Introduction
This document provides an overview of the SCF5249
ColdFire processor and general descriptions of
SCF5249 features and its various modules.
The SCF5249 was designed as a system
controller/decoder for MP3 music players, especially
portable MP3 CD players. The 32-bit ColdFire core with
Enhanced Multiply Accumulate (EMAC) unit provides
optimum performance and code density for the
combination of control code and signal processing
required for MP3 decode, file management, and system
control.
Low power features include a hardwired CD ROM
decoder, advanced 0.18um CMOS process technology,
1.8V core power supply, and on-chip 96KByte SRAM.
MP3 decode requires less than 20MHz CPU bandwidth
and runs in on-chip SRAM with external access only for
data input and output.
The SCF5249 is also an excellent general purpose
system controller with over 125 Dhrystone 2.1 MIPS @
140MHz performance at a very competitive price. The
