General Description

The HT36B2 is an 8-bit high performance RISC archi-

tecture microcontroller specifically designed for various

music applications. It provides an 8-bit MCU and a 16

channel wavetable synthesizer. The program ROM

which can be easily programmed is composed of both

program control codes and wavetable voice codes.

The HT36B2 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 fea-

ture is provided to reduce power consumption.
