Diodes’ low-power I2C/SPI bus to dual-channel UART bridge enhances automotive connectivity robustness
2025-10-16

Dior (Nasdaq: DIOD) announced the launch of PI7C9X762Q, a high-performance I2C/SPI bus to dual channel UART bridge that meets automotive standards. This device has low power consumption in both working and sleep modes, making it very suitable for electric vehicle (EV) design. The main application areas include intelligent cockpits, central controllers, I/O module controllers, advanced driver assistance systems (ADAS), remote information processing, and regional gateways.

PI7C9X762Q provides complete bidirectional protocol conversion and supports SPI clock speeds of up to 33Mbps. UART includes a 64 byte TX/RX FIFO with programmable trigger levels and supports programmable character formats, including 5-bit, 6-bit, 7-bit, or 8-bit characters; Even, odd, or non even; 1. 1.5 or 2 stop positions. The internal register set of this device is backward compatible with equivalent UART on the market, which can simplify software development and migration.

The UART bridge adopts a very compact 32 contact TQFN package, with a size of 5mm x 5mm, integrating up to eight programmable and general-purpose I/O (GPIO) pins, providing flexible design options. The device also offers advanced features, including automatic hardware and software flow control, providing a stable, safe, and cost-effective solution for robust interconnection. Other features include support for decimal baud rate and software reset function that allows UART to be reset at any time without being affected by hardware reset signals.

We also provide a standard compliant version PI7C9X762, suitable for industrial and commercial applications.
