Introduction
This document provides an overview of the MCF5251
ColdFire processor and general descriptions of the
MCF5251 features and modules. Also provided are
electrical specifications, pin assignments, and package
diagrams for MCF5251 ColdFire
Processor. For
functional characteristics, refer to the
MCF5251
Reference Manua
l (MCF5251RM).
The MCF5251 is a system controller/decoder for
compressed audio music players addressing both
portable and automotive solutions supporting CD, HDD
and USB based systems. The 32-bit ColdFire core with
enhanced multiply and accumulate (eMAC) unit
provides optimum performance and code density for the
combination of control code and signal processing
required for compressed audio decode, file management,
and system control.
Low power features include flexible PLL (with
power-down mode) with dynamic clock switching, a
hardwired CD ROM decoder, advanced 0.13 μm CMOS
process technology, 1.2 V core power supply, and
on-chip 128K-byte SRAM.
