A.HE83750 Introduction

HE83750 is a member of Jess Tech HE8000 series 8-bit CMOS micro-controller. This IC can
share the LCD pin and I/O pin (From 2048-dot of LCD driver + 16 Bit I/O Port ... 1792-dot of
LCD driver + 24 Bit I/O Port), the combination of the above is selected by Mask Option. It built-
in one internal Op-Amp, one 7-bit D/A converter, one DTMF generator and one PWM output
module to provide a speech output interface. Use the built-in 512K ROM can store around 160
seconds of speech data.
The HE83750 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.
