primary screening criterion when evaluating any proposed replacement. The bridge architecture is intended for systems that require a secondary PCI segment rather than a compact serial interconnect. Its two independently referenced bus interfaces support legacy PCI topology expansion, while the 32-bit data path accommodates the width used by the PCI Local Bus Specification Revision 2.2. Engineers must still account for platform-specific voltage, clocking, termination, and signal-integrity requirements when integrating the device into a complete motherboard or embedded system. Typical uses include industrial PCI expansion, data-acquisition equipment, communication appliances, test systems, and embedded controllers that retain a conventional PCI host bus. Because this is a complex 256-pin BGA device, layout requires exact ball assignment, multilayer routing, solid return planes, and careful simultaneous-transition-noise control. Firmware must also enumerate the bridge and configure the secondary bus, so replacing it requires validation beyond comparing the package and nominal clock rate. For a new design, verify the manufacturer datasheet for voltage domains, I/O standards, clock requirements, reset behavior, electrical characteristics, and the complete ball map before committing a PCB footprint. For a repair, do not assume a related order code is interchangeable: suffix changes can represent package, temperature, lead-free, or speed variations. The verified distributor listings identify the device as a PCI interface IC and provide ordering and availability information, but they do not expose enough technical data to claim unqualified pin compatibility for every related suffix. This page consolidates manufacturer and distributor findings, verified package information, family-level operating details, sourcing links, and engineering-oriented selection guidance. It separates documented facts from unresolved electrical and mechanical details, allowing engineers to narrow a replacement before performing full datasheet, firmware, and signal-integrity validation.
PI7C8150BNDE - 32-Bit 66MHz PCI Bridge | Diodes Incorporated
Diodes Incorporated PI7C8150BNDE is a 32-bit asynchronous PCI-to-PCI bridge with two ports operating up to 66 MHz, supplied in a 256-pin PBGA package measuring 17 mm by 17 mm. The device is designed to comply with PCI Local Bus Specification Revision 2.2 and supports transfer operations between primary and secondary 32-bit PCI interfaces. A PCI-to-PCI bridge is an interface IC that connects two peripheral component interconnect buses and allows devices on one bus to communicate with resources on the other. In the interface hierarchy, the PI7C8150BNDE belongs to the PCI interface controller and bus-bridge category, where it provides protocol translation, transaction handling, and bus arbitration between conventional PCI domains. It is intended for established PCI systems rather than modern PCI Express designs. The PI7C8150B family provides 32-bit primary and secondary ports that run as fast as 66 MHz. Both bus interfaces support asynchronous operation, which allows the bridge to operate between systems whose bus timing is not synchronized. The PI7C8150B-33 member is distinguished by a maximum 33 MHz operating frequency, while the PI7C8150B family described by the manufacturer supports operation up to 66 MHz. As a PCI Local Bus Specification Revision 2.2 device, the bridge targets legacy parallel PCI infrastructure, including systems that require a secondary PCI bus behind a host bridge. Its 256-pin PBGA construction provides the dense pin access needed for two 32-bit PCI interfaces, associated control signals, clock inputs, power rails, and ground connections. The package is identified by distributors as a 17 mm by 17 mm 256-ball PBGA. Typical uses include industrial PCI adapter designs, embedded legacy PCI systems, industrial control equipment, data-acquisition systems, and PCI expansion chassis that require a bridge between primary and secondary buses. The asynchronous operating capability is particularly relevant when the connected PCI domains do not share identical clock timing. Designers must also account for the physical size, routing density, and power requirements of a 256-pin BGA package. The primary design consideration is that PI7C8150BNDE must be evaluated as a conventional PCI bridge rather than a PCI Express device. Board design requires exact BGA layout, controlled-impedance routing, adequate power-plane integrity, and compliance with the PCI Local Bus Specification Revision 2.2. Firmware and system configuration must also support the bridge and its bus-routing requirements. This page consolidates the verified manufacturer and distributor information for the PI7C8150BNDE, distinguishes the 66 MHz part from the 33 MHz PI7C8150B-33 option, and identifies same-family replacement candidates. Detailed electrical values, pricing, pin assignments, and lifecycle details remain explicitly marked where the supplied source data does not provide verified values.
PI7C8150BNDI - Async 2-Port PCI Bridge | Diodes Incorporated
Diodes Incorporated PI7C8150BNDI is an asynchronous 2-port, 32-bit PCI-to-PCI bridge interface IC packaged in a 256-pin plastic BGA measuring 17 mm by 17 mm. It is designed for asynchronous PCI Local Bus operation and compliance with PCI Local Bus Specification Revision 2.2. The bridge provides the central interface between two PCI bus segments, allowing compatible PCI devices and host systems to communicate across separate bus domains. A PCI bridge is an interface IC that connects one PCI Local Bus segment to another while coordinating bus ownership, transactions, arbitration, and protocol translation. Within the product hierarchy, the PI7C8150BNDI is a PCI interface controller, a bridge device, and an interface IC used in legacy PCI computer and industrial expansion systems. Its asynchronous architecture supports independently timed bus segments, which can help isolate traffic and extend usable system topology compared with placing additional loads directly on one shared PCI bus. Key verified features include asynchronous operation, two PCI ports, a 32-bit PCI data path, and support for PCI Local Bus Specification Revision 2.2. The device is identified by distributor listings as the PI7C8150BNDI 256-PBGA variant and as a 2-port, 32-bit PCI bridge. These characteristics distinguish it from ordinary endpoint devices because the bridge participates directly in PCI bus arbitration and forwards transactions between two host or peripheral bus segments. Technically, the bridge is intended to bridge PCI Local Bus domains rather than operate as a memory controller, serial transceiver, or conventional parallel processor interface. The asynchronous design is significant in systems where the two PCI segments do not share identical timing or loading conditions. Exact clock frequencies, voltage limits, transaction throughput, arbitration timing, reset requirements, and electrical characteristics were not included in the supplied verified data and therefore are not asserted here. Typical uses include industrial computers, embedded PCI expansion systems, test equipment, communications appliances, and legacy PCI-compatible platforms that require an additional bridged bus segment. In these applications, the bridge can separate devices onto a second PCI bus and reduce direct electrical loading on the primary segment. System designers must still validate electrical timing, firmware initialization, interrupt routing, and platform support before deployment. A primary design consideration is software and firmware compatibility. Because the device bridges an established PCI Local Bus architecture, operating-system support, BIOS or device-tree configuration, interrupt topology, and vendor reference designs must be confirmed for the target platform. Hardware review should also include the manufacturer's PI7C8150B documentation and the exact pin and layout requirements associated with the BNDI package suffix. This product page combines verified manufacturer and distributor facts, current sourcing information, structured technical context, and explicit data-gap markers. It is intended to help engineers evaluate the PI7C8150BNDI for legacy PCI bridging applications while clearly separating published facts from parameters that still require manufacturer-document review.
PI7C8152AMAE - 2-Port 66MHz PCI-to-PCI Bridge | Diodes Incorporated
The Diodes Incorporated PI7C8152AMAE is a 2-port PCI-to-PCI bridge interface IC that provides fully compliant 32-bit, 66 MHz operation per the PCI Local Bus Specification Revision 2.2, operates from a single 3.3 V supply, and is packaged in a 160-pin MQFP (28x28 mm). It bridges one Primary Bus to two Secondary Buses, allowing legacy PCI add-in cards and peripherals to be expanded behind a single host bridge slot. A PCI bridge is a bus-controller IC that sits between two segments of the PCI Local Bus and manages arbitration, transaction forwarding, and the electrical buffering of shared signals. Within the taxonomy, PI7C8152AMAE is a PCI-to-PCI bridge, which is a type of PCI interface controller, which belongs to the broader class of bus interface ICs and therefore to the semiconductor and interface IC categories. Historically the Intel 21152 was the reference device for this function, and the PI7C8152 family was designed as its enhanced competitor. Key differentiating features of the PI7C8152A include support for synchronous bus transactions between devices on the Primary and Secondary Buses operating up to 66 MHz, two independent Secondary Bus ports, 32-bit PCI data width, and operation from a single 3.3 V supply. The MAE suffix denotes the industrial/commercial temperature option supplied in the 160-pin MQFP industrial package. Unlike the PI7C8152B, the PI7C8152A supports synchronous transactions only. Architecturally, the device combines separate primary and secondary bus controllers with a transaction scheduler, a 32-bit arbiter, and buffered address/data control lines. Buffering isolates the two bus segments electrically and lets the bridge absorb the loading of one extra bus level, which matters when several 32-bit expansion cards must share limited host-bridge fanout. Typical uses include industrial and instrumentation PC expansion slots, medical imaging and diagnostic systems, legacy server and test-equipment chassis, RAID and storage controllers on secondary buses, and industrial field-bus gateways that still expose legacy PCI mezzanine connectors. When designing around this device, verify that the target system still uses a 3.3 V PCI bus rather than the older 5 V signalling convention, and confirm the MQFP-160 land pattern and thermal pad requirements on the motherboard. Because the PCI Local Bus is a legacy architecture, supply continuity and long-term availability are the dominant procurement risks, so sourcing from a stocked distributor is usually advisable. This page consolidates distributor availability, verified device specifications, pin-compatible bridge alternatives, and practical design and sourcing notes that are not consolidated anywhere in the original manufacturer datasheet.
PI7C8152BMAE - 2-Port 66MHz PCI Bridge | Diodes
The Diodes Incorporated PI7C8152BMAE is a 2-port PCI-to-PCI bridge interface IC supporting 32-bit synchronous and asynchronous transfers at up to 66 MHz. It is compliant with the 32-bit, 66 MHz implementation of PCI Local Bus Specification Revision 2.2 and PCI-to-PCI Bridge Specification Revision 1.1, and it is supplied in a commercial-grade 160-pin MQFP package measuring 28 mm by 28 mm. A PCI-to-PCI bridge is a specialized interface IC that connects a host-side PCI bus to one or more downstream PCI buses. It belongs to the hierarchy of PCI interface controllers, bus interface integrated circuits, interface devices, and semiconductors. By separating primary and secondary bus traffic through a bridging controller, the PI7C8152BMAE allows PCI-compatible equipment to extend a 32-bit PCI topology while maintaining compatibility with the Revision 2.2 bus specification. The verified device characteristics include two PCI ports, 32-bit bus width, operation from 33 MHz to 66 MHz, PCI 2.2 compliance, PCI-to-PCI Bridge 1.1 compliance, and a 160-MQFP package. A related distributor listing also identifies 3.3 V operation and a 10 pF feature. These details distinguish it as a conventional, parallel-bus PCI interface solution rather than a serial PCIe controller. The PI7C8152BMAE is applicable to legacy PCI expansion systems, industrial controller interfaces, embedded PCI equipment, data-acquisition platforms, and test systems that retain 32-bit PCI buses. In these systems, the bridge can isolate a secondary bus segment and support devices operating with the same 32-bit width and up to 66 MHz clock rate. System designers must also account for the bridge-specific interrupt, arbitration, and reference-clock requirements described by the manufacturer documentation. PCB implementation is the primary design consideration. The 160-pin MQFP footprint requires a fine-pitch, high-pin-count land pattern, careful escape routing, and verified multilayer-board construction. Power, ground, clock, and high-speed parallel bus signals should follow the manufacturer’s recommended topology, with particular attention to return paths and trace-length relationships. This page combines verified manufacturer and distributor information with package, compatibility, sourcing, and design guidance intended to help engineers evaluate the PI7C8152BMAE efficiently. Because the verified data does not expose a complete public pin table, the page does not reproduce guessed pin assignments; the manufacturer datasheet and product page remain the authoritative references for implementation.
PI7C8952AFAE - Dual UART PCI Bridge | Diodes Incorporated
Diodes Incorporated PI7C8952AFAE is a dual-channel PCI-to-UART interface bridge with two UART channels, 128-byte FIFO capability, 3 V or 5 V supply support, and a 100-LQFP package measuring 14 mm by 14 mm. It is designed to add two asynchronous serial interfaces to a PCI-based embedded system while presenting a standardized bus interface to the host. A PCI-to-UART bridge is an interface IC within the broader hierarchy of PCI interface controllers, peripheral interface controllers, interface ICs, and semiconductors. It provides the electrical and protocol translation required between a parallel PCI host bus and asynchronous serial channels. Such bridges are useful when a legacy PCI platform needs to communicate with sensors, modems, industrial controllers, or other equipment that uses UART signaling. The verified product information identifies a two-channel UART configuration and a 128-byte FIFO for each function. FIFO buffering helps a host service received serial data without requiring the CPU to retrieve every byte immediately. The device can operate from either 3 V or 5 V supplies, which provides flexibility when integrating it with systems using different primary rail voltages. A 100-LQFP package offers a substantial pin count for power, ground, host-bus, and dual-channel UART connectivity. The PI7C8952AFAE integrates PCI host-bus connectivity with two independent UART channels. Its architecture is intended to reduce the need for discrete host-interface logic while consolidating serial ports in one device. However, the supplied source data does not specify the supported PCI signaling mode, UART baud-rate range, parity and data-bit formats, interrupt behavior, electrical timing, or operating-temperature limits. Those parameters should be confirmed against the manufacturer datasheet before schematic capture or firmware development. Typical uses include industrial PCI instrumentation, data-acquisition systems, test equipment, embedded control platforms, and legacy computer expansion systems. In each case, the bridge can connect a PCI host to two serial peripherals while the FIFO separates buffered receive data from direct host-bus transactions. The exact host-software configuration remains application-specific because an operating-system driver or platform-specific initialization routine may be required. The principal design consideration is package and signal-integrity planning for the 100-pin LQFP. The board layout must preserve the device's power and ground connectivity, route PCI signals according to the manufacturer's recommendations, and keep UART signals away from noisy switching nodes. Decoupling, termination, and clock requirements should be implemented only after the complete pin assignments and electrical tables have been obtained from the official datasheet. This page consolidates the verified product identity, package information, channel count, FIFO depth, supply options, sourcing links, and engineering-use guidance for the PI7C8952AFAE. It also separates documented facts from parameters that remain unavailable in the supplied data, helping engineers plan a search for the datasheet, evaluate procurement, and determine whether the dual-UART PCI bridge matches a legacy platform.
PI7C8954AFHE - PCI Quad UART Bridge | Diodes Incorporated
Diodes Incorporated PI7C8954AFHE is a PCI-to-UART interface bridge with four UART channels, supplied in a 144-pin LQFP package measuring 20 mm by 20 mm. The device is categorized for 3 V and 5 V UART-controller applications and is identified by the verified product data as an IC PCI Quad UART Bridge. Its package provides 144 external leads for the PCI interface, four serial-port interfaces, power, grounding, and associated control signals. A PCI-to-UART bridge is an interface controller that allows a host system operating across a PCI bus to exchange serial data with up to four UART peripherals. In the product hierarchy, the PI7C8954AFHE is an interface IC, a PCI bridge, and a multi-channel UART interface controller. This bridge function places it between a PCI-capable embedded or industrial system and external serial devices, reducing the need for four separate host-interface adapters. The verified listing identifies the PI7C8954AFHE as a four-channel UART bridge in a 144-LQFP package. It is associated with 3 V and 5 V UART-controller applications, while a separate distributor listing classifies the product as a PCI bridge and PCI-to-UART interface. These attributes make it relevant to embedded systems, industrial controllers, data-acquisition equipment, multiport communication systems, and legacy PCI systems that require several serial ports. The 144-LQFP construction distinguishes the PI7C8954AFHE from single-channel UART transceivers such as MAX232DR or USB-to-UART devices such as CP2102N-A01-GQFN20R. Its defining advantage is integration: one PCI-to-quad-UART device consolidates four UART channels behind a single PCI host interface. The available source data does not expose detailed clocking, electrical, timing, or channel-level specifications, so those values should be confirmed against the manufacturer datasheet before design release. A typical integration places the bridge on a PCI host board, connects each UART channel to the required serial transceiver or logic-level interface, and routes power and ground carefully across the 144 leads. System designers must account for the available voltage domains, peripheral interface requirements, signal integrity, and thermal performance associated with the large LQFP package. The principal design consideration is verification: the supplied search results confirm the bridge function, four UART channels, 144-LQFP package, 20 mm by 20 mm body size, inventory, and one unit price, but they do not provide a complete manufacturer pin table or electrical limit table. Confirm pin assignments, operating voltages, PCI signaling details, UART baud-rate behavior, and power requirements against the authoritative datasheet before PCB routing or firmware development. This page consolidates verified distributor inventory, pricing, package information, interface classification, cross-reference findings, and practical implementation guidance. It clearly separates confirmed PI7C8954AFHE attributes from unverified details and avoids presenting unsupported substitutes as guaranteed drop-in replacements.

Diodes Incorporated PI7C8958AFHE is an active PCI-to-UART interface bridge with eight UART channels, a 3.3 V and 5 V supply capability, and a 144-pin LQFP package measuring 20 mm by 20 mm. It is designed to bridge a PCI host bus to eight serial communications channels, placing legacy UART connectivity behind a PCI interface. The verified product data identifies the device as an octal PCI UART bridge and lists an operating temperature range of -40 °C to 85 °C. A PCI bridge is an interface controller that translates transactions between parallel expansion-bus protocols and peripheral-facing interfaces. The PI7C8958AFHE sits in the interface IC hierarchy as a PCI interface bridge, with the UART interface providing a practical expansion path for systems that need multiple serial ports. Its eight-channel arrangement can reduce the number of separate UART controller components required in multi-port equipment. The principal verified characteristics are PCI protocol support, a PCI-to-UART bridge function, eight UART channels, 3.3 V and 5 V supply operation, 10 mA supply current, and a 144-LQFP surface-mount package. The 144-pin package exposes substantially more interface and control signals than a conventional small-outline UART transceiver, making careful PCB layout and pin-level verification essential. Its 20 mm by 20 mm footprint is materially larger than common SOIC or MSOP interface packages. Technically, the PI7C8958AFHE is intended for embedded systems, industrial equipment, multiport servers, test systems, and other PCI-based products that require several UART channels. The octal architecture consolidates eight serial interfaces behind one PCI bridge, but designers must confirm PCI host compatibility, connector requirements, signal termination, operating-system support, and the complete datasheet pin assignment before production release. A key design consideration is that the listed 10 mA supply current should not be treated as a complete system power budget because regulator efficiency, I/O loading, and other board loads are not included. The 3.3 V and 5 V supply entries should also be validated against the device's detailed electrical tables before selecting rail voltage, decoupling, and interface-level components. Typical uses include industrial controller cards, communications appliances, embedded test equipment, and legacy-port expansion systems. Because no complete pin table, electrical limits, clocking details, UART configuration, PCI transaction behavior, or pricing schedule was present in the verified results, each missing item is identified explicitly rather than inferred. This page combines verified product identity, package information, sourcing links, and engineering-selection guidance without inventing unsupported electrical details.
PI7C9X110BNB - 32-Bit 66MHz PCI Bridge | Diodes Inc
Diodes Incorporated PI7C9X110BNB is a PCIe-to-PCI non-transparent reversible bridge interface IC supporting a 32-bit PCI bus at 66 MHz in a 160-pin LFBGA package measuring 12 mm by 12 mm. It is designed to translate PCI Express traffic to conventional PCI transactions while providing reversible bridging between the two bus architectures. A PCI-to-PCI bridge is an interface semiconductor used to connect otherwise incompatible expansion buses. Within the hierarchy of interface ICs, bus bridges convert protocol, signaling, and transaction formats so that legacy PCI equipment can operate through a PCIe host system. This makes the PI7C9X110BNB relevant to industrial computers, embedded systems, test equipment, and legacy peripheral adapters that require PCI compatibility. The verified source information identifies the device as a 32-bit, 66 MHz PCI bridge with a reversible, non-transparent PCIe-to-PCI architecture. Its 160-LFBGA package provides a compact surface-mount implementation for multilayer PCB layouts. The 12 mm by 12 mm body and high pin count make controlled escape routing, uninterrupted power distribution, and careful thermal design essential during implementation. Because this is a high-speed bus bridge, signal integrity strongly influences system performance. Differential PCIe routing and clock distribution require a continuous reference plane, controlled impedance, minimized stub lengths, and appropriately placed termination and decoupling networks. The supplied source material confirms the bridge's bus width, operating frequency, architecture, and package, but it does not provide verified voltage values, pin assignments, power ratings, or complete timing tables. Typical use cases include PCI industrial controllers, embedded motherboard designs, data-acquisition systems, communications equipment, and legacy PCI expansion systems. The reversible bridge function can simplify system architecture when equipment must accommodate both PCIe hosts and PCI devices without maintaining separate processor interfaces. Its 66 MHz maximum PCI operating frequency supports legacy 32-bit PCI hardware in systems where higher-speed conversion is not required. Designers should begin with the manufacturer datasheet and device pinout rather than inferring BGA connectivity from the distributor listings. The BGA footprint requires appropriate escape routing, via structures, solder-mask and paste patterns, and thermal verification. Power and ground distribution must be designed around the device's verified supply requirements once those values are obtained from the datasheet. This page consolidates verified distributor and manufacturer information, distinguishes the PI7C9X110BNB from unverified functional equivalents, and adds package-aware replacement, comparison, and design guidance. It also identifies missing electrical and pin-level data explicitly so procurement and engineering decisions can proceed without fabricated specifications.
PI7C9X111SLBFDE - PCIe to PCI Reversible Bridge | Diodes Incorporated
The Diodes Incorporated PI7C9X111SLBFDE is a single-lane (x1) PCI Express to 32-bit/66 MHz PCI reversible bridge from the SlimLine family, packaged in a 128-pin LQFP (14x14 mm). It delivers forward and reverse bridging between a PCIe root complex and legacy PCI devices, making it a drop-in solution for industrial, embedded, and communications platforms that still require PCI peripherals. The part supports PCIe 1.1 (2.5 GT/s) and integrates clock power management, hot-plug, and active-state power management (ASPM). A PCI Express bridge is a protocol translation device that maps PCIe Transaction Layer packets onto the conventional PCI bus protocol (or vice versa), allowing legacy PCI silicon to be used on modern PCIe-only SoCs and chipsets. Within the broader taxonomy, this part sits in the hierarchy: PCIe bridge -> bridge IC -> interface IC -> integrated circuit -> semiconductor. Reverse bridging is a key differentiator, allowing a PCIe endpoint port to expose a PCI bus to legacy masters - a configuration not supported by cheaper one-way bridges. Key specifications include 32-bit/66 MHz PCI bus support, x1 PCIe link, 5.0 GT/s raw signaling rate on the PCI side, low-power operation via clock gating, and integrated reference clock. The 128-LQFP package exposes all PCI and PCIe signaling, including REQ_L/GNT_L, AD[31:0], C/BE_L[3:0], PERST#, REFCLK+, REFCLK-, and the standard JTAG/sideband pins. Strapping pins (TM1, REQ_L[3:2], REVRSB) configure polarity, clock power management, and PCI bus mode at PERST# de-assertion. Architecturally, the PI7C9X111SL uses a non-transparent or transparent transaction layer with on-chip buffering and arbitration. Forward and reverse modes share the same die; the only configuration difference is the REVRSB strapping pin and bridge-side register programming. Compared to a discrete PCIe PHY plus controller FPGA, the integrated solution saves board area and reduces BOM cost while meeting PCI-SIG compliance. Typical applications include legacy PCI card carriers on modern PCIe motherboards, industrial control backplanes, telecom baseband cards that still need PCI peripherals, medical imaging systems, and avionics/transportation platforms with long PCI lifecycles. It is commonly paired with PCIe-root SoCs such as NXP i.MX, Intel Atom-class processors, or Xilinx/Altera FPGAs that lack a native PCI host bus. When designing with the PI7C9X111SLBFDE, pay attention to the REFCLK routing (100 MHz differential, PCIe-compliant), the PERST# sequencing relative to the host and the device tree enumeration order, and the bulk-decoupling requirements on each VCC pin. Reverse mode also requires that the BIOS/firmware recognize the bridge as a PCI-to-PCIe bridge so legacy PCI resources are mapped correctly. This page synthesizes distributor pricing (as of 2026-10-09), drop-in same-package alternatives, and practical design notes not found on the Diodes marketing page - giving engineers one place to evaluate the bridge against PCI-SIG and application requirements.
PI7C9X111SLBFDE - PCIe-to-PCI Reversible Bridge | Diodes Inc
The Diodes Incorporated PI7C9X111SLBFDE is a single-lane PCI Express (x1 PCIe) to PCI / PCI-X reversible bridge, packaged in a 128-pin LQFP (14x14 mm) with a 3.3V single supply. The device implements forward and reverse bridging between a x1 PCIe root complex / endpoint and a 32-bit, 33/66 MHz conventional PCI or 66 MHz PCI-X bus, enabling designers to extend the life of legacy PCI peripherals in modern PCIe-only platforms. A bridge IC (also called a PCI-to-PCI or PCIe-to-PCI bridge) is a protocol-translation device that connects two physically and electrically distinct bus segments. The PI7C9X111SL sits in the connectivity hierarchy as: bridge -> bus converter -> interface IC -> signal-conditioning semiconductor. It appears in systems that must glue a downstream legacy I/O controller (NIC, SCSI, industrial I/O, video capture) to an upstream host that no longer exposes a PCI bus, which is common after the industry migrated to PCIe-only chipsets around 2010-2015. Key electrical and functional features include a single 3.3V supply rail, integrated PHY for PCIe Gen1 (2.5 GT/s) and PCI/PCI-X bus interface logic, support for both forward (PCIe primary, PCI secondary) and reverse (PCI primary, PCIe secondary) bridge modes, configurable via strapping pins, and 32-bit datapath operation up to 66 MHz. The 128-LQFP package exposes a generous pin budget so designers can route full 32-bit PCI plus x1 PCIe plus sideband control signals without an internal serializer. The architecture is based on Diodes' (formerly Pericom) SlimLine PCIe-to-PCI bridge family, with on-chip transaction translation, posted write buffering, completion tracking, and standard PCI configuration space. Power consumption is optimized for embedded and add-in-card applications where a small footprint and low thermal dissipation are required. The part is qualified to operate over commercial temperature ranges suitable for embedded computing, networking, and industrial platforms. Typical applications include PCIe-mini-PCI adapter cards, industrial PCs with legacy PCI I/O, embedded systems migrating from PCI to PCIe hosts, networking line cards that still require PCI peripheral controllers, test and instrumentation backplanes, and POS / kiosk / medical platforms with long-life PCI peripherals. The reversible bridge mode also supports evaluation boards and protocol-analyzer use cases where the host side of a PCI design needs to be exposed as a PCIe endpoint. When designing with this device, pay close attention to the 3.3V rail decoupling (100 nF + 10 µF near the supply pins), PCIe AC-coupling capacitor placement on the transmit pair, and the strapping-pin configuration table for forward vs reverse mode selection. Reference clock routing and REFCLK+ / REFCLK- length matching must follow the PCIe CEM specification. Always verify the secondary PCI bus timing budget against the loaded PCI segment to avoid protocol violations at 66 MHz operation. This page synthesizes distributor pricing, same-package drop-in alternatives, application companion chips, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for board bring-up, sourcing, and second-source planning.
PI7C9X111SLBFDE - x1 PCIe-to-PCI Reversible Bridge | Diodes Inc
The Diodes Incorporated PI7C9X111SLBFDE is a SlimLine x1 PCI Express to 32-bit/66 MHz PCI reversible bridge housed in a 128-pin LQFP (14x14 mm) package. According to the Diodes product page, the part delivers high-performance forward and reverse bridging with very low power consumption and a small footprint, making it the latest addition to the PCI Express Bridge SlimLine family of solutions. Key headline specifications include: 32-bit/66 MHz PCI interface, x1 PCIe upstream port, reversible bridge architecture, and 128-LQFP (14x14) footprint. A PCI Express-to-PCI bridge is a specialized interface IC that converts transactions between the modern PCIe serial point-to-point protocol and the legacy parallel PCI bus, enabling legacy PCI cards (NICs, video capture, industrial I/O) to operate behind newer PCIe-only host chipsets. It sits within the broader taxonomy of interface ICs -> bus bridges -> protocol converters -> semiconductors, and is one of the few commercially active reversible bridge families in production. Compared with conventional PCIe-to-PCI bridges, the PI7C9X111SL adds bidirectional traffic support, allowing the legacy PCI device to expose memory or DMA windows to the PCIe host. Key features highlighted on the PI7C9X111SL datasheet include compliance with PCI Express Base Specification 1.1, 32-bit/66 MHz conventional PCI bus support, REQ/L[3:2]/REVRSB pin-strap configuration, and an optional Clock Power Management mode entered via TM1 strap. The bridge supports PME#, INTx, and conventional PCI interrupt/clock request signaling for legacy adapter passthrough. Its small-footprint 128-LQFP makes it attractive for embedded single-board computers and industrial backplanes with tight board real estate. The device uses a packetized split-transaction architecture to translate PCIe TLP packets into conventional PCI cycles, with internal buffering sized for the x1 link. The reversible bridge capability means the chip can also operate as a PCI-to-PCIe bridge (PCI primary side facing the host), which is uncommon and useful in adapter cards that need to expose a single PCIe endpoint while presenting legacy PCI bus timing upstream. Typical uses are industrial drive-in backplanes, retrofit board adapters that need to expose a single PCIe endpoint while presenting legacy PCI bus timing upstream, and embedded SBCs continuing to host legacy add-in cards. The 128-LQFP package supports a common load of 60 trailing-combe CTPs, enabling cost-effective board assembly. When designing with this part, ensure the upstream PCIe link is wired with proper AC coupling capacitors and 100-ohm differential impedance. The TM1 strap selection for Clock Power Management should be tied high or low through a 10k resistor at board level. The bridge requires a 100 MHz reference clock for the PCIe side and a PCI clock for the downstream bus - both must be present before PERST# de-assertion. This page synthesizes distributor pricing, drop-in alternatives from Diodes Incorporated and competitors, and practical design notes not consolidated in the manufacturer datasheet. Compliance status and parametric proximity have been cross-checked against DigiKey, Mouser, Octopart, and the Diodes product page.
PI7C9X111SLBFDEX - PCIe to PCI Reversible Bridge | Diodes Inc
The Diodes Incorporated PI7C9X111SLBFDEX is a SlimLine x1 PCI Express to 32-bit/66 MHz PCI reversible bridge IC in a 128-pin LQFP (14x14 mm) package. It delivers high-performance, low-power transparent bridging between a PCIe x1 upstream port and a conventional 32-bit/66 MHz PCI bus, supporting both forward (PCIe-to-PCI) and reverse (PCI-to-PCIe) bridge operation. The part is supplied on Tape & Reel and is rated for industrial temperature operation. A PCIe-to-PCI bridge is a protocol-translating device that lets modern systems lacking a native PCI host controller still address legacy PCI cards, or conversely lets a legacy PCI host expose an endpoint to a PCIe root complex. Bridges like the PI7C9X111SLBFDEX sit in the interconnect hierarchy between the system root complex and the I/O subsystem, allowing product designers to extend the lifecycle of mature 32-bit/66 MHz PCI peripherals (data-acquisition cards, frame grabbers, industrial I/O) on newer PCIe-only CPUs, or to add PCIe endpoint capability to legacy PCI platforms. Key features include 32-bit/66 MHz PCI bus support, a single-lane (x1) PCIe interface, reversible bridge direction, very low power consumption, a small LQFP-128 footprint, and clock power management. The reversible architecture is enabled by pin strapping on the TM1 ball: when TM1 is strapped low, the part uses REQ_L[3:2] and REVRSB to invoke the Clock Power Management feature at PERST# de-assertion. The PI7C9X111SLBFDEX is part of Diodes' SlimLine PCIe bridge family, optimized for compact embedded designs. Typical applications include legacy PCI card migration onto PCIe-only host boards, industrial single-board computers, test and measurement backplanes, embedded vision and frame-grabber adapters, and reverse-bridge use cases where a legacy PCI host must communicate with a PCIe endpoint. The -EX suffix on the part number denotes the Tape & Reel packaging option. When designing with this device, pay close attention to PCIe reference-clock routing and AC-coupling capacitor placement, ensure PERST# timing complies with the PCIe CEM specification, and follow the datasheet's hot-plug and clock-power-management pin-strap recommendations. The part operates from a single 3.3 V supply. This page synthesizes distributor pricing, drop-in alternative analysis, and practical design notes for the PI7C9X111SLBFDEX that are not consolidated in the manufacturer datasheet, helping engineers evaluate sourcing and second-source options.
PI7C9X2G404SLBFDE - 4-Port PCIe 2.0 Switch | Diodes
Diodes Incorporated PI7C9X2G404SLBFDE is a 4-port, 4-lane PCI Express 2.0 packet switch in a 128-pin LQFP exposed-pad package. It supports two channels and is designed as a low-power, lead-free system component for embedded PCIe routing applications. The verified distributor data identifies it as a 4-port, 4-lane PCIe 2.0 packet switch; additional electrical characteristics were not supplied in the retrieved source set and are marked as required data below. A PCI Express packet switch is a semiconductor device that manages traffic between PCIe endpoints and a host or upstream port. It belongs to the packet-switch, interface-IC, and semiconductor hierarchies, using serialized high-speed lanes to distribute PCIe traffic among downstream devices. A four-port, four-lane configuration is useful when a system must consolidate storage, networking, graphics, or add-in-card connections behind a PCIe interface. The available data confirms four downstream ports, four lanes, PCIe 2.0 classification, two channels, a 128-pin LQFP package, and an exposed thermal pad. The package is identified as 14 x 14 mm by distributor data. The manufacturer description identifies embedded systems, Wi-Fi routers or gateways, printers, storage, combo cards, HBAs, and set-top systems as possible use cases. The switch is intended to provide a compact PCIe connectivity solution while keeping system power and board area under control. Its exact lane data rate, auxiliary voltage, operating temperature, reference-clock requirements, lane impedance, and electrical timing are not stated in the verified data, so those parameters remain explicitly unresolved rather than being inferred. PI7C9X2G404SLBFDE is suitable for board designs that require a PCIe switching function and a 128-pin LQFP land pattern. Design work should preserve the exposed-pad thermal and electrical requirements, validate the complete PCIe signal-integrity stack-up, and confirm pin-level functions against the manufacturer datasheet before layout release. This page consolidates verified distributor specifications, manufacturer product positioning, commercial availability information, and carefully qualified replacement findings. Because the provided evidence does not establish enough distinct pin-compatible devices, the alternatives section avoids padding the list with unsupported equivalents. For pricing, LCSC showed a starting price of $9.8100 and in-stock status in the retrieved results, while Mouser, DigiKey, Arrow, and other distributors provided listing or datasheet references. Pricing and availability should be reconfirmed at the time of purchase.
PI7C9X2G404SLQ - PCIe 2.0 4-Port Packet Switch AEC-Q100 | Diodes
The Diodes Incorporated PI7C9X2G404SLQ is an automotive-compliant PCI Express 2.0 packet switch providing 4 ports over 4 lanes in a 128-pin LQFP (14x14 mm) package, qualified to AEC-Q100 and manufactured to meet lead (Pb)-free and green system requirements. A PCI Express packet switch is a switching fabric device that expands a single upstream PCIe root-port link into multiple downstream ports, allowing one host controller to communicate with several endpoints simultaneously. Within the system hierarchy, it sits between the PCIe controller (root complex) and endpoint devices, forming part of the interconnect layer of a computing or embedded platform alongside bridges and retimers. Key features of the PI7C9X2G404SLQ include its SlimLine low-power architecture, four-port/four-lane PCIe Gen2 topology, AEC-Q100 automotive qualification, and Pb-free green manufacturing. These attributes make it well suited to designs where lane count is limited but multiple PCIe endpoints must be supported, and where extended temperature and reliability requirements apply. Technically, the device belongs to the Pericom PI7C9X2G404SL packet-switch family (Diodes acquired Pericom Semiconductor). The SL (standard) and SLQ (automotive/qualified) variants share the same silicon architecture and SlimLine package; the SLQ variant is specifically characterized and qualified for automotive deployment. Compliance with the PCI Express Base Specification enables interoperability with standard root complexes and endpoints without custom drivers. Typical applications include automotive infotainment and telematics platforms, Wi-Fi routers and gateways, embedded industrial systems, storage controllers, HBAs, combo cards, and printers, where a cost-effective PCIe fan-out is required. A key design consideration: confirm lane allocation across the four downstream ports, since the device provides four lanes total; heavily loading one port with all four lanes starves the remaining ports. Verify power budget and reference-clock distribution per the manufacturer datasheet. This page synthesizes verified manufacturer data, drop-in alternatives, application guidance, and practical design notes not found in a single datasheet or distributor listing.
PI7C9X3G1224GPAHFCE - PCIe Gen3 12-Port 24-Lane Switch | Diodes
The Diodes Incorporated PI7C9X3G1224GPAHFCE is a PCI Express (PCIe) Gen3 packet switch supporting 24 lanes of 8 Gb/s Gen3 SERDES in flexible port configurations from 3 ports up to 12 ports, housed in a 324-ball H-FCBGA (19 x 19 mm) package shipped in tray form (84 pieces per tray). A PCIe packet switch is a switching fabric device that connects a root complex or upstream host port to multiple downstream endpoints, arbitrating and routing PCIe transaction-layer packets between ports. Within the system hierarchy, it sits at the fabric level of the PCIe architecture - above individual endpoint controllers and below the root complex - and is a key building block of server, storage, and expansion platforms that need more PCIe connectivity than a host CPU natively provides. Key features of the PI7C9X3G1224GP family include the flexible tile-based port architecture, where a basic cell called a tile consists of 8 ports and 16 lanes for Tile 0, allowing variable lane-width allocation per port; support for the PCIe Gen3 data rate of 8 GT/s per lane; and 24 total lanes that can be aggregated into wide ports (x4, x8) or split into narrow ports (x1, x2) depending on system topology requirements. Technically, the switch implements the full PCIe packet routing engine: it decodes TLP headers, performs address-based routing in the switch's internal hierarchy of virtual PCI-to-PCI bridges, and manages link training, equalization, and lane reversal on each SERDES interface. The architecture allows the flexible port configuration by allocating variable lane width for each port, so designers can tailor fan-out without changing silicon. Typical applications include server expansion backplanes, NVMe SSD storage controllers with multiple drive bays, PCIe expansion chassis, industrial host adapter cards, and communications platforms aggregating multiple endpoint cards onto a single host root port. When designing with this device, verify the port-to-lane mapping of the chosen package option against your board topology, and plan the power delivery and SERDES layout (controlled-impedance differential pairs, AC coupling, reference clock distribution) early, since 24 Gen3 lanes place significant demands on stackup and trace budget. This page synthesizes distributor availability data, drop-in alternatives within the PI7C9X3G1224GP family, and practical design notes not found in a single manufacturer datasheet.
PI7C9X3G816GP - 8-Port 16-Lane PCIe 3.0 Switch | Diodes
The Diodes Incorporated PI7C9X3G816GP is a PCI Express Gen 3 packet switch that supports 16 lanes of Gen3 SERDES in flexible 2-port, 3-port, 4-port, 5-port and 8-port configurations, housed in a 324-ball HFCBGA (19x19 mm) package. A PCIe packet switch is an interface fabric device that sits in the PCI Express hierarchy between a root complex and multiple endpoints. It expands a single upstream PCI Express link into several downstream links, forwarding TLPs (Transaction Layer Packets) between ports based on address routing. Within the system hierarchy, a packet switch belongs to the PCI Express interconnect family: root complex to switch to endpoints, enabling fan-out expansion for storage controllers, network interface cards, and host adapters without saturating the host root port. Key features of the PI7C9X3G816GP include PCI Express Gen3 (8 GT/s) SERDES with 16 lanes total, flexible lane-width allocation per port, and support for 2-port through 8-port partitioning. This flexibility allows a single PCB design to address multiple SKU tiers: a 2-port x8 design for storage, or an 8-port x2 fan-out for dense backplanes. The switch implements standard PCI Express packet-switch functions including non-posted and posted transaction forwarding. Technically, the device integrates high-speed Gen3 SERDES blocks with receiver equalization and transmitter de-emphasis required for reliable 8 GT/s operation over backplane-length channels, while the switch fabric performs cut-through packet routing with address-based and ID-based forwarding per the PCI Express Base Specification. Typical applications include NVMe SSD storage systems, server expansion backplanes, industrial host adapter cards, and networking line cards where a host PCIe Gen3 root port must serve multiple endpoints. Design consideration: allocate one configuration strap set and verify lane-width partitioning early, since flexibly partitioned ports share the fixed 16-lane SERDES pool and the chosen partition determines ball usage. This page synthesizes datasheet facts, drop-in family alternatives, application guidance, and design notes not consolidated in the manufacturer datasheet.
PI7C9X752FAE - Dual UART with 64-Byte FIFO | Diodes Inc.
Diodes Incorporated PI7C9X752FAE is a high-performance dual UART interface controller with a 1.62 V to 3.6 V supply-voltage range, a 64-byte FIFO, IrDA 1.1 support, and a 48-pin TQFP package measuring 7 mm by 7 mm. The device combines two independent UART channels with buffered serial-data handling in a surface-mount package suitable for compact embedded communication systems. A UART, or universal asynchronous receiver-transmitter, is a serial interface that converts parallel digital data into framed asynchronous serial signals and reverses that process on reception. Within the interface-controller hierarchy, a UART controller can include FIFO buffering, modem-control signaling, interrupt handling, and IrDA-compatible support. The PI7C9X752FAE is therefore positioned as a multi-channel communications IC rather than a general-purpose logic device or standalone transceiver. The verified defining features are its dual-channel architecture, 1.62 V to 3.6 V operating range, 64-byte FIFO, and IrDA 1.1 capability. A FIFO helps decouple the host processor from temporary variations in serial traffic by buffering received or transmitted characters. The 1.62 V minimum operating voltage also makes the controller suitable for low-voltage embedded systems, provided that the attached processor, transceiver, and external circuitry use compatible logic levels. The PI7C9X752FAE is listed as an RS485 controller, IrDA 1.1, and UART interface device. These functions make it relevant to systems that need multiple asynchronous serial channels, whether for external data acquisition, industrial equipment, infrared data links, or communications between a host controller and peripheral ICs. Because the verified data does not expose the complete register map, clock configuration, electrical timing limits, or pin assignments, those details must be checked in the manufacturer datasheet before final circuit design. Typical implementation places the controller beside one or more external interface devices. One UART channel may connect to an RS-485 transceiver for a longer-distance industrial bus, while the other supports point-to-point serial equipment or an IrDA-compatible peripheral. The controller does not itself replace the physical-layer transceiver for RS-485 or infrared signaling, so appropriate external hardware remains necessary for those links. Designers should confirm logic thresholds, peripheral clocking, interrupt requirements, and the manufacturer-recommended input and output capacitance before layout. Decoupling connections should be short, and the 7 mm by 7 mm TQFP footprint requires careful assembly planning because its 48 leads provide less routing space than a larger package. Signal-routing and grounding practices should also separate the controller's digital interfaces from external transceiver return paths. This page consolidates the verified distributor descriptions, package information, interface functions, and availability evidence for PI7C9X752FAE. It also distinguishes confirmed capabilities from unavailable specifications, helping engineers evaluate the dual-UART controller before requesting the authoritative datasheet and committing the 48-TQFP footprint to a PCB design.
PI7C9X754FCE - 4 UART with 64-Byte FIFO | Diodes Incorporated
Diodes Incorporated PI7C9X754FCE is a quad UART interface IC with four independently controlled UART channels, each containing a 64-byte transmit and receive FIFO. It operates from 1.62 V to 3.6 V, includes 5 V tolerant serial inputs, and supports Intel or Motorola data-bus interface selection. The device is packaged in a 64-LQFP 10 x 10 mm package for compact embedded serial-interface designs. A UART, or universal asynchronous receiver-transmitter, is a communication controller that converts parallel data from a host processor into serial data and converts received serial data back into a parallel format. The PI7C9X754FCE belongs to the UART interface IC, interface controller, and clock-and-timing interface hierarchy, providing four channels in one package and reducing board area compared with four discrete UART devices. Key features include a 16C550-compatible register set, independent control of each UART, transmit and receive FIFO level counters, and programmable transmit and receive FIFO trigger levels for interrupt or DMA-driven operation. The 64-byte FIFO buffers help absorb bursts of serial traffic while the host processor is busy, reducing the probability of receiver overrun and improving software flow-control flexibility. The PI7C9X754FCE can be configured for RS485 Controller and IrDA 1.1 use according to distributor product information. The Intel/Motorola bus selection allows compatibility with different processor interfaces, while the programmable FIFO trigger levels support interrupt-driven or DMA-based data movement. These features make the device suitable for multi-channel embedded systems where four UART resources must share limited host I/O. Typical applications include industrial serial hubs, POS terminals, test equipment, printers, modems, multiport communications modules, and embedded control systems. The low 1.62 V to 3.6 V operating range is appropriate for modern 3.3 V digital systems, while 5 V tolerant serial inputs simplify interfaces to legacy equipment. Care is still required when connecting external signals because tolerance applies to the specified serial inputs, not necessarily every control pin. For robust PCB implementation, place the device close to the protected connector or transceiver pins, route serial traces away from clocks and switching-power nodes, and validate input levels, termination, grounding, and system-level RS485 or IrDA requirements. This page combines verified manufacturer and distributor information, pricing references, replacement analysis, and practical design guidance beyond a raw datasheet parameter list.
