HE85750
HE80000 SERIES
A. HE85750 Introduction
HE83761 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users
can chose 32 COM for any one of combination among
銆?048
dots LCD Driver + 12 Bit I/O Port銆戔€?/div>
銆?280
dots LCD Driver + 36 Bit I/O Port銆慹tc.. or 48COM for any one of combination among
銆?304
dots LCD Driver + 12 Bit I/O Port銆戔€︺€?152 dots LCD Driver + 36 Bit I/O Port銆慹tc.. The built-in OP
comparator can be used with (light voice temperature 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 256KB ROM and 2KB RAM 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,
Medium Level Educational Toy, Lower Second Voice Recording System etc..
The instruction set of HE85750 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.
