Hardware Specification

32-bit Embedded Controller Division

The MCF5271 family is a highly integrated

implementation of the ColdFire

instruction set computing (RISC) microprocessors. This

document describes pertinent features and functions of

the MCF5271 family. The MCF5271 family includes the

MCF5271 and MCF5270 microprocessors. The

differences between these parts are summarized below in

Table

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 96 (Dhrystone 2.1) MIPS at 100MHz. 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.
