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 HE83003provide 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.
