PI7C9X1170BBLEX

Controllers Overview

The PI7C9X1170BBLEX 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-byte transmitter and receiver FIFOs to enhance data throughput and reduce CPU overhead. It operates at nominal voltages of 1.8V, 2.5V, and 3.3V and is housed in a TSSOP-24 package.

Controllers Feature Summary

• Supports I2C and SPI master/slave interface protocols for system connectivity
• Integrates 64-byte TX and RX FIFOs to minimize processor intervention
• Fully compatible with industrial standard 16C450 UART functionality

Controllers Applications

• Embedded systems requiring serial-to-UART conversion
• IoT devices utilizing low-pin-count interfaces
• Industrial control equipment with limited GPIO availability

Controllers Procurement Notes

Verify the specific suffix 'BBLEX' against the official datasheet to confirm voltage range and packaging details. Confirm RoHS compliance status and check for End-of-Life notices from Diodes Incorporated before finalizing procurement plans.

Controllers Selection Notes

Select this component when a design requires converting I2C or SPI buses to UART without dedicated microcontroller pins. Ensure the host system supports the required clock speeds and voltage levels compatible with the 1.8V/2.5V/3.3V operation.

Controllers Part Context

This part belongs to the PI7C9X1170 family of UART bridge controllers. It shares functional similarities with other variants like the PI7C9X1170ACLEX but may differ in electrical specifications or packaging based on the manufacturer's suffix coding conventions.

Controllers Replacement Considerations

The PI7C9X1170ACLEX is a documented variant within the same product family. Verify pinout compatibility and electrical parameters before substitution.
