HE83149
HE80000 SERIES
A. HE83149 Introduction
HE83149 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd.
Users can choose any one of combination among
銆?024
dots LCD Driver + 8 Bit I/O Port銆戔€︺€?68
dots LCD Driver + 24 Bit I/O Port銆慹tc. The 7-bit current-type D/A converter and PWM device
provide the complete speech output mechanism. The 256K bytes ROM size can be used in the storage
of speech銆乬raphic銆乼ext etc.. It can be applicable to the medium systems such as Small-Scale
Dictionary, Data Bank, Pocket Dialer, and Educational Toy etc.
The instruction sets of HE80000 series 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 performance of HE83750S is enough for most of battery operation
system.
