HT36F2 is an 8-bit high performance RISC architecture 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 generate the melody by setting the special register. A HALT feature is provided to reduce power consumption.
This technical document describes the HT36F2 8‑bit microcontroller designed for music synthesizer applications. It includes an overview of the architecture, block diagram, and key features such as a built‑in 32K×16‑bit ROM, 208×8‑bit RAM, 16 bidirectional I/O lines, two programmable timers, and a mono 16‑bit DAC.
The datasheet also provides detailed pin assignments, electrical characteristics, memory organization, instruction set details, and information on the interrupt system. Additional mechanical data such as carrier tape dimensions for the SOP packages are listed at the end of the document.
