HE80170S
HE80000 SERIES
A. HE80170S Introduction
HE80170S 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 512K ROM can store around 170 seconds of speech data (8KHz sampling rate ADPCM). Use external SRAM or Flash RAM for recording function. The HE80170S provides a very simple and effective instruction set, each instruction byte occupies only 1.
