L9663 Description

The Peripheral Sensor Interface (PSI5) is an interface for automotive sensor applications. PSI5 is an open standard based on existing sensor interfaces for peripheral sensors and offers a universal and flexible solution for multiple sensor applications. The PSI5 interface allows asynchronous or synchronous operations and different bus modes.
