General Description
The HT36M4 is an 8-bit high performance RISC
microcontroller specifically designed for music applica-
tions. 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, which can easily be programmed.
The HT36M4 has a built-in 8-bit microprocessor with
64K´16 program ROM, 384´8 data RAM, 12
bidirectional I/O, encapsulated in 20 TSSOP for applica-
tions where need tinny package such as ring tone gen-
erator for CELLULAR/DECT/CORDLESS PHONES.
