KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE84772 HE80000 SERIES A. Introduction HE84772 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. User can chose any one of combination among 32COM： 【4096 dots LCD Driver + 24 Bit I/O Port】…【3328 dots LCD Driver + 48 Bit I/O Port】or 48COM： 【5376 dots LCD Driver + 24 Bit I/O Port】…【4224 dots LCD Driver + 48 Bit I/O Port】or 64COM： 【6144 dots LCD Driver + 24 Bit I/O Port】…【4608 dots LCD Driver + 48 Bit I/O Port】or 80COM：【6400 dots LCD Driver + 24 Bit I/O Port】…【4480 dots LCD Driver + 48 Bit I/O Port】. Users can choose one of LCD configuration through “Mask Option”. With built-in regulator circuit, LCD display will be stable. 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 512K ROM Size can be used in the storage of speech、graphic、text etc.. It can be used in Translator、Data Bank、Pocket Dialer、 Educational Toy、Digital Voice Recording System etc The instruction set of HE8XXXX 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. B.

With WDT (WATCH DOG TIMER) to prevent deadlock condition. 24~48 bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin. 24 of them are shared with LCD segment pins. The new built-in hardware auto scan keyboard (4*20) (shared with LCD SEG Pin) not only reduces the hardware cost, but also reduces the firmware effort. One built-in OP comparator. One Voltage Detector with two detecting threshold Vth. (Vth=2.4V/2.4v). Users can select any one of four LCD configuration---32COM*128SEG LCD , 48COM*112SEG LCD , 64COM*96SEG LCD or 80COM*80SEG LCD. All of LCD configuration are B TYPE(please refer to HE80000 user’s manual, section 4.3.9 LCD control register)。It is built-in type-III regulator, the LCD can display stably. The highest LCD voltage LVP must small than 8.5 Volt. LCDC[7:0]=[－－－G GGBE]。G : gray level control、B :blank(1)、E: enable(1)。 Normally, The LCD refresh rate is around 64 Hz. But for this IC, 32 COM configuration ~= 170 Hz and 48 COM configuration ~= 110 Hz One 7-bit current-type DAC output. PWM device. (No Rate Selection, connect with VDD & PWMP) 1 V2.43E HE84772 KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE80000 SERIES z Two external interrupts and three internal timer interrupts. z Two 16-bit timers and one Time-Base timer. z Instruction set： 32 instructions, 4 addressing mode. 14-bit DATA POINTER for RAM and 19-bit TABLE POINTER for ROM.
