MCF5251

ColdFire Processor

Freescale Semiconductor 

Introduction

MP3 decode requires less than 20 MHz CPU bandwidth and runs from on-chip SRAM.

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.
