The MCF5251 is a system controller/decoder for

compressed audio music players addressing both

portable and automotive solutions supporting CD, HDD

and USB based systems. The 32-bit ColdFire core with

enhanced multiply and accumulate (eMAC) unit

provides optimum performance and code density for the

combination of control code and signal processing

required for compressed audio decode, file management,

and system control.
