SPC570S40E1CEFAY STMicroelectronics 32bit MCU

SPC570S40E1CEFAY Overview

The SPC570Sx is a family of next generation microcontrollers built on the Power Architecture embedded category.

The SPC570Sx family of 32-bit microcontrollers is the latest achievement in integrated automotive application controllers. It belongs to an expanding family of automotive-focused products designed to address the next wave of Chassis and Safety electronics applications within the vehicle. The advanced and cost-efficient host processor core of this automotive controller family complies with the Power Architecture embedded category and only implements the VLE (variable-length encoding) APU, providing improved code density. It operates at speeds of up to 80 MHz and offers high performance processing optimized for low power consumption. It capitalizes on the available development infrastructure of current Power Architecture devices and is supported with software drivers, operating systems and configuration code to assist with users implementations.
