PI7C9X762BZHEX

Controllers Overview

The PI7C9X762BZHEX is a dual-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts data between I2C-bus/SPI interfaces and serial protocols like RS-232/RS-485. The device supports baud rates up to 16 Mbit/s with a 4X sampling clock rate and SPI clock speeds up to 33 Mbit/s. It features 64-byte transmitter and receiver FIFOs, programmable character formatting (5-8 bits, parity, stop bits), and hardware/software flow control. Operating voltages include 1.8V, 2.5V, and 3.3V within an industrial temperature range of -40°C to 85°C. It is housed in a 32-pin TQFN package.

Controllers Procurement Notes

Verify the specific suffix BZHEX against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm availability status as distribution channels may vary. Validate that the operating voltage and temperature ranges align with your system design constraints before finalizing procurement orders.

Controllers Selection Notes

Select this component when a bidirectional protocol bridge from I2C or SPI to UART is required. It is suitable for applications needing low standby current and small form factors. Consider the 32-pin TQFN package for space-constrained designs. Verify that the host system can support the required SPI clock speed or I2C bus speed for optimal performance.

Controllers Part Context

The PI7C9X762 belongs to the PI7C9X76x series of UART bridge controllers. This family provides versatile connectivity solutions for converting parallel bus data to serial formats. The device integrates advanced features like software reset and fractional baud rates, distinguishing it from standard UART implementations while maintaining register compatibility with legacy 16C450 designs.
