MCF5251 ColdFire® Microprocessor Data Sheet

Introduction
This document provides an overview of the MCF5251 ColdFire processor and general descriptions of the MCF5251 features and modules. Also provided are electrical specifications, pin assignments, and package diagrams for MCF5251 ColdFire® processor. For functional characteristics, refer to the MCF5251 Reference Manual (MCF5251RM).

The MCF5251 is a system controller/decoder for compressed audio music players addressing both portable and automotive solutions supporting CD, HDD and USB based systems. The 32-bit ColdFire core with enhanced multiply and accumulate (eMAC) unit provides optimum performance and code density for the combination of control code and signal processing required for compressed audio decode, file management, and system control.

The MCF5251 is a general purpose system controller with over 125 Dhrystone 2.1 MIPS @ 140 MHz performance. The integrated peripherals and EMAC allow the MCF5251 to replace both the microcontroller and the DSP in certain applications. Most peripheral pins can also be remapped as general purpose I/O pins.
