Introduction
Document overview
This document provides electrical specifications, pin assignments, and package diagrams for the MPC5642A series of
microcontroller units (MCUs). It also describes the device features and highlights important electrical and physical
characteristics. For functional characteristics, refer to the device reference manual.
1.2
Description
This microcontroller is a 32-bit system-on-chip (SoC) device intended for use in mid-range engine control and automotive
transmission control applications.
It is compatible with devices in Freescale’s MPC5600 family and offers performance and capabilities beyond the MPC5632M
devices.
The microcontroller’s e200z4 host processor core is built on the Power Architecture
®
technology and designed specifically for
embedded applications. In addition to the Power Architecture technology, this core supports instructions for digital signal
processing (DSP).
The device has two levels of memory hierarchy consisting of 8 KB of instruction cache, backed by a 128 KB on-chip SRAM
and a 2 MB internal flash memory.
For development, the device includes a calibration bus that is accessible only when using the Freescale VertiCal Calibration
System.
