MCF5271 Integrated Microprocessor Hardware Specification
The MCF5271 family is a highly integrated implementation of the
ColdFire® family of reduced 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 1. This document is written
from the perspective of 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.
