MCF5253 ColdFire? Microprocessor Data Sheet

Introduction

This document provides an overview of the MCF5253 ColdFire processor and general descriptions of the MCF5253 features and modules. Also provided are electrical specifications, pin assignments, and package diagrams for MCF5253 ColdFire? processor. For functional characteristics, refer to the MCF5253 Reference Manual (MCF5253RM).

The MCF5253 is a general purpose system controller with over 125 Dhrystone 2.1 MIPS @ 140 MHz performance. The integrated peripherals and EMAC allow the MCF5253 to replace both the microcontroller and the DSP in certain applications. Most peripheral pins can also be remapped as general purpose I/O pins.

Low power features include flexible PLL (with power-down mode) with dynamic clock switching, a hardwired CD ROM decoder, advanced 0.13 μm CMOS process technology, 1.2 V core power supply, and on-chip 128K-byte SRAM.
