KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE83750S HE80000 SERIES A. HE83750S Introduction HE83750S is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users can choose any one of combination among 【2048 dots LCD Driver + 16 Bit I/O Port】…【1792 dots LCD Driver + 24 Bit I/O Port】etc. which is determined by mask options. The built-in OP comparator can be used with light, voice, temperature and humility sensor or used to detect the battery low. The 7-bit current-type D/A converter and PWM drive output provide the complete speech output mechanism. The built-in DTMF generator can generate the PSTN dialing tone directly. The 512K bytes ROM size can be used in the storage of large speech data, image and text etc. It can be applicable to the medium systems such as small-scale dictionary, data bank, pocket dialer, automatic dialer machine, medium level educational toy, lower second voice recording system or used with external command mode SRAM or Flash RAM for higher second voice recording etc. The instruction sets of HE80000 series 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 performance of HE83750S is enough for most of battery operation system. B.
