SiP(System in Package) LSI of;
Single-Chip Digital Servo Processor incorporating CD Head Amplifier/Compression
AudioDecoder and 16Mbit DRAM for ESP(Electrical Shock Proof) function.

The TC94A93MFG is a single chip processor which incorporates the following functions: CD Head amplifier, EFM synchronous signal separation protection
and interpolation, EFM demodulation, error correction, microcontroller interface, servo-use digital equalizer and servo control circuit, multi bit DA converter and Compression audio decoder firmware such as for MP3, WMA , MPEG4-AAC and 16Mbit
DRAM for ESP. The TC94A93MFG makes it possible to configure a CD-MP3 player with ESP quite easily with an adjustment-free basis.
