The MCF5275 family is a highly integrated

implementation of the ColdFire? family of reduced

instruction set computing (RISC) microprocessors. This

document describes pertinent features and functions

characteristics of the MCF5275 family. The MCF5275

family includes the MCF5275, MCF5275L, MCF5274

and MCF5274L microprocessors. The differences

between these parts are summarized in Table 1. This

document is written from the perspective of the

MCF5275 and unless otherwise noted, the information

applies also to the MCF5275L, MCF5274 and

MCF5274L.

The MCF5275 family delivers a new level of

performance and integration on the popular version 2

ColdFire core with up to 159 (Dhrystone 2.1) MIPS @

166MHz. These highly integrated microprocessors build

upon the widely used peripheral mix on the popular

MCF5272 ColdFire microprocessor (10/100 Mbps

Ethernet MAC and USB device) by adding a second

10/100 Mbps Ethernet MAC (MCF5274 and MCF5275)

and hardware encryption (MCF5275L and MCF5275).
