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.
The device is compatible with both v1.3 and v2.1
PSI5 revisions (limitations are specified inside this
document). It operates with a wide range of
sensor supply current and variable data word
length (8 to 28 bit).
The sensors are connected to the ECU using the
same line for power supply and data
transmission. The transceiver IC provides a pre-
regulated voltage to the sensors and reads in the
transmitted sensor data.
The PSI5 interface allows either point to point
connection or bussed mode.
