Description

The microcontroller’s e200z4 host processor core is built on 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 MPC5644A has two levels of memory hierarchy consisting of 8 KB of instruction cache, backed by 192 KB on-chip SRAM and 4 MB of internal flash memory. The MPC5644A includes an external bus interface, and also a calibration bus that is only accessible when using the Freescale VertiCal Calibration System.

This document describes the features of the MPC5644A and highlights important electrical and physical characteristics of the device.
