HT37A70/HT37A60/HT37A50/HT37A40/HT37A30/HT37A20
-- 8-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 8-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.
