The MPC5646C is a new family of next generation microcontrollers built on the Power Architecture embedded category. This document describes the features of the family and options available within the family members, and highlights important electrical and physical characteristics of the device. 

The MPC5646C family expands the range of the MPC560xB microcontroller family. It provides the scalability needed to implement platform approaches and delivers the performance required by increasingly sophisticated software architectures. The advanced and cost-efficient host processor core of the MPC5646C automotive controller family complies with the Power Architecture embedded category, which is 100 percent user-mode compatible with the original Power Architecture user instruction set architecture (UISA). It operates at speeds of up to 120 MHz and offers high performance processing optimized for low power consumption. It also 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
