PI7C9X760BZDE

Controllers Overview

The PI7C9X760BZDE is a single-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts I2C or SPI serial interfaces to standard UART signals, supporting baud rates up to 16 Mbit/s with 4x sampling. The device integrates 64 bytes of transmitter and receiver FIFOs to enhance data throughput and reduce CPU overhead. It operates at nominal supply voltages of 1.8 V, 2.5 V, and 3.3 V, with a maximum SPI clock speed of 20 Mbit/s in slave mode. Packaged in a 24-pin TQFN (4x4 mm) format, it is fully compatible with the industrial standard 16C450 UART.

Controllers Feature Summary

• Supports I2C bus and SPI interface protocols for system connectivity
• Integrates 64-byte TX and RX FIFOs for efficient data buffering
• Provides full-duplex UART communication with high-speed baud rate support

Controllers Applications

• Embedded systems requiring serial-to-parallel conversion
• IoT devices utilizing low-power microcontrollers
• Industrial control panels needing reliable UART bridging

Controllers Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors. Confirm package marking and date codes against official specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Review datasheet revisions for any functional updates or pinout changes before finalizing procurement orders.

Controllers Selection Notes

Select this component when an I2C or SPI master needs to communicate with legacy UART peripherals. It serves as a drop-in replacement for the 16C450 in designs requiring lower voltage operation. Consider the 24-TQFN package constraints for PCB layout. Verify that the host controller supports the required SPI modes or I2C speeds for optimal performance.

Controllers Part Context

This part belongs to the PI7C9X760 family of UART bridge controllers from Diodes Incorporated. It shares functional similarities with other models in the series but differs in package type and channel configuration. The ZDE suffix indicates a specific tape-and-reel packaging variant within the broader product line.

Controllers Replacement Considerations

The PI7C9X760CZDEX is listed as a direct replacement for the PI7C9X760BZDE. Both components offer identical functionality and pinouts, allowing for straightforward substitution in existing designs without hardware modifications.
