PI7C9X762CLE

Controllers Overview

The PI7C9X762CLE is a dual-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts I²C-bus or SPI interfaces to RS-232/RS-485/RS-422 serial data. The device supports SPI clock speeds up to 33Mbps and I²C fast speed. It features 64-byte transmitter and receiver FIFOs with programmable trigger levels. Operating voltages include 1.8V, 2.5V, and 3.3V. The component operates within an industrial temperature range of -40°C to 85°C. It is housed in a 28-TSSOP package.

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 status and lead-free green device definitions prior to procurement. Ensure the selected variant matches the required interface configuration for the target application design.

Controllers Selection Notes

Select this component when a bidirectional protocol bridge between I²C/SPI and UART is required. Verify that the host system supports the necessary SPI mode or I²C slave addressing. Check that the available GPIO pins meet the project requirements for modem control signals or general purpose usage.

Controllers Part Context

This part belongs to the PI7C9X76x series of UART bridge controllers from Diodes Incorporated. The family includes variants such as the PI7C9X762Q for automotive applications and other packages like TQFN. The CLE suffix typically denotes the commercial grade version in a specific surface-mount package format.

Controllers Replacement Considerations

The SC16IS750/760 series shares functional similarities but may differ in pinout or electrical characteristics. Verify register compatibility and physical footprint before substitution. Consult official cross-reference guides for confirmed equivalent parts.
