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.
