A. HE83751 Introduction
HE83751 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. User
can choose any one of combination among 2048 dots LCD Driver + 16 Bit I/O Port...1792 dots LCD
Driver + 24 Bit I/O Port etc. The 64K ROM Sizes can be used in the storage of speech data, graphic,
text, etc.
The instruction set of HE83751 is quite easy to be learned and simple to use. Only about thirty
instructions with four-type addressing modes are provided. Most of instructions take only 3 oscillator
clocks (machine cycles). The power consumption is very low and suitable for battery operation system.
