A.HE83144 Introduction
HE83144
is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd
.
Users can chose any one of combination among 1024 dots LCD Driver + 8Bit I/O Port...768 dots
LCD Driver + 24 Bit I/O Portetc. The 7-bit current-type D/A converter and PWM device provide the
complete speech output mechanism. The 64K ROM Size can be used in the storage of speech
graphictext etc.. It can be applicable to the medium systems such as Small-Scale Dictionary, Data
Bank, Pocket Dialer, Educational Toy etc.
The instruction set of HE83144 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.
