A. HE80032S Introduction
HE80032S is a member of Jess Tech HE80000 series 8-bit CMOS micro-controller. This chip is a
Power Speech Controller. It built-in one 7-bit D/A converter and one PWM output module to
provide a speech output interfaces. Use the built-in 96K ROM can store around 32 seconds of
speech data (6KHz sampling rate ADPCM). To simply the function of this IC, the functions
removed are Slow Clock, Timer2, and Watch-dig Timer. Please note.
The HE80032S provides a very simple and effective instruction set, each instruction byte
occupies only 1.5 clock cycle time, therefore, and it is suitable to apply in the high performance
systems.
