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.
