A.HE83121 Introduction

HE83121 is a member of Jess Tech HE8000 series 8-bit CMOS micro-controller. This IC
provides 320 dots of LCD driver and 16-bit I/O pin. Besides, 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 128K ROM can store around 40 seconds of speech data. It is suitable for the application
in digital meter, stopwatch, thermometer and so on.

The HE83121 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.
