HE85750
HE80000 SERIES
A. HE85750 Introduction
1
V1.51E
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
1280 dots LCD Driver + 36 Bit I/O Port
etc.. or 48COM for any one of combination among
dots LCD Driver + 12 Bit I/O Port
…
1152 dots LCD Driver + 36 Bit I/O Port
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..
2048 dots LCD Driver + 12 Bit I/O Port
…
2304
etc.. The built-in OP
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.
