The MCF5271 family is a highly integrated
implementation of the ColdFire^® family of reduced
1
instruction set computing (RISC) microprocessors. This ²
document describes pertinent features and functions of
3
4
the MCF5271 family. The MCF5271 family includes the ⁵
MCF5271 and MCF5270 microprocessors. The
6
7
differences between these parts are summarized below in 8
Table 1. This document is written from the perspective of ⁹
the MCF5271 and unless otherwise noted, the
information applies also to the MCF5270.

The MCF5271 family combines low cost with high
integration on the popular version 2 ColdFire core with
over 144 (Dhrystone 2.1) MIPS at 150 MHz. Positioned
for applications requiring a cost-sensitive 32-bit
solution, the MCF5271 family features a 10/100 Ethernet
MAC and optional hardware encryption to ensure the
application can be connected and protected. In addition,
the MCF5271 family features an enhanced multiply
accumulate unit (eMAC), large on-chip memory (64
Kbytes SRAM, 8 Kbytes configurable cache), and a
32-bit SDR SDRAM memory controller.
