PSI5-HOST Peripheral Sensor Interface (PSI5) Host Controller

Computer Aided Software Technologies, Inc (dba CAST)

Member

The PSI5-HOST IP core is a configurable automotive Peripheral Sensor Interface (PSI5) host controller that implements the ECU side of PSI5 communication systems. The core supports PSI5 Specification v2.3 and is backward compatible with PSI5 v1.3.

PSI5-HOST enables robust communication between ECUs and automotive sensors using low-cost two-wire communication over sensor power lines.

The core supports both synchronous and asynchronous modes, ECU-to-sensor downstream communication using tooth-gap or pulse-width encoding, and sensor-to-ECU Manchester-coded upstream messaging.

The PSI5-HOST architecture incorporates several safety-oriented features, including programmable watchdog timing slots monitoring, receive frame timestamps, and data protection using CRC or parity according to the PSI5 specification. These features allow smooth PSI5-HOST integration into ISO 26262-oriented automotive systems.

These features allow smooth PSI5-HOST integration into ISO 26262-oriented automotive systems.

Access to the PSI5-HOST registers is provided through an AMBA APB register interface. The silicon-proven PSI5-HOST core is designed to industry best practices and has been rigorously verified. Optional functional safety documents and dedicated diagnostic features help developers integrate the core into ISO 26262 safety-related automotive designs.
