It provides an 8-bit MCU and a 16 channel wavetable synthesizer.
The program ROM is composed of both program control codes and wavetable voice codes, and can be easily programmed.
The HT36A0 has a built-in 8-bit microprocessor which programs the synthesizer to generate the melody by setting the special register from 20H~2AH.
A HALT feature is provided to reduce power consumption.
