KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE83715 HE80000 SERIES A. HE83715 Introduction HE83715 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users can chose any one of combination among 【128 dots LCD Driver + 16 Bit I/O Port】…【64 dots LCD Driver + 32 Bit I/O Port】etc. The built-in OP comparator can be used with (light、voice、 temperature、humility) sensor and used as battery low detection. And 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 (20 seconds at 3Kbytes per second), graphic, text etc. This IC is applicable to the small/medium systems such as Data Bank, Medium Class Educational Toy, Lower Second Voice Recording System etc.. The instruction set of HE83715 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.
