MCU and system basis chip combo ease design of safety-critical features With two new SafeAssure solutions – the Qorivva MPC574xP 32-bit microcontroller (MCU) and system basis chip (SBC) MC33906/7/8 families –Freescale help automotive systems meet all Automotive Safety Integrity Levels (ASIL) up to and including the most stringent one, ASIL D. Applications that can benefit include electric power steering, electronic stability control, vehicle dynamic and chassis control, safety domain control, adaptive cruise control and blind spot detection.

The Qorivva MPC574xP MCU and MC33906/7/8 SBC families are designed from the ground up in a way that system manufacturers can more easily achieve system compliance with functional safety standards by providing:

Integrated safety architectures in hardware

Accompanying safety software

A comprehensive support infrastructure that helps reduce development time.

The Freescale SafeAssure program includes an extensive selection of MCUs, sensors and analog ICs, as well as support including training, safety documentation and technical support for functional safety application design. The system-level approach helps developers reduce the complexity of achieving compliance with safety standards while building advanced safety performance into their systems, explained Reza Kazerounian, senior vice president and general manager of Freescale's Automotive, Industrial & Multi-Market Solutions Group. For this reason, the chip vendor has included its latest Qorivva MCU and the new generation of SBCs in the company's SafeAssure program.

This program is designed to help system manufacturers more easily achieve system compliance with functional safety standards: International Standards Organization (ISO) 26262 and International Electrotechnical Commission (IEC) 61508. The program highlights Freescale solutions hardware and software that are optimally designed to support functional safety implementations and come with a rich set of enablement collateral.

As consumer awareness and legal requirements drive enhancements in automotive safety, automotive OEMs face increased complexity at the electronic control unit (ECU) level. Using the MPC574xP MCU in conjunction with Freescale SBC devices helps simplify system design and optimize interactions at the monitoring and diagnostic and software architecture levels, while each device has its own fail-safe check mechanism.
