HT36B0 --
8-Bit Music Synthesizer MCU
General Description
The HT36B0 is an 8-bit high performance RISC-like microcontroller specifically designed for music applications.
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 HT36B0 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.
