      Introduction
      This document provides an overview of the SCF5250
      ColdFire processor and general descriptions of
      SCF5250 features and its various modules.
      The SCF5250 was designed as a system
      controller/decoder for compressed audio music players,
      especially portable and automotive CD and hard disk
      drive 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 audio
      decoding and post processing, file management, and
      system control.
      Low power features include a hardwired CD ROM
      decoder, advanced 0.13um CMOS process technology,
      1.2V core power supply, and on-chip 128KByte SRAM
      that enables Windows Media Audio (WMA) decoding
      without the need for external DRAM in CD applications.
      The SCF5250 is also an excellent general purpose
      system controller with over 110 Dhrystone 2.1 MIPS @
      120MHz performance at a very competitive price. The
      SCF5250
