A.HE83115 Introduction
HE83115
is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd
.
Users can chose any one of combination among 80 dots LCD Driver + 12 Bit I/O Port...48 dots
LCD Driver + 20 Bit I/O Portetc. The built-in OP comparator can be used with (lightvoice
temperaturehumility) sensor and used as battery low detection. And 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 (20 seconds at 3Kbytes per second), graphic, text etc. This IC is
applicable to the small systems such as sport match, sport recorder, digital watch etc..
The instruction set of HE83115 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.
