General Description
The HT36F2 is an 8-bit high performance RISC archi-
tecture microcontroller specifically designed for various
music applications. It provides an 8-bit MCU and a
4-channel Wavetable synthesizer. It has a built-in 8-bit
microprocessor which controls the synthesizer to gen-
erate the melody by setting the special register. A HALT
feature is provided to reduce power consumption.
