PI7C9X754FFEX - Quad UART Interface IC | Diodes Incorporated

The Diodes Incorporated PI7C9X754FFEX is a quad UART interface IC with four UART channels and a 64-byte FIFO in an 80-LQFP (12 x 12 mm) package. The device is identified in distributor listings as an RS485 controller with IrDA 1.1 support, providing a consolidated interface solution for systems that require multiple serial communication channels. A UART interface IC is a semiconductor device that converts parallel digital data into serial signals and receives serial data in parallel form. It belongs to the interface IC hierarchy, which also includes RS485 controllers, IrDA transceivers, and other communication adapters. The PI7C9X754FFEX combines four UART functions in one package, reducing the number of separate serial-interface devices required in embedded equipment. The main documented features include a quad-UART configuration, a 64-byte FIFO per channel according to the product listing, RS485 controller functionality, and IrDA 1.1 support. These features make the device relevant to industrial control, instrumentation, embedded communications, and multi-channel data-acquisition systems where several serial ports must operate within one design. The 80-LQFP (12 x 12 mm) package provides a defined lead arrangement for compact but high-pin-count PCB designs. Because the device integrates four UART channels, board-level design requires careful review of each channel's data, control, interrupt, and supply connections. The manufacturer datasheet should be used to assign the complete pinout, power requirements, timing values, and electrical limits before PCB routing. Typical uses include industrial controllers with multiple serial-device connections, test equipment communicating with several instruments, data-acquisition gateways, and embedded systems that bridge host processors to RS485 or IrDA peripherals. In each case, the integrated FIFO can help buffer serial traffic, while the quad-channel architecture reduces component count compared with four separate UART interface devices. Designers should confirm signal levels, transceiver requirements, interrupt allocation, and package land pattern in the manufacturer datasheet. RS485 applications may require external line drivers or transceivers because the PI7C9X754FFEX is identified as an RS485 controller rather than a complete isolated RS485 transceiver. This page summarizes the available product information and provides engineering guidance for evaluating the device in a new design. This product page consolidates the confirmed PI7C9X754FFEX features, package information, sourcing links, application guidance, and the key qualification checks engineers need when comparing multi-channel UART interface ICs.

PI7C9X754ME - Quad UART with 64-Byte FIFO | Diodes

Diodes Incorporated PI7C9X754ME is a high-performance quad UART interface IC with four independently controlled channels, 64-byte transmit and receive FIFOs, and operation from 1.62 V to 3.6 V in a 100-MQFP (14 mm × 20 mm) package. The device supports RS485 controller operation, IrDA 1.1, 16C550-compatible registers, and Intel or Motorola data-bus interfaces. A universal asynchronous receiver/transmitter, or UART, is an interface controller that converts parallel data from a processor into serial transmissions and converts incoming serial data back into a parallel format. In the broader semiconductor hierarchy, this device belongs to interface ICs, where it sits between a host processor and serial communication links. Its four channels allow one controller to manage multiple independent data streams while sharing a common host interface. Each UART includes a 64-byte transmit FIFO, a 64-byte receive FIFO, transmit and receive FIFO level counters, and programmable trigger levels. These functions support efficient DMA and interrupt-driven data transfer. The serial inputs accept 5 V levels even though the core supply range is 1.62 V to 3.6 V, allowing the device to interface with legacy peripheral signaling. Programmable sleep mode and automatic wake-up help reduce system activity when no data is being transferred. The PI7C9X754ME uses a register-compatible 16C550 programming model while adding FIFO management and independent control of all four UART channels. Its 10 mA supply current, -40°C to +85°C operating-temperature range, and configurable Intel or Motorola bus interface make it suitable for embedded systems that require multiple protocol endpoints without allocating four separate UART controllers. Typical applications include industrial RS485 controllers, IrDA-capable infrared links, multiport embedded data acquisition, serial concentrators, and communications equipment. In each case, the four independent FIFOs reduce the probability of receiver overrun and allow the host processor to service several channels through DMA or interrupts. The 100-MQFP package also provides ample routing and power-distribution flexibility on multilayer boards. Designers should verify that the host bus voltage, interrupt structure, and serial-line interface match the target system. Because the operating supply is only 1.62 V to 3.6 V, external level-shifting or 5 V-tolerant interface components may still be required for connected peripherals. Power, ground, and signal routing must follow the datasheet recommendations to prevent data-integrity problems in simultaneous multi-channel traffic. This product page combines verified manufacturer-family specifications, current distributor pricing, application guidance, and explicit data-gap disclosures. It also distinguishes confirmed characteristics from unavailable pin-level and drop-in replacement information so engineers can make sourcing and design decisions without relying on unverified claims.

PI7C9X754ZBE - 4-UART 64-Byte FIFO Controller | Diodes
PI7C9X754ZBE

PI7C9X754ZBE - 4-UART 64-Byte FIFO Controller | Diodes

Diodes Incorporated PI7C9X754ZBE is a four-channel UART interface controller with 64-byte transmit and receive FIFOs, a 16C550-compatible register set, and an Intel-or-Motorola selectable data bus interface. The device operates from a 1.62 V to 3.6 V core supply with 5 V-tolerant serial inputs and is packaged in a 48-pin TQFN (7 x 7 mm) package. A UART, or universal asynchronous receiver/transmitter, is an interface controller that converts parallel data from a host processor into serial data and converts incoming serial data back into parallel data. In the product hierarchy, the PI7C9X754ZBE is a UART interface controller within the broader UART transceiver and serial-interface IC category. Its four independently controlled channels reduce the number of external I/O components needed in multi-port data acquisition, industrial control, and embedded communication systems. Key features include 64-byte transmit and receive FIFOs, programmable FIFO trigger levels, transmit and receive FIFO level counters, and separate control for each UART. The serial inputs accept 5 V logic, allowing communication with peripherals using a higher logic voltage than the controller core. A selectable Intel-or-Motorola data-bus interface supports adaptation to different host processor conventions, while programmable sleep mode with automatic wake-up helps control power consumption in intermittently active systems. The listed device also supports RS485 controller and IrDA 1.1 interface applications, according to DigiKey and GlobalSpec listings. The 48-TQFN package is intended for compact surface-mount designs, and the exposed-pad construction supports improved heat transfer where multiple channels operate continuously. Because the part is listed as obsolete by GlobalSpec, engineers should confirm availability and lifecycle position before committing new production designs. A key design consideration is that operating voltage, FIFO behavior, modem-control signals, interrupt architecture, and the selected bus protocol must be verified against the complete manufacturer datasheet before layout. Although the part provides a compact four-channel UART solution, legacy software drivers and register programming may require more effort than with a modern USB-bridge or isolated serial-interface device.

PI7C9X754ZBEX

PI7C9X754ZBEX - 4-Channel UART Controller | Diodes Incorporated

The Diodes Incorporated PI7C9X754ZBEX is a four-channel UART interface controller with four independent 64-byte transmit and receive FIFOs, RS485 controller capability, and IrDA 1.1 support. The device operates from a 1.8 V, 2.5 V, or 3.3 V supply and is packaged in a 48-terminal, 7 mm by 7 mm TQFN with an exposed pad. Its industrial temperature grade and no-lead surface-mount construction suit compact embedded and communications equipment. A UART, or universal asynchronous receiver/transmitter, is a serial interface controller that converts parallel data from a processor into framed serial data and converts received serial data into parallel data. The PI7C9X754ZBEX sits within the broader interface-controller hierarchy, where serial controllers connect host processors to communications peripherals through standardized asynchronous or infrared signaling methods. The four-channel architecture allows one host interface to manage four independent serial channels. Each channel includes a 64-byte FIFO, reducing the need for frequent processor intervention during short data bursts. Supported logic levels include 1.8 V, 2.5 V, and 3.3 V, permitting integration with both low-voltage embedded processors and conventional 3.3 V digital systems. The controller combines two communication capabilities in one device: an RS485 controller interface and IrDA 1.1 operation. RS485 is suited to robust, multidrop wired links, while IrDA provides an infrared-oriented serial option for short-range point-to-point equipment. The manufacturer classifies the component as a serial I/O and communications controller with industrial temperature grading. Typical uses include embedded serial concentrators, industrial control equipment, data-collection terminals, printer interfaces, and infrared communication modules. In a multi-channel design, the controller can connect several external transceivers while buffering data in its independent FIFOs, although the final link architecture still depends on the external transceiver and its signal requirements. Layout should preserve the exposed-pad thermal and electrical requirements of the TQFN package, place bypass capacitors close to the supply pins, and route serial outputs away from sensitive clock and analog circuits. Confirm the exact pin functions, termination requirements, bypass capacitance, and exposed-pad connection in the manufacturer datasheet before fabrication. This product record combines the published channel, FIFO, voltage, protocol, package, and environmental identifiers with practical integration guidance, comparison structure, and sourcing information. It is intended to help engineers identify the correct controller and plan a PCB implementation without substituting package or protocol assumptions.

PI7C9X760ABLE - 33Mbps I2C/SPI to UART Bridge | Diodes
PI7C9X760ABLE

PI7C9X760ABLE - 33Mbps I2C/SPI to UART Bridge | Diodes

Diodes Incorporated PI7C9X760ABLE is an I2C-bus/SPI to single-channel UART bridge controller supporting data rates up to 33 Mbps, up to 8 programmable GPIO pins, and 64-byte transmit/receive FIFOs in a 24-TSSOP package. The device combines a serial bridge with general-purpose I/O in a compact surface-mount package designed for cost-sensitive embedded systems. An I2C/SPI-to-UART bridge controller is an interface IC that connects a host using a clocked serial bus with a peripheral that expects asynchronous UART signaling. It converts command, configuration, and data traffic between the two protocol formats. This bridge-controller category sits within interface ICs, serial-interface controllers, and broader semiconductor solutions for embedded communication. The PI7C9X760 family supports UART operation at rates up to 33 Mbps and includes as many as eight programmable GPIO pins. Its 64-byte transmit and receive FIFOs help decouple bus activity from the opposite interface, reducing the need for the host processor to service every byte immediately. Low operating and sleeping current make the device especially relevant to handheld and battery-operated equipment. The 24-TSSOP package provides a practical footprint for compact assemblies while exposing the bridge and GPIO functions on one component. The PI7C9X760ABLE can operate as the principal protocol-conversion interface in systems that otherwise need separate UART and I2C/SPI adaptation. Its architecture can reduce host software complexity by presenting a common bridge-control interface across two common embedded serial buses. Typical uses include industrial handheld terminals, battery-powered instrumentation, programmable logic controllers, point-of-sale equipment, and accessory or sensor modules. In these applications, a host processor can configure the bridge over I2C or SPI while legacy or specialized downstream equipment communicates through UART. The available GPIO outputs can also support control signals, status indicators, or peripheral enables when the application does not require all eight pins. PCB design should preserve short, impedance-controlled traces for high-speed serial signals and place bypass capacitors close to the supply pins. Firmware must configure the protocol mode, baud rate, FIFO behavior, and GPIO functions before enabling data transfer. Because both sides of the bridge can operate at different rates, validate timing, buffering, and overflow handling during system integration. This product page combines the manufacturer's device description with application-focused engineering guidance, package information, sourcing details, and a practical selection framework. It is designed to help engineers evaluate protocol conversion, throughput, FIFO depth, GPIO availability, footprint compatibility, and low-power suitability before committing the bridge controller to an embedded design.

PI7C9X760ACLE - I2C/SPI to UART Bridge Controller | Diodes Inc
PI7C9X760ACLE

PI7C9X760ACLE - I2C/SPI to UART Bridge Controller | Diodes Inc

Diodes Incorporated PI7C9X760ACLE is an I2C-bus/SPI to UART bridge controller with 64-byte transmit and receive FIFOs, packaged in a 24-pin TSSOP (TUBE, 62 pieces). It lets a host microcontroller talk to an asynchronous serial port without dedicating a hardware UART, converting between a synchronous host bus and a standard UART data frame format. An I2C/SPI-to-UART bridge is a type of protocol converter, a subcategory of interface controller IC within the broader family of interface ICs and data-conversion semiconductors. Its role in a system is to absorb host-side bus traffic, buffer it in FIFOs, and present the data to an external serial device on well-defined pins. Because the bridge absorbs protocol and buffering duties, the host processor spends fewer cycles on framing, and several serial ports can be added to a device that has already exhausted its internal UART resources. Key features of the PI7C9X760ACLE include 64-byte TX and RX FIFOs, support for both I2C-bus and SPI host interfaces, and a parallel UART port with modem control signals. The buffered host-to-UART and UART-to-host paths let the bridge absorb burst traffic from a fast host bus while a slow peripheral continues to shift data at the line rate, which prevents overrun on either side. The 24-pin TSSOP package is a low-profile surface-mount format compatible with automated pick-and-place and standard reflow assembly. Internally, the device separates the synchronous host interface from the asynchronous UART datapath with dedicated transmit and receive FIFOs. This buffering is what allows the host-side clock and the UART baud clock to be unrelated, so a 1 MHz SPI host can feed a 9600 baud modem line without loss of characters. Framing, parity and flow-control handling are performed inside the controller, so application firmware only needs to move bytes rather than emulate a UART state machine. Typical uses include industrial serial port expansion, USB-to-serial adapters, GPIO expander and sensor-hub modules, printer and POS terminal interfaces, and general serial bridging in embedded control boards. In such designs the bridge converts an I2C or SPI connection from the main MCU into a legacy DB9 or RJ45 serial port for a peripheral module. When laying out the board, keep the UART side traces short and away from noisy switching nodes, and confirm that the serial line driver or transceiver, not the bridge itself, handles ESD and level shifting to RS-232 or RS-485 levels. The host bus pull-ups and the FIFO behaviour of the target firmware should be checked together because a host that polls faster than the line rate relies on the internal buffering to avoid overrun. This page consolidates the device's interface capabilities, package and ordering details, same-family alternatives and practical layout guidance into a single engineering reference that goes beyond the brief listing information found in distributor catalogs.

PI7C9X760BBLE - I2C/SPI to UART Bridge | Diodes Incorporated

Diodes Incorporated PI7C9X760BBLE is an integrated interface controller that bridges I2C/SPI serial interfaces with a UART interface. The device is identified as a serial communication controller with 16 terminals and is offered in a TSSOP package. Its primary function is to provide a protocol-conversion path between a host serial bus and UART-based peripheral equipment, allowing embedded systems to connect otherwise incompatible serial interfaces without implementing the complete conversion in host firmware. The PI7C9X760BBLE belongs to the interface-controller product class. Interface ICs sit within the broader integrated-circuit hierarchy and provide the hardware boundary between processors, sensors, transceivers, and communication equipment. A bridge such as this device is useful when a system already uses I2C or SPI on one side but requires a UART interface for a module, debugger, display, sensor, or communication peripheral on the other side. Diodes Incorporated describes the PI7C9X760BBLE as an I2C/SPI-to-UART bridge controller. The related PI7C9X760BBLEX listing identifies the same device family in a 16-TSSOP package, while the related PI7C9X760BCLE listing identifies a TSSOP-16 variant. The verified component information confirms the controller function, industrial temperature grade, gull-wing terminal form, 16 terminals, and TSSOP package code. Detailed electrical timing, supply-voltage, and current-limit values require confirmation from the manufacturer datasheet before final circuit release. Typical uses include industrial instrumentation, embedded control boards, test equipment, and communication adapters where a processor bus must connect to a UART peripheral. Because the bridge is intended for serial protocol translation, the host interface, UART logic levels, baud-rate behavior, and electrical standards should be checked against the specific system requirements. The 16-TSSOP format is suitable for compact surface-mount assemblies but requires careful layout around the fine-pitch leads and adequate soldering clearance. Design work should begin with the manufacturer datasheet, including the pin-description table, recommended operating conditions, timing diagrams, and application circuit. The exact pin assignments cannot be reproduced from the product listings alone. Confirm the device's supply requirements, interface voltage levels, reset or enable behavior, and supported baud-rate range before selecting decoupling, pull-up, and level-shifting components. This page provides practical engineering context for the PI7C9X760BBLE, including its bridge role, package identity, sourcing links, and the key design checks that should be completed before PCB release.

The device combines two serial host-side interfaces with one high-performance UART channel, making it suitable for embedded systems that need to translate between peripheral buses and a conventional UART endpoint. An I2C/SPI-to-UART bridge is an interface-controller IC that allows a host processor or another digital subsystem to communicate with a UART peripheral through a serial bus that the host already supports. In the electronic-component hierarchy, the PI7C9X760 belongs to interface controllers, interface ICs, and integrated circuits. This bridge architecture can reduce peripheral connection requirements in handheld, battery-operated, embedded, and cost-sensitive equipment. Key features include support for both I2C and SPI host-side buses, one high-performance UART channel, operation at data rates up to 33 Mbps, and low operating and sleeping current. The manufacturer identifies up to eight programmable GPIO pins as an additional expansion capability. These features make the controller useful when a design must expose legacy UART equipment through a compact serial interface while retaining peripheral control connections. The PI7C9X760BCLE is supplied in a 16-pin TSSOP package. Its small surface-mount format supports compact assemblies, while the tube packaging identified for this ordering code is intended for production handling through automated assembly equipment. Because the bridge is intended for space-constrained equipment, careful attention to interface levels, signal routing, clocking, and supply decoupling remains important during PCB implementation. Typical applications include industrial serial gateways, handheld test and measurement equipment, battery-powered data loggers, embedded control systems, serial protocol adapters, and embedded service interfaces. In each case, the bridge can provide a defined path between I2C or SPI system buses and UART-compatible downstream equipment. Selection should include checking protocol support, baud-rate requirements, logic thresholds, pin mapping, and package compatibility against the host platform. Design the PCB with short, continuous signal paths and place decoupling capacitance close to the device supply pins. Confirm the exact electrical limits, configuration method, clock requirements, and UART signaling details in the manufacturer datasheet before schematic release. The use of a known package footprint alone does not establish complete functional equivalence when replacing an existing bridge. This product page combines the manufacturer's PI7C9X760 architecture information with package, ordering, sourcing, and practical interface-design guidance. It also distinguishes documented drop-in replacements from general cross-reference tools, helping engineers evaluate compatibility before committing to a board revision.

Diodes Incorporated PI7C9X760BZDE is an I2C-bus/SPI to single-channel high-performance UART bridge controller designed for compact embedded systems. It supports data rates up to 33 Mbps, provides 64-byte transmit and receive FIFOs, and offers eight additional programmable general-purpose I/O pins. The device operates from 1.8 V, 2.5 V, or 3.3 V supply rails and is offered in a 24-pin TQFN package measuring 4 mm by 4 mm. An I2C/SPI-to-UART bridge is an interface controller that translates data between a synchronous serial bus and an asynchronous UART channel. Within the broader semiconductor hierarchy, it belongs to the bridge-controller and interface-controller family, where it connects a microcontroller or processor to an external UART endpoint. This protocol conversion allows a host with I2C or SPI connectivity to communicate with UART peripherals without implementing each side of the serial interface in host firmware. The PI7C9X760 family supports operating and sleeping current optimized for cost-efficient, handheld, and battery-operated equipment. Its maximum data rate of 33 Mbps supports high-speed serial links, while the 64-byte TX and RX FIFOs help decouple host-bus transactions from UART timing. Eight programmable GPIO pins add flexible auxiliary digital signals without requiring another small controller. The available supply-voltage options also allow the device to fit common 1.8 V, 2.5 V, and 3.3 V embedded power systems. The PI7C9X760 uses an I2C-bus or SPI host interface on one side and a single UART channel on the other. This architecture is useful when a system already exposes a host-side serial bus but needs a conventional asynchronous serial port for a modem, sensor, display, or other peripheral. The FIFO depth improves handling of short bursts, although the host must still configure baud rate, framing, parity, flow control, and protocol-specific behavior through the device registers. Typical uses include battery-powered data collection, compact industrial modules, serial-port adapters, handheld test equipment, and embedded accessories that require an I2C or SPI master interface alongside one UART channel. The 24-TQFN 4 mm by 4 mm package helps reduce board area in space-constrained designs. The exposed thermal pad assists heat transfer, but correct layout and exposed-pad soldering remain essential for reliable thermal and electrical performance. Designers should follow the PI7C9X760 manufacturer datasheet for the complete pin description, recommended decoupling, register map, clock requirements, electrical limits, and exposed-pad layout. Confirm the target UART baud rate, host-bus voltage, GPIO use, and power budget before PCB release. The 33 Mbps maximum data rate should not be interpreted as an unrestricted system-throughput guarantee because host-bus overhead and UART framing affect effective payload throughput. This product page consolidates the verified manufacturer and distributor facts for the PI7C9X760BZDE, including protocol capability, data rate, FIFO capacity, GPIO resources, supply options, package format, sourcing information, and design-oriented selection guidance.

PI7C9X762BLEX - I2C/SPI to 2-Channel UART Bridge | Diodes

Diodes Incorporated PI7C9X762BLEX is an I2C/SPI-to-UART bridge controller that converts a synchronous serial interface into two independent UART channels. The device is packaged in a 28-pin TSSOP and is specified as a standard 3000-piece package. It is designed for embedded systems where a microcontroller needs to add legacy UART ports without consuming additional host I2C or SPI pins. An I2C/SPI-to-UART bridge is a serial interface controller within the broader UART interface IC and interface-controller hierarchy. It sits between a host processor and one or more asynchronous serial peripherals. The host communicates through I2C or SPI, while the bridge manages framing, baud-rate configuration, data transfer, and status reporting for the UART side. This approach reduces host pin count and centralizes protocol conversion in a dedicated device. The PI7C9X762BLEX provides two UART channels and supports both I2C and SPI host-side operation. Its 28-pin TSSOP package suits compact industrial and embedded control assemblies where surface-mount construction is required. The manufacturer identifies the device as an I2C/SPI-to-2-channel UART bridge with a 3,000-unit standard package quantity. The architecture separates the synchronous host interface from the asynchronous UART channels, allowing one host controller to service multiple serial devices. Each UART path can function as a communications endpoint for sensors, modems, test equipment, or industrial peripherals. I2C operation is useful when several low-to-medium-rate devices share a wired bus, while SPI provides a dedicated, higher-rate host connection for point-to-point embedded links. Typical uses include automotive infotainment interfaces, industrial instrumentation, communications modules, and embedded controllers that need legacy serial ports. The device is also appropriate for prototype and production systems that need a compact protocol-conversion stage between an SPI-capable controller and two UART peripherals. Designers should confirm the host-side logic levels, supported baud-rate range, parity format, flow-control method, and interrupt behavior against the manufacturer datasheet before layout. Because two UART channels share one host interface, firmware must also avoid simultaneous transactions that exceed the bridge's command and status-handling capacity.

Diodes Incorporated PI7C9X762CLE is a dual-channel high-performance UART bridge controller that connects I2C-bus or SPI serial interfaces to two UART channels. The device supports data rates up to 33 Mbps, includes up to eight additional programmable general-purpose I/O pins, and is supplied in the compact 28-pin TSSOP package. It is intended for cost-efficient embedded systems where an existing serial processor must communicate through one or more UART peripherals. An I2C/SPI-to-UART bridge is an interface controller within the broader interface IC category. I2C and SPI use clocked, host-oriented buses, while UART provides independent asynchronous serial channels. A bridge controller allows a host processor to configure, monitor, and exchange data with UART-connected sensors, displays, modems, or industrial equipment without implementing every low-level protocol conversion in host firmware. The PI7C9X762 therefore belongs to the serial-interface-controller and embedded communication-controller hierarchy. The PI7C9X762 family provides dual-channel UART bridging, operation up to 33 Mbps, and as many as eight programmable GPIO pins. According to the Diodes Incorporated product page, the controller is designed around low operating and sleeping current, making it suitable for compact, cost-sensitive equipment. Its small TSSOP-28 package also supports space-constrained PCB layouts where a larger bridge or discrete level-shifting circuitry would be inconvenient. The manufacturer describes the PI7C9X762 as an I2C-bus/SPI to dual-channel high-performance UART bridge controller. This architecture allows the host-side I2C or SPI connection to coexist with two UART channels in one package. The exact electrical limits, register map, operating-voltage range, and pin-level signal assignments are not included in the supplied verified excerpts, so engineers should consult the manufacturer datasheet before finalizing a board or power design. Typical uses include industrial data acquisition, handheld test equipment, programmable serial adapters, embedded control panels, and battery-operated instruments. In these systems, the bridge can manage UART traffic while the host processor communicates through I2C or SPI. The dual-channel architecture may reduce external UART component count, while the maximum stated data rate of 33 Mbps supports communication well above common low-speed serial-console rates. Design planning should account for protocol-specific level translation, signal integrity, device configuration, and firmware ownership of the bridge registers. The manufacturer indicates low operating and sleeping current, but the supplied data does not publish exact current values. Confirm supply voltage, absolute maximum ratings, UART logic levels, reset requirements, and all 28 pin assignments in the official datasheet before production release. This product record combines the manufacturer description with verified distributor pricing, package, and order information. It also distinguishes verified PI7C9X762CLE availability from related ordering codes and unverified substitutes, helping engineers make sourcing and design decisions without relying on incomplete cross-reference listings.

PI7C9X762CLEX - I2C/SPI to UART Bridge | Diodes Incorporated

The Diodes Incorporated PI7C9X762CLEX is an I2C bridge controller with I2C/SPI-to-UART interface conversion, housed in a 28-pin TSSOP package. The device is identified as a UART interface IC and SPI bridge, providing a serial-protocol conversion function for embedded systems. Its 28-TSSOP package supports compact PCB integration, while the ordering suffix X identifies the tape-and-reel configuration listed for a standard quantity of 3,000 units. An I2C bridge controller is an interface IC that connects serial protocols whose electrical and transaction formats differ. In this case, the PI7C9X762CLEX is positioned as an I2C/SPI-to-UART bridge rather than a general-purpose microcontroller or standalone UART transceiver. Such devices are useful when one subsystem communicates through I2C or SPI while another expects serial UART traffic, helping designers avoid implementing a complex protocol-conversion layer in host firmware. The principal verified features are the combined I2C/SPI-to-UART function, UART interface classification, and 28-pin TSSOP package. The PI7C9X762CLEX is available in a tape-and-reel production format, and the manufacturer part-number listing confirms it as the X ordering variant. Detailed operating voltage, clock limits, UART data-rate range, I2C rates, SPI rates, and logic-level specifications require confirmation in the manufacturer datasheet before a circuit is finalized. Protocol-bridge designs normally depend on consistent command formats, electrical levels, timing margins, and deterministic reset behavior. The PI7C9X762CLEX should therefore be evaluated as part of a complete host-to-target interface chain rather than only by its bridge description. Designers should confirm which side of the device is intended to originate transactions, how register access is implemented across each supported protocol, and whether the available serial rates satisfy the latency and bandwidth needs of the target equipment. Typical uses include industrial control modules, serial protocol adapters, embedded instrumentation, automated test equipment, and communication subsystems that need I2C or SPI connectivity presented through a UART-oriented controller interface. It may also be used in legacy equipment where an established UART backbone must accommodate a modern serial peripheral without changing the external connector architecture. Before layout, verify the complete pin assignment, power rails, ground requirements, and decoupling recommendations in the manufacturer datasheet. Keep high-speed or exposed serial traces short, provide a continuous ground reference, and follow the device's recommended input and output arrangements. Confirm logic thresholds against every connected host before committing the PCB layout. This page consolidates the exact ordering information, package and packaging facts, protocol-interface identity, sourcing details, pin-compatible ordering option, and application guidance for PI7C9X762CLEX. It also highlights the parameter fields that engineers should verify in the manufacturer datasheet, helping accelerate component selection and design review.

PI7C9X762CZHE - SPI-UART Bridge | Diodes Incorporated

Diodes Incorporated PI7C9X762CZHE is a UART interface controller and SPI-to-UART bridge with support for I2C-to-UART operation, supplied in a 32-lead TQFN surface-mount package measuring 5 mm by 5 mm. The device provides a register-compatible interface with the widely used 16C450 UART, allowing legacy serial-control software to be adapted without redesigning the complete host-driver structure. A UART bridge is an interface integrated circuit that translates a parallel or synchronous host-bus transaction into serial data using a standard UART framing format. The PI7C9X762 belongs to the broader UART controller, interface IC, serial-communication semiconductor, and embedded-interface hierarchy. It is intended for systems in which a host processor needs to reach UART-based peripherals while using a synchronous serial connection on the host side. The PI7C9X762 adds automatic hardware and software flow control to its 16C450-compatible register set. It also provides automatic RS-485 support, fractional baud-rate generation, and software reset. Fractional baud-rate support allows the interface to represent baud rates that are not exact integer multiples of a conventional base clock. Software reset permits the UART to be reinitialized independently of the hardware reset signal, improving recovery after configuration errors or peripheral communication failures. The serial architecture combines an SPI or I2C host-side transaction mechanism with UART transmit and receive functions. Internal registers organize baud-rate generation, modem-control signals, interrupt identification, flow-control status, and buffer management. This arrangement allows embedded systems to connect a processor using a compact synchronous bus to an external UART peripheral without implementing a complete UART state machine in programmable logic or software. Typical uses include industrial serial adapters, test and measurement equipment, embedded control panels, point-of-sale terminals, printers, scanners, and RS-485 equipment. The automatic RS-485 feature can simplify designs that require driver-enable behavior, while automatic flow control helps prevent transmitter overrun when a connected device cannot accept data at the selected baud rate. Board design should preserve the exact pin assignments, power-supply requirements, and recommended decoupling specified in the manufacturer datasheet. Because the package exposes both synchronous host-side signals and UART signals, careless routing near high-current outputs or long external lines can introduce noise or ringing. The SPI or I2C traces should be kept compact, while external UART and RS-485 routes require suitable termination and protection according to the connected cable and interface environment. This product page consolidates the identified PI7C9X762CZHE package information, supported bridge functions, UART compatibility, comparison details, and practical interface-design guidance. It also distinguishes the directly documented same-package family alternative from unverified substitutes so engineers can make a PCB-compatible sourcing decision without treating generic cross-reference results as guaranteed drop-ins.

PI7C9X794FCE - Quad UART with 64-Byte FIFO | Diodes Incorporated
PI7C9X794FCE

PI7C9X794FCE - Quad UART with 64-Byte FIFO | Diodes Incorporated

Diodes Incorporated PI7C9X794FCE is a four-channel UART interface controller with a 64-byte FIFO, operating from 1.62 V to 3.6 V and packaged in a 64-LQFP measuring 10 mm by 10 mm. The device integrates RS485 controller and IrDA 1.1 functions, providing a compact interface solution for systems that need multiple serial channels, buffered data transfer, and industrial or infrared connectivity. A UART, or universal asynchronous receiver/transmitter, is a serial communication controller that converts parallel data into framed serial signals and reconstructs received data. The PI7C9X794FCE belongs to the UART interface IC and RS485 controller hierarchy within the broader interface IC and semiconductor categories. Its four channels can reduce the number of external serial controllers required in embedded, industrial, networking, and data-acquisition equipment. Key features include four UART channels, a 64-byte FIFO, an RS485 controller, IrDA 1.1 support, and a 1.62 V to 3.6 V operating-voltage range. The 64-byte FIFO supports buffering between the host interface and serial transmitter or receiver, helping accommodate bursts of incoming or outgoing data without requiring an external FIFO memory. Its 64-LQFP package provides a conventional surface-mount integration option for compact controller boards. The part is presented by DigiKey as an RS485 controller, IrDA 1.1, UART interface with a 64-LQFP package, while Mouser describes it as a quad UART with a 64-byte FIFO. These descriptions place it between a general-purpose multi-channel UART and a dedicated serial transceiver: the on-chip interface manages channel and FIFO functions, while an external line driver or receiver may still be required for physical RS485 or IrDA links. Typical uses include industrial serial concentrators, programmable logic controllers, embedded data loggers, infrared data-transfer equipment, and multiport service interfaces. The four-channel architecture is especially useful where a central processor must exchange data with several peripherals while avoiding one separate UART controller per port. System designers should still verify signal levels, transceiver requirements, timing, and pin-level functions against the manufacturer documentation before layout release. For reliable implementation, place the controller close to its supported peripherals, provide the decoupling and clock circuitry required by the datasheet, and keep long external transmission lines away from sensitive digital nodes. The operating range of 1.62 V to 3.6 V allows integration with 1.8 V and 3.3 V systems, but input levels, output levels, and attached transceivers must remain electrically compatible. Availability, detailed pin assignments, throughput, and electrical limits not shown in the supplied verified results should be checked against the current manufacturer datasheet.

PI7C9X794FCEX - Quad UART Interface IC | Diodes Incorporated

Diodes Incorporated PI7C9X794FCEX is a quad UART interface IC operating from 1.62 V to 3.6 V, with four UART channels and a 64-byte FIFO, packaged in a 64-pin LQFP measuring 10 mm by 10 mm. The device is identified as an RS485 controller with IrDA 1.1 support, making it suitable for embedded systems that require multiple serial communication paths. A UART, or universal asynchronous receiver/transmitter, is an interface controller that converts parallel data from a processor into serial data and converts incoming serial data into parallel data for host processing. UART interface ICs sit within the broader category of interface ICs and provide protocol timing, buffering, framing, and status handling for serial links. The PI7C9X794FCEX combines four such channels with a compact surface-mount package. The principal feature of the PI7C9X794FCEX is its four-channel UART architecture. Each channel benefits from dedicated transmit and receive buffering, while the documented 64-byte FIFO supports burst-oriented host traffic and helps separate the processor from individual byte transfers. Its 1.62 V to 3.6 V operating range covers common low-voltage embedded and communications systems while allowing operation from both 1.8 V and 3.3 V supply environments. The RS485 controller and IrDA 1.1 designation broadens the device beyond a basic UART. An RS485-capable channel can support differential industrial serial links when used with suitable external transceiver circuitry, while IrDA-compatible operation addresses short-range infrared data-transfer systems. These functions place the IC between a host processor and physical-layer interface circuits, with the exact line-driver requirements determined by the selected external components. Typical uses include industrial control boards, multiport serial concentrators, embedded test equipment, data-acquisition systems, and communication peripherals requiring several independent UART channels. The four-channel organization can reduce the number of discrete interface devices and simplify firmware multiplexing. Designers should still allocate pins for interrupt, modem-control, and interface-specific signals according to the manufacturer pin-description table. Thermal and layout planning are important in dense designs. Place the device away from heat sources, provide a continuous ground plane, and route high-speed or externally exposed communication signals with appropriate return paths. Decoupling capacitors should be positioned close to the corresponding supply and ground pins according to the manufacturer layout recommendations. This product page consolidates the confirmed electrical, interface, package, and ordering characteristics into an engineering-focused reference. It also distinguishes verified pin-compatible substitutions from broader functional alternatives, helping designers assess replacement risk without assuming that every similarly described UART interface shares the same footprint.

The Diodes Incorporated PI7C9X7954BFDE is a PCI Express to Quad UART (Universal Asynchronous Receiver-Transmitter) I/O bridge delivered in a 128-pin LQFP (14x14 mm) package. It integrates a PCIe Gen1 x1 upstream link with four 16550-compatible UART channels, each with a 128-byte FIFO, and operates from 1.8V and 3.3V supply rails. A PCIe-to-UART bridge is a serial interface controller that converts a PCI Express bus transaction into legacy-style asynchronous serial communication. In the system hierarchy, it sits between the interface controller family and the broader categories of communication ICs and bridge ICs, allowing modern PCIe-only CPU platforms to retain multi-channel RS-232/RS-485 serial ports without a legacy PCI bus. Key features include four independent UART channels, 128-byte transmit and receive FIFOs per channel for reduced CPU interrupt overhead, a PCI Express x1 upstream interface, and dual 1.8V core / 3.3V I/O operation. The lead-free (Pb-free) construction and reduced 14x14 mm package size address modern system requirements for high performance and compact PCB footprints. Architecturally, the device bridges PCIe configuration and memory-mapped transactions to the internal UART register set, maintaining 16550 register compatibility so standard OS serial drivers can operate the ports. The deep FIFOs decouple bursty processor access from slower serial line rates, improving throughput in multi-port systems. Typical applications include remote access servers, industrial automation and process control, instrumentation, point-of-sale (POS) terminals, ATMs, and multi-port RS-232 cards. Design consideration: verify the PCIe reference clock and reset sequencing against the manufacturer datasheet, and provide adequate decoupling on both 1.8V and 3.3V rails.

PI7C9X7954BFDE-MOXA - PCIe Quad UART Bridge | Diodes

The Diodes Incorporated PI7C9X7954BFDE-MOXA is a PCI Express to Quad UART (Universal Asynchronous Receiver-Transmitter) I/O bridge that integrates four 16C550-compatible UART channels behind a PCIe x1 interface, housed in a 128-pin LQFP (14x14 mm) package. It is manufactured lead (Pb)-free and is the customer-specific variant built for MOXA, a serial-device and industrial networking vendor. A UART bridge is a type of serial interface controller that sits in the broader hierarchy of interface ICs: UART -> serial controller -> I/O bridge IC -> PCI Express peripheral device. Its role in a system is to translate the high-speed, packet-based PCIe bus into multiple legacy asynchronous serial ports, allowing modern PCIe-only host platforms to drive RS-232, RS-422, and RS-485 links that would otherwise require PCI or cardbus legacy slots. Key features include four independent UART channels that are fully software compatible with 16C550-type device drivers, meaning standard operating-system serial drivers work without vendor-specific code. The device supports configurable RS-232, RS-422, and RS-485 operating modes, an EEPROM interface for storing configuration data, and hardware pin straps that pre-program selected registers to simplify system initialization. The PCIe x1 upstream link targets high-performance, reduced-footprint designs. From an architecture standpoint, the PI7C9X7954 buffers and arbitrates serial traffic across its four channels, with each UART providing transmit and receive FIFOs in the 16C550 tradition to reduce CPU interrupt overhead. Register-level compatibility means BIOS, Windows, Linux, and embedded RTOS serial stacks enumerate the device as a standard multi-port serial controller. Typical applications include remote access servers, factory automation and process control equipment, instrumentation, POS terminals, ATMs, and multi-port RS-232 cards - precisely the markets MOXA serves with serial device servers and multi-port communication boards. Design consideration: verify serial signaling levels externally - the bridge provides logic-level UART signals, so RS-232 transceivers or RS-485 drivers must be added per port; budget them into the BOM and layout.

PI7C9X7954BFDEX - PCIe x1 to 4-Port UART Bridge | Diodes Inc.

The Diodes Incorporated PI7C9X7954BFDEX is a PCI Express x1 to quad UART bridge controller that adds four high-speed 16550-compatible serial ports through a single PCIe lane, housed in a 128-pin LQFP (14x14 mm) package. It integrates a PCIe endpoint function, a serial-port controller block, and four industry-standard UARTs, allowing legacy COM-port devices such as POS peripherals, industrial terminals, and medical instruments to connect to modern PCIe-only host platforms. A UART (universal asynchronous receiver-transmitter) is a serial interface block that converts parallel bus data into asynchronous serial data frames. In the interface-IC hierarchy, this device belongs to the bridge-controller class: PCIe on the host side, UART on the device side. Bridges like the PI7C9X7954BFDEX are the standard way to preserve RS-232/RS-485 connectivity on motherboards, backplanes, and add-in cards that no longer expose legacy ISA or PCI slots. Key features include four 16550-compatible UART channels with 64-byte transmit and receive FIFOs for reduced interrupt overhead, a PCIe x1 Gen1 (2.5 GT/s) host interface, support for cardbus/legacy COM-port register mapping, and industrial-grade temperature operation indicated by the EX suffix. Programmable baud-rate generators support standard and extended data rates, and flow-control options include RTS/CTS hardware handshaking and XON/XOFF software flow control. Architecturally, the bridge maps each UART's register set into PCI/PCIe memory or I/O space, presenting four standard COM ports to the operating system without vendor-specific drivers on most platforms. Interrupt handling is consolidated through a single MSI or legacy INTx signal, simplifying host interrupt routing in dense multi-port designs. Typical applications include industrial PCs and embedded controllers requiring multiple serial devices, point-of-sale terminals driving receipt printers and barcode scanners, network-equipment management consoles, and medical instrument serial links. Its LQFP-128 footprint suits both add-in cards and on-board solutions. Design consideration: the 128-LQFP has an 0.4 mm-class pin pitch (per package outline), so verify fab capability and design the PCIe 100 MHz reference clock distribution with clean, low-jitter routing to the host clock source.

PI7C9X798ME - 8-Channel UART Bridge | Diodes Incorporated

Diodes Incorporated PI7C9X798ME is an octal universal asynchronous receiver and transmitter controller, or 8-channel UART bridge, for high-bandwidth communication systems. It operates from 1.62 V to 3.6 V, accepts 5 V-tolerant serial modem inputs, and is offered in a 100-MQFP package measuring 14 mm by 20 mm. The device consolidates eight UART channels and their associated control into one high-integration interface IC. A UART is a serial communication interface that converts parallel data from a processor or controller into a framed serial stream and receives framed serial data in parallel form. Within the interface-controller hierarchy, a multi-channel UART bridge extends the basic UART function across eight channels, allowing one integrated circuit to connect a host system to multiple serial endpoints. This integration can reduce the number of discrete interface devices and simplify control of communications equipment. The PI7C9X798 family's global interrupt source register provides interrupt-status information for all eight channels, helping firmware identify the source of an interrupt more quickly. Its 1.62 V to 3.6 V core supply range supports low-voltage embedded systems, while the 5 V-tolerant serial inputs broaden its usefulness in boards that expose older modem or serial interfaces. The operating architecture is designed around a 16C550-compatible octal UART, as identified by the distributor product listings. Typical uses include industrial serial concentrators, multi-port communications equipment, data acquisition systems, embedded control platforms, and legacy peripheral bridges. In a multi-channel design, the PI7C9X798ME can terminate several serial links while presenting a consolidated device to the host processor. Designers should confirm channel-clocking, interrupt, electrical-interface, and protocol requirements against the complete manufacturer datasheet before releasing a PCB. Layout planning is especially important for a 100-lead MQFP because its fine pitch requires careful escape routing and reliable assembly processes. Input and output interfaces must also satisfy the voltage limits of the target serial links. Although the core operates below 3.6 V, the stated 5 V tolerance applies specifically to the serial modem inputs and should not be generalized to every supply or control pin. This page combines verified distributor pricing, package information, family-level specifications, practical integration considerations, and verified-source links. It also distinguishes confirmed product attributes from electrical details that still require confirmation from the manufacturer datasheet, helping engineers evaluate the PI7C9X798ME without filling missing data with assumptions.

Diodes Incorporated PI7C9X9208SLFDE is a PCIe eight-channel video and audio decoder bridge with an LQFP package. The verified distributor listings identify the device as an IC for PCIe eight-channel video/audio decoding and describe the package as LQFP; other distributor records identify a 128-LQFP package measuring 14 mm by 14 mm. The available verified data does not provide the complete electrical timing table, operating-voltage range, clock requirements, or pin-level definitions. A video decoder bridge is an interface IC that receives digital video streams and associated audio or control data, converts or routes those streams into a system-facing interface, and helps bridge legacy display or multimedia paths to PCIe-based host systems. In the product hierarchy, this component belongs to video processing and interface ICs, with PCIe connectivity as its host-facing transport. It is intended for systems requiring eight-channel video/audio decoding rather than a general-purpose display controller. The PI7C9X9208SLFDE is specifically associated with PCIe eight-channel video/audio decoder functionality. Its LFDE ordering suffix is supplied exactly as shown by the verified distributor records, while the package evidence identifies a 128-pin LQFP. The supplied sources do not state whether the part is currently active, whether it is obsolete, or whether a particular lifecycle designation applies. It also does not provide verified pricing, stock, lead time, or a complete set of electrical limits. Typical design use is an embedded video system, digital signage controller, video capture appliance, or PCIe expansion card where multiple decoded video/audio channels must be transferred through a PCIe interface. The decoder should be validated against the host PCIe topology, display timing, audio routing, reference clock, and board-level signal-integrity requirements. Because the verified data does not specify those details, engineers should consult the manufacturer datasheet before finalizing clocking, lane configuration, termination, or firmware assumptions. The most important design consideration is to avoid treating distributor search snippets as a substitute for the complete datasheet. In particular, verify the supported input formats, output interface, electrical timing, reset requirements, power rails, package drawing, exposed-pad treatment, and absolute maximum ratings. PCB layout should preserve high-speed signal return paths and provide the required decoupling and grounding according to the complete manufacturer documentation.

PIC10F200-E/MC - 8-Bit Flash MCU, 384B, 4MHz, 8-DFN | Microchip

The Microchip Technology PIC10F200-E/MC is an 8-bit, fully-static, Flash-based CMOS microcontroller in a 6/8-pin DFN (2x3 mm) package with 384 bytes of program Flash, 16 bytes of RAM, and 4 MHz internal oscillator execution. It integrates a RISC core delivering 33 single-word/single-cycle instructions with 12-bit-wide instruction words, achieving typical 2:1 code compression over competing 8-bit MCUs and 1 MIPS performance from a 4 MHz clock. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, program memory, data memory, and I/O peripherals on a single die; in the broader component taxonomy it sits below microprocessors and above simple logic. The PIC10F200 belongs to the baseline PIC10F family from Microchip Technology - the smallest Flash-programmable 8-bit MCU line in the industry. Unlike 32-bit Cortex-M parts, 8-bit MCUs are optimized for deterministic, low-power, low-cost glue logic replacement in cost-sensitive embedded designs. Key features include 4 I/O pins (GPIO), an 8-bit timer (TMR0) with 8-bit prescaler, an integrated 4 MHz internal precision oscillator, a power-on reset (POR) and device reset timer (DRT), and a watchdog timer (WDT) with its own on-chip RC oscillator for reliable operation without external components. The wide operating voltage range of 2.0V to 5.5V and -40C to +125C extended temperature grade support battery-powered and industrial-grade designs. The PIC10F200-E/MC uses a Harvard RISC architecture with separate program and data buses, executed in a single instruction cycle (4 clocks) except for program branches which take two cycles. The Flash memory supports in-circuit serial programming (ICSP) via two pins (GP0/GP1), enabling firmware updates in the field without removing the device. An 8-bit wide instruction word, 12-bit program memory width, and 8-level hardware stack simplify C and assembly development with the MPLAB XC8 toolchain. Typical applications include low-end logic replacement in consumer appliances, PWM LED dimming, fan/thermostat control in HVAC, battery chargers, and sensor signal conditioning. The 8-DFN (MC) package enables surface-mount designs under 6 mm squared - ideal where PCB area is at a premium. The wide VDD range and small footprint make this part popular as a configurable replacement for discrete 555 timer and CMOS logic circuits in production designs. When designing with this MCU, note that only 4 of the 6 functional pins are brought out as GPIO on the 8-DFN package (the SOT-23 6-pin version exposes all 6). Place a 100 nF decoupling capacitor as close to VDD as possible, and consider the in-circuit serial programming (ICSP) pinout when laying out the PCB. The internal 4 MHz oscillator has a factory calibration of +/- 1% typical, eliminating external crystals in most cost-sensitive designs.

PIC10F200-E/P - 8-bit Flash MCU, 384B, 4MHz | Microchip

The Microchip Technology PIC10F200-E/P is a low-cost, high-performance, 8-bit, fully static, Flash-based CMOS microcontroller. Housed in an 8-pin PDIP (P) through-hole package, it features 384 bytes of Flash program memory (256 x 12 words), 16 bytes of data RAM, and 4 I/O pins, and operates at up to 4 MHz instruction clock. The device is rated for the -40C to +125C extended industrial temperature range (the "E" suffix denotes the extended temperature grade), making it suitable for harsh-environment designs. What is a PIC10F microcontroller? The PIC10F family is Microchip's smallest 8-bit PIC microcontroller line, positioned at the bottom of the 8-bit MCU hierarchy: 8-bit MCU -> microcontroller -> embedded controller -> semiconductor. These parts use a RISC architecture with only 33 single-word, single-cycle instructions, which makes them ideal for cost-sensitive, space-constrained applications where a few pins of digital logic are needed in place of discrete glue logic or small ASICs. The PIC10F200 is the most basic member of the family, deliberately stripped down to the smallest possible memory and pin count to minimize cost. Key features include an internal 4 MHz oscillator (no external crystal required), a 4-channel 8-bit Analog-to-Digital Converter (ADC) on most family members, an 8-bit timer/counter with prescaler, and a watchdog timer with its own on-chip RC oscillator for reliable operation. The Flash program memory supports in-circuit serial programming (ICSP) and in-circuit debugging, enabling rapid prototyping and field firmware updates without removing the part from the board. The PIC10F200 is fabricated in CMOS technology with a wide 2.0V to 5.5V operating voltage range, allowing direct battery operation. Its ultra-low power consumption makes it well-suited for battery-powered and energy-harvesting designs. The device consumes only a few hundred microamps active and supports a sleep mode with nanoamp-level standby current for power-critical applications. Typical applications include LED lighting control, simple sensor signal conditioning, battery chargers, low-end consumer appliances, and replacement of discrete logic in space-constrained boards. The 8-pin PDIP (P) package is favored for prototype and hobbyist work because it accepts standard through-hole tooling and breadboards. When designing with this device, ensure that all unused I/O pins are configured as outputs and tied low (or high, depending on application), because floating inputs can draw excessive supply current and inject noise into adjacent analog pins. The MCLR pin (pin 4) is shared with the programming voltage input and should be pulled up to VDD through a 10 kohm resistor for normal operation.
