ROMless Coldfire V2 32-Bit Microcontroller MCF524x Series 1.8V 144-LQFP
SCF5249LAG120 Description
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.
SCF5249LAG120 Features
DMA controller with 4 DMA channels
Integrated Enhanced Multiply-accumulate Unit (EMAC)
8-KByte Direct Mapped Instruction Cache
96-KByte SRAM (A 64K and a 32K bank)
Operates from an external crystal oscillator
Supports 16-bit wide SDRAM memories
Serial Audio Interface which supports IIS and EIAJ audio protocols
Digital audio transmitter and two receivers compliant with IEC958 audio protocol
CD-ROM and CD-ROM XA block decoding and encoding function
Two UARTS
Queued Serial Peripheral Interface (QSPI) (Master Only)
Two timers
IDE and SmartMedia interfaces
Analog/Digital Converter
Flash Memory Card Interface
Two I2C modules
System debug support
General Purpose I/O pins shared with other functions
