PI7C9X754FCEX

Controllers Overview

The PI7C9X754FCEX is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by Diodes Incorporated. It integrates four independent UART channels, each equipped with a 64-byte first-in-first-out (FIFO) buffer to enhance data throughput and reduce processor overhead. The device operates within a supply voltage range of 1.62V to 3.6V and supports standard serial communication protocols. It is housed in a 64-lead Low Profile Quad Flat Package (LQFP-64) designed for surface-mount technology applications.

Controllers Feature Summary

• Integrates four independent UART channels with dedicated 64-byte FIFO buffers per channel
• Supports wide operating supply voltage range from 1.62V to 3.6V
• Designed for surface-mount installation in compact LQFP-64 packages

Controllers Applications

• Industrial control systems requiring multiple serial communication links
• Embedded computing platforms needing expanded UART connectivity
• Telecommunications equipment utilizing serial data interfaces

Controllers Procurement Notes

Verify the specific suffix 'EX' against official Diodes Incorporated documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the LQFP-64 package. Confirm RoHS compliance status through current datasheets before integration into final assemblies.

Controllers Selection Notes

Select this component when multiple isolated UART interfaces are required within a single footprint. The integrated FIFOs minimize CPU intervention during high-speed serial transfers. Verify that the target system voltage aligns with the 1.62V to 3.6V operational range for reliable signal integrity.

Controllers Part Context

This part belongs to the PI7C9X754 family of UART interface ICs from Diodes Incorporated. Variants such as the PI7C9X754FCE share similar functional characteristics but may differ in packaging or environmental ratings. The FCEX designation typically indicates specific manufacturing or packaging configurations within this product line.

Controllers Replacement Considerations

Direct replacements include other quad UART ICs with comparable FIFO depths and voltage ranges. Verify pin-to-pin compatibility if substituting with devices from other manufacturers. Ensure thermal performance and package dimensions match the original design constraints.
