PI6C557-03LEX

PI6C557-03LEX - 200MHz PCIe Clock Generator | Diodes

The Diodes Incorporated PI6C557-03LEX is a 200 MHz PCI Express and Ethernet clock generator with two differential HCSL outputs, supplied in a 16-TSSOP package. It accepts a 25 MHz crystal input and uses Pericom PLL techniques to generate selectable 25 MHz, 100 MHz, 125 MHz, and 200 MHz clock frequencies. The verified distributor data identifies a 3.3 V supply, a -40°C to +85°C operating range, and two clock outputs. Its clock-generation and spread-spectrum functions position it within the clock and timing IC category as a phase-locked-loop-based timing device for high-speed digital systems. A clock generator produces reference and data-rate clocks for digital circuits that require stable timing, phase control, and predictable edge placement. In a PCI Express system, a spread-spectrum clock can reduce electromagnetic-interference peaks by distributing clock energy over a frequency band. The PI6C557-03 family is designed for PCI Express and Ethernet clock requirements, making it suitable for computer, embedded, communications, and industrial equipment where a local reference clock is needed. The PI6C557-03LEX provides selectable frequency operation and two differential HCSL output pairs according to the manufacturer datasheet. Its HCSL outputs are intended for high-speed signaling, while configurable spread-spectrum operation helps control radiated and conducted EMI. The manufacturer states that the differential outputs use open-source drivers and require external series and shunt resistors; resistor values and placement should therefore follow the applicable PCI Express layout guidance. The device accepts a 25 MHz crystal input and generates two pairs of differential outputs at 25 MHz, 100 MHz, 125 MHz, or 200 MHz, depending on configuration. This frequency range supports both low-frequency clock distribution and higher-speed PCI Express clocking. The 3.3 V operating supply and 16-TSSOP surface-mount package support compact PCB designs where external clock conditioning and controlled spread-spectrum operation are required. Typical applications include PCI Express endpoint and motherboard clocking, embedded computer platforms, Ethernet interface equipment, communications infrastructure, and industrial control systems. The device is most appropriate when a system needs configurable clock selection, differential outputs, and spread-spectrum EMI reduction rather than a simple low-frequency oscillator or single-ended clock buffer. PCB implementation should preserve short, controlled-length clock traces, provide the required external termination network, and place crystal and decoupling components close to the device. Differential pair routing, return paths, resistor placement, and output configuration must be checked against the manufacturer datasheet and the target PCI Express or Ethernet design guidelines. This page combines verified manufacturer and distributor information with application guidance and replacement analysis.

The Diodes Incorporated PI6CG33A06ZLFEX is an ultra-low-jitter, 6-output PCIe 5.0/6.0/7.0 clock generator with integrated on-chip output termination, housed in a 40-pin VQFN (5 mm x 5 mm) package. It accepts a reference input and generates 25 MHz and 100 MHz differential outputs while maintaining sub-30 fs RMS phase jitter that outperforms the 80 fs CK440Q PCIe specification. A clock generator is an integrated circuit that synthesizes one or more precise timing signals from a reference oscillator, providing the heartbeat that synchronizes CPUs, memory, and high-speed serial links. In the broader IC hierarchy it sits below clock buffers and above generic PLLs, and it belongs to the timing-IC family within power management and signal-chain semiconductors. Key features include six differential outputs with individual OE (output enable) pins for granular power management, integrated 85 ohm on-chip termination that eliminates 24 external resistors, 300 ns SMBus 2.0-compatible data hold time, and support for PCIe Gen 1/2/3/4/5/6/7 standards. The on-chip termination simplifies board layout and shrinks BOM count by 24 resistors versus discrete implementations. The device uses Diodes' proprietary PLL architecture with fractional-N feedback to achieve the jitter performance required for PCIe 7.0 while maintaining backward compatibility with PCIe 5.0 and 6.0. Each output pair is independently controllable through SMBus registers, which is essential for modern servers that need to power down unused PCIe lanes to meet energy-efficiency targets. Typical applications include AI server motherboards, NVMe SSD controllers, networking switches, high-performance computing accelerator cards, and CXL-attached memory modules. The compact VQFN-40 5x5 mm footprint also makes the part attractive for space-constrained add-in cards and OCP accelerator designs. When designing with this device, follow the recommended power-rail decoupling layout: 1 uF and 0.1 uF ceramic capacitors placed within 2 mm of each supply pin. Maintain 100 ohm differential impedance on each output pair and route length-match within 5 mils to preserve jitter performance.

PI6CG33A06ZLFEX-13R

PI6CG33A06ZLFEX-13R - 6-Output PCIe 5.0/6.0/7.0 Clock Generator | Diodes Inc

The Diodes Incorporated PI6CG33A06ZLFEX-13R is a 6-output ultra-low jitter clock generator designed to meet the demands of the PCI Express 7.0 specification while maintaining backwards compatibility with PCIe 5.0 and 6.0. It delivers 100 MHz HCSL outputs (and 25 MHz reference) from a single reference input, housed in a 40-pin VQFN (5x5 mm) package with integrated on-chip termination that eliminates up to 24 external resistors. Each output features an individual OE (output enable) pin for granular power management, and the device supports SMBus 2.0 programming with 300 ns data hold time for legacy compatibility, plus 0 ns hold time for newer SMBus revisions at 100 kHz and 400 kHz. A clock generator IC is a semiconductor device that takes a low-jitter reference clock (typically from a crystal oscillator or external source) and produces one or more synchronized output clocks, often at multiplied or divided frequencies and with specific output formats (HCSL, LVCMOS, LVDS, LVPECL). PI6CG33A06ZLFEX-13R belongs to the timing generator family, which sits in the broader hierarchy of clock and timing ICs -> clock generators -> PCIe timing components -> power management and system timing for computing and storage platforms. PCIe clock generators are essential building blocks in servers, workstations, NVMe storage, networking switches, and graphics cards where deterministic jitter performance is required by the PCI-SIG specification. Key features include ultra-low additive jitter to meet PCIe 7.0 jitter budgets, integrated 100-ohm differential on-chip termination matching PCIe HCSL impedance directly, six individually-controlled HCSL outputs operating at 100 MHz, and a 25 MHz reference output for downstream devices. The 3.3 V supply simplifies integration with common server and storage platform rails. SMBus programming allows frequency, format, output enable, and spread-spectrum parameters to be configured in-system. From an architectural perspective, the PI6CG33A06 uses a PLL (phase-locked loop) synthesizer to multiply a 25 MHz crystal reference into six phase-aligned 100 MHz HCSL outputs. The on-chip termination eliminates the need for external 100-ohm resistor networks typically required on each HCSL pair, significantly reducing BOM count and PCB complexity while preserving the precise impedance matching required by PCIe 5.0/6.0/7.0 physical-layer compliance testing. Typical applications include PCI Express Gen5/Gen6/Gen7 server riser cards, NVMe storage controller clocking, workstation motherboards, 5G base-station backplane clock distribution, and AI accelerator PCIe retimer cards. The 100 MHz HCSL output format is required by PCIe CEM specification for all downstream add-in cards and baseboard connections. When designing with this device, place 0.1 uF decoupling capacitors as close as possible to each VDD pin and follow the layout recommendations in the manufacturer datasheet. Maintain 100-ohm differential trace impedance on each HCSL pair and minimize stubs to preserve jitter margin. Use the SMBus lines carefully with proper pull-up resistors and keep them away from switching noise sources. This page synthesizes distributor availability and pricing, drop-in PCIe alternatives from Diodes and other vendors, and practical layout notes not found in the bare datasheet, giving engineers a single decision point for PCIe 7.0 clock tree selection.

PI7C1401AZFEX I2C/SPI Quad Port Expander | Diodes Incorporated
PI7C1401AZFEX

PI7C1401AZFEX I2C/SPI Quad Port Expander | Diodes Incorporated

Diodes Incorporated PI7C1401AZFEX is an I2C-bus/SPI to quad port expander designed for managing common port types such as SFP+ and QSFP+ modules. It provides an I2C-bus or SPI host interface, an interrupt output to the host, and four I2C interfaces for downstream port management. General-purpose pins support low-speed control signaling to connected modules, making the device suitable for networking, telecommunications, and other multi-port systems. The PI7C1401AZFEX operates from a 1.8 V to 3.3 V supply and is packaged in a 56-pin TQFN measuring 11 mm by 5 mm. Its dual-serial-host architecture allows a system controller to reach several peripheral or module ports through one low-speed management link. Rather than assigning a separate controller interface to every port, the PI7C1401 centralizes port-management traffic and reports module or port events through a dedicated host interrupt. Four downstream I2C interfaces are the principal expansion function of the device. These interfaces suit modules that expose management registers, status indicators, or configuration controls through I2C. The upstream SPI or I2C connection supports integration with network processors, field-programmable gate arrays, embedded controllers, and other digital systems. General-purpose control pins add flexibility for slower module-management signals and reduce the need for additional discrete interface components. The PI7C1401 is specifically intended for common networking-port form factors, including SFP+ and QSFP+ equipment. It can be used in optical transceiver cages, switch and router line cards, telecommunications equipment, and industrial control systems that need scalable port management. Its four-port structure is especially useful where a host must monitor or configure multiple pluggable modules while retaining a compact board footprint. Designers should use the manufacturer pin-description table and recommended application schematic when assigning signals. The 1.8 V to 3.3 V supply requirement must be reconciled with the voltage levels used by the host and downstream modules. Decoupling, exposed-pad connection, ground-plane continuity, and signal-routing guidance should follow the manufacturer layout recommendations. Interrupt behavior and the electrical characteristics of the I2C and SPI interfaces should also be checked against the system timing budget. This page organizes the PI7C1401AZFEX function, supply range, package, port-expansion architecture, application fit, and procurement information. It also identifies the technical fields that require confirmation from the manufacturer datasheet, helping engineers evaluate the device without confusing general port-expander functionality with package-specific or timing-specific guarantees.

PI7C21P100NHE 64-Bit PCI Interface IC | Diodes Incorporated

Diodes Incorporated PI7C21P100NHE is a 64-bit PCI interface IC used as a PCI-to-PCI bridge, with an operating supply range of 2.3 V to 2.7 V and 3 V to 3.6 V. The device is identified with a 304-CSBGA (31x31) supplier package designation and a 304-BGA package case in the manufacturer-oriented product listing. The PI7C21P100NHE is intended for systems requiring PCI interface bridging and embedded PCI connectivity. A PCI interface IC is a specialized semiconductor that connects PCI buses or peripheral buses and helps translate or coordinate data transactions within a computer system. Within the broader hierarchy, the PI7C21P100NHE belongs to interface ICs, interface controllers, PCI bus controllers, and embedded system semiconductors. Its function is determined by the bridge architecture, signal handling, supported operating conditions, and package implementation. The documented headline characteristics are the 64-bit PCI interface, dual listed supply ranges of 2.3 V to 2.7 V and 3 V to 3.6 V, and the 304-CSBGA (31x31) package designation. These parameters make the part relevant to embedded platforms where a compact, high-pin-count interface solution is required. The exact pin assignments, clocking architecture, performance limits, current consumption, and configuration requirements must be confirmed from the manufacturer datasheet before a board design is released. Typical uses for this device include embedded industrial controllers, PCI-compatible data-acquisition equipment, legacy PCI expansion systems, and customized embedded platforms that require a dedicated PCI bridge. The tight integration of a complex bridge into a BGA package favors multilayer PCB construction and careful high-speed signal-layout practices. Thermal and power planning should account for the device’s actual operating profile under the manufacturer’s stated maximum conditions. The most important design step is to verify the complete pinout and electrical requirements against the manufacturer documentation for the exact ordering code. Package descriptions differ across listings, so the board footprint should be selected from the authoritative mechanical drawing rather than inferred from a marketplace summary. Confirm supply tolerances, decoupling requirements, clock sources, reset behavior, and PCI signal-integrity constraints during schematic review. This page consolidates the product identification, sourcing URLs, technical constraints, and design considerations needed to evaluate the PI7C21P100NHE. It also distinguishes verified attributes from parameters that must be obtained from the official datasheet, helping engineers make a controlled design decision without relying on an unreviewed family-level substitution.

PI7C7300ANAE - 3-Port PCI Bridge Interface IC | Diodes Incorporated
PI7C7300ANAE

PI7C7300ANAE - 3-Port PCI Bridge Interface IC | Diodes Incorporated

Diodes Incorporated PI7C7300ANAE is a 3-port PCI-to-PCI bridge interface IC packaged in a 272-ball PBGA measuring 27 x 27 mm. The device is intended to bridge PCI-compatible expansion or embedded-system buses, consolidating the physical and logical interface functions needed when one PCI host must communicate with multiple PCI agents. Its defining published features are the three-port bridge configuration, conventional parallel PCI interface, and high-density 272-ball BGA package. A PCI-to-PCI bridge is a specialized interface integrated circuit within the broader PCI interface-controller hierarchy. It sits electrically between two PCI bus segments and allows compatible PCI devices or subsystems on the secondary side to communicate with the host-side PCI bus. Such bridges are especially relevant to embedded computing, industrial control, communications equipment, and legacy PCI expansion systems where a bus translation function is required but a newer host-to-PCI interface is not appropriate. The PI7C7300ANAE provides three PCI ports for designing systems around multiple downstream PCI agents. This makes it useful where a central host must coordinate several bus participants, including endpoint devices, bridges, or controller functions implemented in an embedded subsystem. Because the device uses a large-array BGA package, its implementation depends on multilayer PCB routing, controlled impedance, solid thermal management, and careful high-speed signal routing rather than a simple two-row peripheral package. The 272-ball PBGA is the principal mechanical constraint when evaluating this component. Its 27 x 27 mm footprint provides dense access to the PCI bridge's power, ground, clock, control, and data contacts, but it also demands exact land-pattern compliance, ball-to-pad alignment, and assembly-process validation. Tube packaging is listed in the verified distributor data, so procurement and assembly planning should account for the component's handling requirements before committing to a production build. Typical applications include embedded PCI backplanes, industrial controller platforms, communications gateways, test systems, and specialized expansion chassis that retain conventional PCI connectivity. In these systems, the PI7C7300ANAE serves as the central bus-routing element rather than as a general-purpose processor, memory device, or isolated interface transceiver. Adjacent Ethernet, USB, serial, and industrial interface components may support the wider system, but the bridge remains the component responsible for PCI-to-PCI transaction forwarding. Designers should obtain the manufacturer datasheet and verify all electrical, timing, clocking, power, thermal, and pin-level requirements before schematic capture or PCB layout. The high-density BGA also benefits from assembly-capability review, impedance-controlled stack-up selection, via placement around the device, and adequate power-plane distribution. This page consolidates verified distributor and datasheet-link information, purchasing considerations, application context, and the limits of the currently available substitute data.

PI7C7300DNAE - 3-Port PCI-to-PCI Bridge | Diodes
PI7C7300DNAE

PI7C7300DNAE - 3-Port PCI-to-PCI Bridge | Diodes

Diodes Incorporated PI7C7300DNAE is a three-port PCI-to-PCI bridge interface IC designed for bridging conventional PCI bus traffic in embedded and industrial systems. It operates from a 3.3 V to 3.6 V supply, is specified at 660 mA, and is housed in a 272-ball PBGA package measuring 27 mm by 27 mm. The PI7C7300DNAE is a surface-mount interface device intended for designs requiring centralized PCI host-bus expansion and translation between PCI transactions and a downstream PCI segment. A PCI-to-PCI bridge is an interface IC that extends a PCI host bus through a transparent bridge while preserving transaction handling across the bus boundary. Within the broader semiconductor hierarchy, it is a specialized bus-interface controller and therefore part of the interface IC category. Its three-port architecture allows multiple PCI resources to be organized behind a shared upstream interface, reducing the need for separate host bridges when system expansion, monitoring, or industrial add-in cards must share a PCI connection. The PI7C7300DNAE operates with a 3.3 V to 3.6 V core supply and is rated for 660 mA. Its three-port configuration is the principal functional feature for systems that must consolidate more than one downstream PCI connection. The 272-PBGA, 27 mm by 27 mm package provides a high pin count for the address, data, control, arbitration, clock, and power interfaces associated with a multiport bridge. Surface-mount construction supports automated assembly but requires careful escape routing and multilayer PCB planning. Technically, the device belongs to the conventional PCI interface generation rather than a compactPCI, PCIe, or USB bridge. Conventional PCI systems separate address and data signaling and use dedicated control, arbitration, interrupt, and clock resources. The three-port topology therefore requires validation at the system level to confirm arbitration behavior, interrupt routing, bus ownership, and the electrical loading introduced by every connected card or module. Typical implementation areas include industrial PCI expansion systems, embedded test equipment, data-acquisition controllers, legacy communication adapters, and PCI carrier systems that need multiple downstream resources. A three-port bridge is especially useful when three downstream bus segments require coordinated operation, but the complete system must remain within the electrical, protocol, and timing limits defined by the manufacturer datasheet. A critical design consideration is the 272-ball BGA layout. The PCB should use the manufacturer land pattern, controlled escape routing, and uninterrupted reference planes for the many high-speed bus signals. Power and ground distribution should be evaluated for the specified 660 mA operating point, with attention given to simultaneous switching activity, connector loading, thermal performance, and the clock and signal-integrity requirements of the target PCI topology. This page organizes the PI7C7300DNAE electrical limits, package information, sourcing questions, functional alternatives, and design considerations into one engineering reference. It also distinguishes true pin-compatible replacements from broader PCI-bridge alternatives, helping designers assess whether a candidate can occupy the same 272-ball footprint or merely provides a similar bus-bridging function.

PI7C8140AMAE

PI7C8140AMAE - PCIe-to-PCI Bridge | Diodes Incorporated

Diodes Incorporated PI7C8140AMAE is a dedicated PCIe-to-PCI bridge interface IC with one PCI Express port and one 32-bit/66 MHz PCI port, supplied in a 128-FQFP package measuring 14 x 20 mm. The device supports reversible bridging, allowing the PCIe-to-PCI or PCI-to-PCIe direction to be configured according to system requirements. It is intended for systems that need to connect a legacy parallel PCI subsystem to a serial PCI Express host interface. A PCI-to-PCI bridge is an interface IC that translates transactions between unlike bus architectures. PCI Express uses serial, point-to-point links, while conventional PCI is a parallel, shared bus. The PI7C8140AMAE acts as the protocol and electrical boundary between these two domains, helping system designers retain PCI-compatible expansion equipment while upgrading the primary interconnect to PCIe. The verified product information describes the bridge as a two-port device with a 32-bit/66 MHz PCI interface. The main verified differentiation is reversible operation. Instead of implementing only one fixed bridge direction, the PI7C8140AMAE can be configured for forward or reverse bridging. This flexibility is useful in test equipment, embedded platforms, industrial controllers, and legacy PCI cards that must interoperate with a PCIe host system. The physical implementation uses 128 leads in an FQFP package, providing the pin resources required by the bridge and its associated I/O and power connections. The supplied distributor listings identify the part as a PCI-to-PCI Bridge Interface IC and explicitly describe it as a two-port bridge containing one PCI Express port and one 32-bit/66 MHz PCI port. They also identify a 128-FQFP, 14 x 20 mm package. Detailed operating limits, electrical characteristics, clocking requirements, power rails, signal names, and full pin assignments were not included in the verified dataset and therefore are not inferred here. Those values must be confirmed from the manufacturer datasheet before layout or qualification. In a typical system, the bridge would sit between a PCIe root complex and a legacy PCI bus segment. The downstream PCI devices exchange parallel bus transactions with the bridge, while the bridge serializes those transactions for transmission over PCIe. Reversible configuration can also place the bridge in the opposite direction when the host and target roles require it. Correct clocking, reference-voltage, termination, decoupling, and trace routing remain essential in high-speed implementation. This product page combines the verified distributor and manufacturer-linked data with package, sourcing, comparison, and design guidance that is not available as a single consolidated source. It also distinguishes confirmed facts from values that require the complete datasheet, helping engineers identify what can be used for initial component selection and what still needs verification before PCB release.

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.

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.

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.

The Diodes Incorporated PI7C8150AND-33 is a two-port PCI-to-PCI bridge interface IC operating at 33 MHz and packaged in a 256-pin PBGA measuring 17 x 17 mm. The device bridges conventional PCI bus domains, supporting system designs that require a host bus and an additional PCI bus segment to communicate through a dedicated interface controller. A PCI-to-PCI bridge is an interface integrated circuit used to extend and isolate conventional Peripheral Component Interconnect bus segments. It belongs to the PCI interface controller class, the interface IC hierarchy, and the broader semiconductor category. Its primary function is to translate and coordinate bus transactions so that devices on separate PCI segments can communicate while each segment operates as an independent bus. The PI7C8150AND-33 provides two PCI ports, a 33 MHz operating frequency, and a 256-pin PBGA package. Its 17 x 17 mm ball-grid-array construction supports dense board layouts where fine interconnect pitch and many power, ground, and signal connections are required. Current ratings, voltage limits, electrical timing, host interfaces, and supported PCI signaling modes should be confirmed in the manufacturer datasheet before schematic or layout release. This bridge architecture is useful in embedded industrial controllers, legacy PCI expansion systems, test equipment, communication appliances, and embedded computing platforms that still depend on conventional PCI topology. The two-port organization allows a motherboard or mezzanine design to divide devices across multiple bus segments instead of placing every device on one shared PCI bus. The principal engineering trade-off is board complexity. A 256-pin PBGA requires careful escape routing, multilayer construction, ball assignment review, and assembly-process control. Power delivery and return paths must also support the bridge's switching and I/O requirements while minimizing crosstalk on high-fanout bus signals. Use the manufacturer pin-description table to assign every power, ground, clock, reset, interrupt, and PCI data contact. Confirm the complete board stack-up, ball-map orientation, decoupling strategy, and manufacturing rules before release because the public product summary does not provide a complete production pin list. This page organizes the verified device identity, package information, sourcing path, family relationship, and practical integration considerations into a concise engineering reference. It also highlights the distinction between the ordered -33 configuration and related PI7C8150 family members without substituting unverified performance claims.

PI7C8150ANDE

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
PI7C8150BMAE

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.

PI7C8150BMAIE - 66MHz PCI Bridge | Diodes Incorporated

Diodes Incorporated PI7C8150BMAIE is an asynchronous PCI-to-PCI bridge interface IC with two 32-bit PCI ports, operation up to 66 MHz, a 3 V to 3.6 V supply range, and a 208-FQFP (28x28 mm) package. It is designed for systems that need one PCI bus segment to communicate with another through a transparent asynchronous bridge rather than a conventional host controller. A PCI-to-PCI bridge is an interface IC within the broader PCI interface controller hierarchy. It translates and arbitrates transactions between two PCI Local Bus segments, allowing compatible peripheral cards and bus masters on the secondary segment to access resources through the primary segment. The PI7C8150B family supports asynchronous operation, meaning its primary and secondary buses do not have to operate from one shared clock. The bridge's primary and secondary interfaces are both 32 bits wide, and the standard PI7C8150B supports operation up to 66 MHz. The PI7C8150B-33 family member provides a lower-frequency version rated to 33 MHz. A 3 V to 3.6 V core supply range supports integration into conventional 3.3 V PCI systems while avoiding the need for a 5 V-only interface arrangement. In a PCI system, the bridge can separate bus traffic between processor-side and expansion-card segments. Its asynchronous architecture is useful when the two sides run at different clock rates or when independent bus timing is preferred. The 208-pin FQFP exposes the numerous address, data, control, arbitration, and power pins required by two full 32-bit PCI interfaces. Typical uses include industrial PCI systems, embedded instrumentation, industrial control equipment, data-acquisition systems, and legacy PCI expansion platforms. In each case, the bridge must satisfy the PCI Local Bus electrical and transaction-routing requirements while preserving the intended peripheral ordering and arbitration behavior. PCB design should provide the required 3.3 V supply decoupling and route the many high-speed address and data signals with short, continuous paths. The manufacturer's pin-description table should be used directly when assigning all 208 package connections and when checking board constraints for this large fine-pitch bridge. This page combines manufacturer functionality, package and interface characteristics, drop-in replacement analysis, application guidance, and design cautions to support faster component selection and PCB implementation.

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.

PI7C8150DMAE PCI-to-PCI Bridge | Diodes Incorporated

The Diodes Incorporated PI7C8150DMAE is a 2-port PCI-to-PCI bridge interface IC designed to connect two PCI bus segments in embedded and industrial computing systems. The device is associated with a 208-FQFP package measuring 28 mm by 28 mm, providing a high pin count for PCI data, control, power-management, and auxiliary signal routing. It is identified as an asynchronous PCI interface device, making it suitable for systems that need protocol bridging between separate PCI buses rather than simple point-to-point serial communication. A PCI-to-PCI bridge is a specialized interface semiconductor that translates and buffers transactions between two Peripheral Component Interconnect bus segments. It sits within the interface-IC and semiconductor hierarchy and can isolate traffic, improve bus fan-out, and support legacy PCI system architectures. The PI7C8150DMAE is particularly relevant to embedded industrial equipment, industrial control systems, legacy PCI expansion platforms, test equipment, and data-acquisition systems where a conventional PCI interface must be extended to another PCI segment. The Diodes Incorporated product listing identifies the PI7C8150DMAE as a PCI-to-PCI bridge interface with two ports. Its 208-FQFP package supports the numerous signals required by a conventional PCI bridge, while its size and pin count make careful high-speed layout essential. The available product information also identifies Tube packaging, lead-free construction, and RoHS status for this part. Tube packaging is intended for automated pick-and-place and board assembly, but the exact tube quantity and shipping configuration should be confirmed before production planning. The primary design consideration is signal integrity. Because the device bridges a parallel peripheral bus, routing must minimize trace-length mismatch, maintain continuous reference planes, provide proper termination, and avoid splits across PCB layers. Power and ground distribution also require careful treatment because multiple PCI signal groups and auxiliary functions can create simultaneous switching activity. A complete 208-pin symbol, pin names, and electrical limits cannot be reconstructed from the available product listings; use the manufacturer datasheet and its pin-description tables for layout and schematic work. PI7C8150DMAE is most appropriate when maintaining an existing PCI topology matters more than adopting a modern serial interconnect. Its selection should be based on the host bus, target bus, clocking requirements, interrupt routing, and the exact electrical characteristics defined in the manufacturer documentation. This page combines package information, application guidance, replacement constraints, and practical layout considerations to support early design decisions without inventing unverified electrical values.

Diodes Incorporated PI7C8150DNDE is a two-port asynchronous PCI-to-PCI bridge IC operating from a 3 V to 3.6 V supply and packaged in a 256-BGA surface-mount package measuring 17 mm by 17 mm. The device is supplied in tube packaging and is identified as a lead-free, RoHS-compliant interface circuit. A PCI-to-PCI bridge is an interface IC that connects two PCI domains or links within a computer system. It belongs to the broader PCI interface family, specialized interface controllers, and semiconductor hierarchy. Rather than providing a general-purpose processor function, this component translates and coordinates PCI traffic between compatible bus interfaces while preserving the electrical signaling required by the PCI architecture. The PI7C8150DNDE provides two PCI ports in a single package, reducing the number of discrete bridge devices needed when a system requires more than one interconnection path. Its 3 V to 3.6 V operating supply range supports conventional 3.3 V system rails. The 256-BGA package also offers a high pin count for routing the numerous address, data, control, clock, and power connections associated with two PCI interfaces. As an asynchronous bridge, the device is intended for systems in which the linked PCI interfaces do not share a common clock domain. This makes it useful in embedded computers, industrial controllers, communication appliances, and legacy PCI expansion systems where two PCI resources must be connected through a dedicated bridge. The exact bridge mode, protocol timing, and supported host configurations should be confirmed against the manufacturer datasheet before implementation. The 256-BGA package is a surface-mount solution intended for multilayer PCB assembly. Its 17 mm by 17 mm footprint allows access to the package's high pin count, but it also requires careful escape routing, power-plane distribution, and thermal design. Tube packaging is appropriate for production processes that use a compatible component-placement and tray-handling sequence. Designers should pay particular attention to signal integrity when routing the PCI bus through a fine-pitch BGA. Use continuous reference-plane return paths, minimize stub branches, apply device-decoupling recommendations, and observe the manufacturer layout requirements for the package. Because this is a complex interface IC rather than a power component, SOA is not applicable, and thermal qualification depends on the complete board environment. This product summary combines the verified package, supply-voltage, port-count, packaging, and environmental attributes with practical guidance for PCI bridge implementation, BGA layout, and system integration. It also identifies the absence of confirmed drop-in substitutes so engineers can validate interchangeability against electrical and pin-level requirements before redesigning a production PCB.

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.

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.

PI7C8152BMAIE - 2-Port 66MHz PCI-to-PCI Bridge | Diodes Inc

The Diodes Incorporated PI7C8152BMAIE is a 2-port PCI-to-PCI bridge interface IC operating at 66 MHz with a 32-bit PCI bus width, packaged in a 160-lead MQFP (28 x 28 mm) surface-mount package. It is the bridge solution of choice for extending a legacy PCI segment behind a host bridge, allowing two independent 32-bit PCI buses to operate on either side of the bridge. A PCI-to-PCI bridge is a specialized interface IC that sits between two PCI bus segments and converts one bus's protocol, arbitration and electrical signaling into the other. In the system hierarchy it belongs to the PCI interface controller family, which sits between the CPU/memory subsystem and expansion peripherals. Bridges are used to add PCI slots beyond the limits of a single host bridge, to isolate electrical loading, and to allow two buses running at different speeds or loads to coexist. Key features of the PI7C8152BMAIE include full 32-bit, 66 MHz PCI operation, two independent bridge ports, and backward compatibility with 33 MHz PCI agents. Operating at the full 66 MHz ceiling of the conventional PCI specification gives designers headroom for demanding video capture, storage controller, DSP and industrial data-acquisition cards without bandwidth arbitration penalties. The 160-pin quad flat package provides the pin count needed for the full 32-bit data path plus the auxiliary sideband signalling required by the PCI specification. Internally, the device implements separate bus transceivers and arbitration logic for each of its two ports, so traffic crossing the bridge is buffered rather than simply passed through. That buffering decouples bus loading on the far side of the bridge from the near side, improving signal integrity and allowing each segment to support its own device population and clock domain discipline. Because it regenerates rather than re-times signals, the bridge isolates capacitive loading and reduces the stub effects that plague long shared PCI segments. Typical applications include PCI-PCI bridges in industrial chassis, embedded PCI carrier boards, multi-segment server peripherals, video frame grabbers, RAID host adapters, and legacy industrial expansion systems where a single PCI segment cannot populate all required slots. It is also used in test and measurement platforms that need to isolate high-bandwidth DUT buses from the host system. A key design consideration is that the PI7C8152BMAIE requires careful 32-bit PCI routing with matched-length, impedance-controlled traces and proper termination, plus correct peripheral ordering and isolation. Because the device is a legacy peripheral for the conventional PCI bus, confirm host-bridge and operating-system support for bridging before committing to a new design.

PI7C8154ANAE - 2-Port 64-bit PCI Bridge | Diodes Incorporated

The Diodes Incorporated PI7C8154ANAE is a two-port PCI-to-PCI bridge interface integrated circuit operating at 64-bit and 66 MHz in a 304-BBGA package measuring 31 mm by 31 mm. It is designed for systems that need to connect separate PCI bus segments while maintaining asynchronous operation across the bridged interfaces. A PCI bridge is a specialized interface semiconductor that extends a PCI bus through a controlled communication boundary. Within the PCI interface hierarchy, a PCI-to-PCI bridge connects two PCI domains or bus segments, allowing compatible PCI devices and subsystems to communicate without treating both segments as one uninterrupted electrical bus. The PI7C8154ANAE occupies the interface-IC category and is particularly relevant to legacy and industrial PCI system expansion. The PI7C8154ANAE's principal documented characteristics are its two-port bridge configuration, 64-bit data width, 66 MHz operating frequency, asynchronous bridge operation, and 304-BBGA package. These characteristics place it in the role of a high-bandwidth protocol translator between PCI buses. The package's 304-ball construction supports the numerous power, ground, signal, and interface connections expected in a complex multi-bus bridge. Typical implementation contexts include industrial computers, embedded PCI expansion systems, legacy server or workstation designs, and test equipment that retains a PCI interface. The 64-bit path supports efficient transfer of wide data payloads, while the 66 MHz operating point represents the upper operating frequency identified for this device in its product documentation. The most important design task is PCB-level integration. A 304-BBGA device requires a land pattern, escape routing, reference-plane management, power distribution, and thermal design that account for every specified ball assignment. Use the manufacturer datasheet pin-description table and recommended land pattern when defining the board footprint and routing all power, ground, clock, and PCI signals. This page organizes the verified device identity, package information, interface characteristics, application considerations, and comparison candidates into an engineering-oriented selection guide. It also separates known differences among related PI7C8154 ordering codes, helping designers verify compatibility before committing a complex board layout.
