PI7C9X762CLEX

Controllers Overview

The PI7C9X762CLEX is a dual-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts I²C-bus or SPI protocols to RS-232/RS-485/RS-422 serial interfaces. The device supports baud rates up to 16 Mbit/s with a 4X sampling clock 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 are 1.8V, 2.5V, or 3.3V, with an industrial temperature range of -40°C to 85°C. It includes up to eight programmable GPIO pins and is housed in a 32-pin TQFN package.

Controllers Feature Summary

• Dual-channel full-duplex UART interface with backward compatibility to the 16C450 register set
• Support for I²C-bus fast speed slave mode and SPI mode 0 with clock speeds up to 33 Mbit/s
• Integrated 64-byte TX/RX FIFOs with programmable trigger levels to reduce host software overhead
• Advanced flow control including automatic hardware RTS/CTS and programmable Xon/Xoff software flow control

Controllers Applications

• Industrial Computing
• Automation and Factory Process Control
• Mobile Computing and Embedded Applications
• Battery Operated Devices
• Networking Equipment

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance and halogen-free status requirements with the supplier. Ensure the selected variant matches the required interface configuration and voltage levels for the target application environment.

Controllers Selection Notes

Select this component when a bidirectional protocol bridge between I²C/SPI masters and UART peripherals is required. It is suitable for applications needing high data rates up to 33 Mbps on the SPI interface. Consider the 64-byte FIFO depth for buffering requirements and the availability of GPIO pins for additional system control functions within the compact QFN package.

Controllers Part Context

The PI7C9X762 belongs to the SC16IS750/760 family of UART bridge controllers from Diodes Incorporated. It shares functional similarities with other devices in the series but offers specific pin configurations and interface options. The CLEX suffix typically denotes a specific packaging and reel configuration for surface-mount assembly.

Controllers Replacement Considerations

Direct replacements include the PI7C9X760BCLE and PI7C9X762BZHE, though package differences exist. Verify register compatibility and pinout alignment before substitution. Consult Diodes Incorporated for automotive-grade alternatives like the PI7C9X762Q if AEC-Q100 qualification is required.
