HE82015
HE80000 SERIES
A. HE82015 Introduction
HE82015 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd
.
It is
a power speech controller. The 7-bit current-type D/A converter and PWM device provide the complete
speech output mechanism. The 128K ROM Size can be used in the storage of speech (40 seconds at
3Kbytes per second). In order to simplify IC function, this IC have not exit follow list circuit,
Slow
Clock, Internal Power-ON Reset, TP automatic increase, Timer2 and Watch-dog Timer.
Please pay
attention.
The instruction set of HE82015 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.
