KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE83144 HE80000 SERIES A.HE83144 Introduction HE83144 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users can chose any one of combination among【1024 dots LCD Driver + 8Bit I/O Port】…【768 dots LCD Driver + 24 Bit I/O Port】etc. The 7-bit current-type D/A converter and PWM device provide the complete speech output mechanism. The 64K ROM Size can be used in the storage of speech、 graphic、text etc.. It can be applicable to the medium systems such as Small-Scale Dictionary, Data Bank, Pocket Dialer, Educational Toy etc. The instruction set of HE83144 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.HE83144 Feature z z Operation Voltage： System Clock： 2.2V – 5.5V DC ~ 8MHz @ 5.0V DC ~ 4MHz @ 2.2V 64K Bytes(64K Program ROM) 256 Bytes Normal (Fast) clock： 32.768K ~ 8MHz Slow clock： 32.768KHz DUAL、FAST、SLOW、IDLE、SLEEP Mode. z z z Internal ROM： Internal RAM： Dual Clock System ： z Operation Mode： z 8~24 bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin. 8 of them are shared with LCD segment pins. 1024~768 dots LCD driver (B TYPE selectable). One 7-bit current-type DAC output. PWM device. Two external interrupts and three internal timer interrupts. Two 16-bit timers and one Time-Base timer. Instruction set： 32 instructions, 4 addressing mode. 8-bit DATA POINTER for RAM and z z z z z z 16-bit TABLE POINTER for ROM. 1 V1.0E HE83144 KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 C.
