描述 Description

The SPC574Sx is a family of next generation microcontrollers built on the Power

Architecture embedded category.

The SPC574Sx 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 140 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.
