HE83116B is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. This HE83116B IC build-in 128-dot LCD driver, and also have 16-bit I/O port. 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), graphic, text etc. This IC is applicable to the small systems such as calculating machine, perpetual calendar, digital watch etc.. The instruction set of HE83116B 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.
