1. General Description
HE84770 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 are 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 2 MB ROM 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 32 instructions with four
addressing modes are provided. Most of instructions take only 3 oscillator clocks to execute. The
processing power is enough to most of battery operation system.
2. Features
9 Operation Voltage: 2.4V ~ 3.6V
9 System Clock:
DC ~ 8MHz @ 3.6V
DC ~ 4MHz @ 2.4V
9 Internal ROM:
2 MB (256 KB Program ROM + 1792 KB Data ROM)
9 Internal RAM:
16 KB
9 Dual Clock System: Fast clock: 32768 ~ 8M Hz (No Internal Clock)
Slow clock: 32768 Hz
9 Operation Mode: Fast, Slow, Idle and Sleep modes.
9 24 ~ 48 bit bi-directional general purpose I/O port with push-pull or Open-Drain output type
selectable for each I/O pin by mask option. 24 of them are multiplexed with LCD segment
pins.
9 Built-in 4x20 hardware keyboard scan circuit (multiplexed with LCD SEG pin) helps to
reduce the pin counts as well as the firmware effort.
9 Voltage Detector with two detecting thresholds.
9 Four LCD configurations: 32 COM x 128 SEG, 48 COM x 112 SEG, 64 COM x 96 SEG or
80 COM x 80 SEG. All of LCD configurations are B TYPE.
9 Built-in LCD power supply with input voltage regulator, x3, x4, x5 voltage multiplier and
bias voltage generating circuit.
9 One 7-bit current-type DAC output.
9 Single-ended Pulse Width Modulation circuit for alternative voice output.
9 Built-in OP comparator.
9 Two 16-bit timers and one Time-Base timer.
9 Watch Dog Timer to prevent deadlock condition.
9 Two external interrupts and three internal timer interrupts.
9 Instruction set: 32 instructions with 4 addressing modes.
