A.HE83540 Introduction

HE83540 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 1024-dot of LCD driver + 16 Bit I/O Port ... 896-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. In addition, it can be connected with external SRAM or Flash RAM for
recording function.
The HE83540 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.

External Slow Clock pin .
Connecting with 32768Hz
crystal or resistor as slow

source for LCD display,
TIMER1, Time-Base and
other internal block.

Mask Option settings :
