SCF5249

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 ROMdecoder, 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. Theintegrated peripherals and EMAC allow the SCF5249 to replace both the microcontroller and the DSP in certain applications. Most peripheral pins can also be remapped as General Purpose I/O pins.
