A.HE83R142 Introduction
HE83R142
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 + 16 Bit I/O Port...896 dots
LCD Driver + 24 Bit I/O Portetc. The built-in OP comparator can be used with (lightvoice
temperaturehumility) sensor and used as battery low detection. The 7-bit current-type D/A converter and
PWM device provide the complete speech output mechanism. The 256K ROM Size can be used in the
storage of speechgraphictext etc.. . It can be applicable to the medium systems such as Small-Scale
Dictionary, Data Bank, Educational Toy, Digital Voice Recording System etc. It also can be connected to
SRAM or Flash RAM for recording function.
The instruction set of HE83R142 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.
