32-bit Power Architecture MCU for Automotive Chassis and Safety Applications

The 32-bit SPC570Sx automotive microcontrollers, (ASIL-D compliant) are a family of system-on-chip (SoC) devices designed to meet the challenges of the next generation of entry-level vehicle safety critical applications such as ABS and Airbag.

The SPC570Sx microcontrollers operate at speeds up to 80 MHz and offer high performance processing with low power consumption. They are compatible with the existing development infrastructure of current Power Architecture®devices and are supported with software drivers, operating systems and configuration code to assist with application development.
