PSI5 IP Core Controller for Peripheral Sensor Interface 5 Communication

Overview

The DPSI5 is a hardware implementation of a controller for the Peripheral Sensor Interface (PSI5) protocol. This controller complies with the PSI5 protocol specification V2.3 and is designed for use in electronic control units (ECUs) to ensure communication with up to six sensors.

Data transmission from the sensor to the ECU is achieved through current modulation on the power supply line, with a data rate of 125 kbit/s or 189 kbit/s, using a Manchester decoder. Data transmission from the ECU to the sensor is performed via voltage modulation on the power supply.

The DPSI5 supports operation in asynchronous or synchronous mode and accommodates a wide range of sensor data word lengths (8 to 28 bits). It also provides message verification using either a CRC checksum or bit parity.
