General Description

The device is an 8-bit high performance RISC architec-

ture microcontroller specifically designed for various

Music and ADPCM applications. It provides an 8-bit

MCU and 4-channel Wavetable synthesizer. It has a in-

tegrated 8-bit micro controller which controls the syn-

thesizer to generate the melody by setting the special

power consumption.
