HT37Q70/HT37Q60/HT37Q50/HT37Q40/HT37Q30/HT37Q20
-- 4-Channel Music Synthesizer MCU General Description
The device is an 8-bit high performance RISC
architecture microcontroller specifically designed for various Music
and ADPCM applications. It provides an 8-bit MCU and 4-channel
Wavetable synthesizer. It has a integrated 8-bit micro controller
which controls the synthesizer to generate the melody by setting the
special register. A Power-down function is included to reduce power
consumption.
