V1.03
HE847701 is a member of 8-bit Micro-controller series developed by King Billion Electronics. Four LCD
driver configurations, 32 COM x 128 SEG, 48 COM x 112 SEG, 64 COM x 96 SEG or 80 COM x 80
SEG are available by mask option. 24 LCD segment driver pins multiplexed with I/O pins to provide
flexibility of wide variety of combinations to suit the needs of applications. The built-in LCD power
supply is equipped with voltage charge-pump circuit to generate the high voltage required by the high
duty LCD driver, bias voltage generating circuit and input voltage regulator circuit to supply stable LCD
display effect over the wide battery life. The built-in OP comparator can be used with (light, voice,
temperature, humility) sensor and used as battery low detection. 7-bit current-type D/A converter and
PWM device provide the complete speech output mechanism. The 2M ROM Size can be used in the
storage of speech, graphic, text, etc. It is ideal for applications such as Translator, Data Bank, Educational
Toy, Digital Voice Recording System, etc.
The instruction set of HE80000 series is 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 to execute.
The processing power is enough to most of battery operation system.
