Description

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 ofHE847701 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 of HE847701  is enough to most of battery operation system.
