KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE82005 HE80000 SERIES A. HE82005 Introduction HE82005 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. It is a power speech controller. 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). In order to simplify IC function, this IC have not exit follow list circuit, Slow Clock, Internal Power-ON Reset, Timer2 and Watch-dog Timer. Please pay attention. The TP automatic increase function still works in this IC. The instruction set of this IC 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.
