PI7C9X760ACLE

Controllers Overview

The PI7C9X760ACLE is a single-channel I2C-bus/SPI to UART bridge controller manufactured by Diodes Incorporated. It supports I2C fast speed or SPI mode 0 interfaces, with SPI clock speeds up to 33 Mbit/s. The device features 64-byte transmitter and receiver FIFOs, programmable trigger levels, and baud rates up to 16 Mbit/s using a 4X sampling clock rate. It operates at 1.8V, 2.5V, or 3.3V and includes up to eight user-programmable GPIO pins. The internal register set is fully compatible with the industrial standard 16C450.

Controllers Feature Summary

• Supports bidirectional protocol conversion from I2C-bus or SPI to RS-232/RS-485/RS-422
• Includes automatic hardware and software flow control with programmable Xon/Xoff characters
• Features built-in IrDA encoder and decoder interface supporting SIR speeds up to 1.152 Mbit/s
• Provides software reset capability independent of hardware reset signals

Controllers Applications

• Industrial Computing
• Automation
• Factory Process Control
• Mobile Computing
• Embedded Applications

Controllers Procurement Notes

Verify the specific package variant against the datasheet, as the base model PI7C9X760 is available in multiple packages including TQFN-24. Confirm that the ordering suffix corresponds to the required tape and reel quantity and temperature range specifications for your production environment.

Controllers Selection Notes

Select this component when a low-power, small-footprint UART bridge is needed for battery-operated devices. Ensure the host system supports either I2C or SPI slave modes, as the device does not support master functionality. Verify that the required baud rates align with the available crystal frequencies listed in the datasheet tables.

Controllers Part Context

The PI7C9X760 belongs to Diodes Incorporated's family of I2C/SPI to UART bridge controllers. It serves as a cost-effective solution for adding serial communication capabilities to systems with limited parallel bus resources. The device is designed to replace traditional UARTs while offering enhanced flexibility through programmable GPIOs and advanced flow control features.

Controllers Replacement Considerations

The PI7C9X760 is functionally backward-compatible with the 16C450 UART. Designers migrating from legacy UARTs should verify register mapping compatibility. No direct pin-to-pin replacement part numbers are officially documented for this specific package configuration.
