HE80128M
HE80000 SERIES
A. HE80128M Introduction
HE80128M is a member of Jess Tech HE8000 series 8-bit CMOS micro-controller. This chip is a
Power Speech Controller. It built-in one internal Op-Amp, one 7-bit D/A converter and one
PWM output module to provide a speech output interface. Use the built-in 384K ROM can store
around 128 seconds of speech data (8KHz sampling rate ADPCM). Use external SRAM or Flash
RAM for recording function.
The HE80128M provides a very simple and effective instruction set, each instruction byte
occupies only 1.5 clock cycle time, therefore, it is suitable to apply in the high performance
systems.
