Introduction

Freescale Semiconductor

The MPC5643L family of 32-bit microcontrollers is the latest achievement in integrated automotive application controllers. It

belongs to an expanding range of automotive-focused products designed to address electrical hydraulic power steering (EHPS),

electric power steering (EPS) and airbag applications. The advanced and cost-efficient host processor core of the MPC5643L

automotive controller family complies with the Power Architecture embedded category. It operates at speeds as high as

120 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.
