A. HE80052S Introduction
HE80052S is a 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 156K ROM can store around 52 seconds of speech data (6KHz sampling rate
ADPCM). To simply the function of this IC, the functions removed are Slow Clock, Internal
Power-On Reset, Timer2, and Watch-dig Timer. Please note.
The HE80052S 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.
