Description

The SCF5249VF140 is one member of the SCF5249 family which 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. Also it is a general purpose system controller with over 125 Dhrystone 2.1 MIPS @ 140MHz performance at a very competitive price.

Features of the SCF5249VF140 are:(1)analog/digital converter;(2)ide and smartmedia interfaces;(3)queued serial peripheral interface (QSPI) (master only) two timers;(4)two UARTS;(5)CD-ROM and CD-ROM XA block decoding and encoding function;(6)digital audio transmitter and two receivers compliant with IEC958 audio protocol;(7)serial audio interface which supports IIS and EIAJ audio protocols;(8)supports 16-bit wide SDRAM memories;(9)operates from external crystal oscillator;(10)96-KByte SRAM (A 64K and a 32K bank);(11)integrated enhanced multiply-accumulate unit (EMAC);(12)8-kbyte direct mapped instruction cache.

The absolute maximum ratings of the SCF5249VF140 can be summarized as:(1)supply core voltage:-0.5 to +2.5 V;(2)maximum core operating voltage:+1.98 V;(3)minimum core operating voltage:+1.62 V;(4)supply I/O voltage:-0.5 to +4.6 V;(5)maximum I/O operating voltage:+3.6 V;(6)minimum I/O operating voltage:+3.0 V;(7)input voltage:-0.5 to +6.0 V;(8)storage temperature range:-65 to150 .If you want to know more information such as the electrical characteristics about the SCF5249VF140, please download the datasheet in www.seekic.com or www.chinaicmart.com .
