This specification is subject to change without notice. Please contact sales person for the latest version before use.

1. General Description

HE83003 is a member of 8-bit micro-controller series developed by King Billion. It’s 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 36K ROM size can be used in the storage of speech (20 seconds

at 3Kbytes per second)

The instruction set of HE83003 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.
