HE80000 SERIES
A. HE83005 Introduction
HE83005 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd It is
.
、
、
、
a power speech controller. The built-in OP comparator can be used with (light voice temperature
humility) 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).
The instruction set of HE83005 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.
