A. HE847701 Introduction
HE847701 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd, User
can configure 32COM【4096 dot LCD driver + 24 Bit I/O Port】…【3328 dot LCD driver + 48 Bit I/O
Port】LCD driver,or 48COM:【5376 dot LCD driver + 24 Bit I/O Port】…【4224 dot LCD driver + 48
Bit I/O Port】
,or 64COM:【6144 dot LCD driver + 24 Bit I/O Port】…【4608 dot LCD driver + 48 Bit I/O
Port】
,or 80COM:【6400 dot LCD driver + 24 Bit I/O Port】…【4480 dot LCD driver + 48 Bit I/O Port】
The configuration of LCD driver was selected from mask option。Built-in power regulator circuit,make
the LCD display more stable。The built-in OP comparator can be used with (light, voice, temperature,
humility) sensor or battery low detection. A 7-bit current type D/A converter and PWM device provide the
complete speech output mechanism.。The 2M byte ROM and 16K byte RAM can be used as the storage
of large speech data, graphic, text etc. It can be used for Dictionary, Data Bank, Medium Level
Educational Toy, Low duration Voice Recording System etc..
The instruction set are quite easy to learn and simple to use. There are only about thirty instructions
with four-type addressing modes are provided. Most of instructions take only 3 oscillator clocks (machine
cycles), which is the high efficiency and low power MCU.

zNew RC type oscillator,accuracy at ±5%,maximum frequency up to around 10 MHz。Please refer
to the detail frequency table on section F。
zWith WDT (WATCH DOG TIMER) to prevent deadlock condition.。
z24~48 bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output
mode for each I/O pin.
zThe new built-in hardware auto scan keyboard(4*20)(shared with LCD SEG pin),not only reduce the
hardware cost, but also reduce the firmware effort。
zBuilt-in OP comparator。
zUser can select any one of three LCD configurations --- 32COM*128 SEG LCD,48COM*112 SEG
LCD, 64 COM*96 SEG, or 80 COM*80 SEG LCD。The LCD scan signal are Type B(please refer
to HE80000 user’s manual, section 4.3.9 LCD control register), It is built-in type-IV LCD driver.
The highest LCD voltage LVP must be lower than 8.5Volt。
zProvide LFR and LDL output signal,which can be connected to KDS80,as a LCD Segment
extension。
zLCDC[7:0]=[---G GGBE]。G : gray level control、B :blank(1)、E: enable(1)。
zThe 847701 provide different refresh cycle for different display configuration: 32 COM : Refresh
Cycle=~170Hz,48 COM : Refresh Cycle=~110Hz ,64 COM : Refresh Cycle=~64Hz,80 COM :

Refresh Cycle=~64Hz。
zOne 7-bit current type D/A 。The new DAC output structure,which do not need to use capacitor to
adjust the input current of 8050C。Provide Mask Option to select different output current
3mA=>4Ω, 1.5mA=>8Ω, 0.75mA=>16Ω, 0.375mA=>16Ω,to make sure there will be no signal
saturation。
zPWM device。(No Rate Selection, connect with VDD & PWMP) 。Dedicated GND pin for PWM
block。
zTwo external interrupts and three internal timer interrupts。
zTwo 16-bit timers and one Time-Base timer。
zInstruction set: 32 instructions, 4 addressing modes. 14-bit DATA POINTER for RAM and 21-bit
TABLE POINTER for ROM。
