A.HE83760 Introduction

HE83760 is a member of Jess Tech HE80000 series 8-bit CMOS micro-controller. This IC has
3072-dot of LCD driver + 32 Bit I/O Port. It built-in OP comparator can be used with (light
voicetemperaturehumility) senor and used as battery low detection. The 7-bit current-type D/A
converter and PWM can be used in the storage of speechgraphictext etc.. The built-in DTMF
generator can generate the PSTN dialing tone directly.
HE83760 can be used in TranslatorData Bank Pocket DialerEducational ToyDigital voice
Recording System etc.
The instruction set of HE83760 are quite easy to learn and simple to use. Only about thirty
instructions with four-type addressing mode are provided. Most of instructions take 3 oscillator
clocks (machine cycles). The processing power is enough to most of battery operation system.

External Slow Clock pin .
Connecting with
32768Hz crystal or resistor
as slow clock and
providing clock source for
LCD display. TIMER1,
Time-Base and other
internal blocks.

Mask Option settings :
MO_FCK/SCKN=00Slow Clock only

01Illegal
10Dual Clock
11Fast Clock only

MO_FOSCE=0Internal fast oscillation

MO_FXTAL=0R,C oscillation for Fast Clock

1Crystal oscillation for Fast Clock

MO_SXTAL=0R,C oscillation for 32.768K Clock

1X'tal oscillation for 32.768K Clock

Use OP1and OP2 to switch among different operation
mode (NORMAL, SLOW, IDEL and SLEEP). In Dual
Clock mode, the main system clock is still the Fast
Clock. The 32768Hz clock is for LCD and timer1 only.
