PSI5 Airbag System Reference Design Board

The Freescale Airbag Reference Platform (ARP) is an application demonstrator system which provides an airbag electronic control unit (ECU) implementation example using complete Freescale standard products for the growing automotive safety segment. The new ARP hardware is implemented using a standard Freescale Qorivva microcontroller (MPC560xP), analog and Xtrinsic Sensor family products. In the case of sensors, the families include both local ECU and PSI5 satellite sensors. The Airbag Reference Platform features a graphical user interface (GUI) firmware that allows customers to evaluate all Freescale chipset solution for airbag application. This ARP will reduce design risks and is easy and affordable to use, while representing the latest highest automotive quality standard.

Scalable system providing:

• Power supply for complete ECU
• Up to four satellite sensor interfaces (PSI5)
• Up to eight firing squibs
• Up to nine configurable switch input monitors for simple switch, resistive and Hall-effect sensor interface
• Safing block + watchdog

Verified combinations of parts delivering:

• Cost savings
• Scalability
• Reduced time to market
• SafeAssure Functional Safety Program

Friendly graphical user interface (GUI)
