HE83139
HE80000 SERIES
A. HE83139 Introduction
HE83139 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. This
IC provides 512 pixels LCD display and built-in OP comparator can be used with light, voice,
temperature and humility sensor or used to detect the battery low. The 7-bit current-type D/A converter
and PWM drive output provide the complete speech output mechanism.
The 64K bytes ROM size can be used to store 15 seconds speech data. It can be applicable to the LCD
game, medium level educational toy, lower second voice recording system or used with external
command mode SRAM or Flash RAM for higher second voice recording 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.
