HE83750
HE80000 SERIES
A. HE83750 Introduction
HE83750 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users
can chose any one of combination among
銆?048

銆?792
dots LCD
鈥?/div>
Driver + 24 Bit I/O Port銆慹tc. The built-in OP comparator can be used with (light銆乿oice銆乼emperature銆?/div>
humility) sensor and used as battery low detection. And the 7-bit current-type D/A converter and PWM
device provide the complete speech output mechanism. The built-in DTMF generator can generate the
PSTN dialing tone directly. The 512K ROM Size can be used in the storage of large speech data,
graphic, text etc. It can be applicable to the medium systems such as Small-Scale Dictionary, Data Bank,
Pocket Dialer, Automatic Dialer Machine, Medium Level Educational Toy, Lower Second Voice
Recording System and connect external SRAM or Flash RAM for Higher Second Voice Recording etc..
The instruction set of HE83750 are quite easy to learn and simple to use. Only about thirty instructions
with four-type addressing mode are provided. Most of instructions take only 3 oscillator clocks (machine
cycles). The processing power is enough to most of battery operation system.
