KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE83122 HE80000 SERIES A. HE83122 Introduction HE83122 is a member of 8-bit Micro-controller series that is developed by King Billion. This IC built-in 320-dot LCD driver and has one OP comparator. The built-in OP comparator can be used with (light、voice、temperature、humility) sensor etc. The 7-bit current-type D/A converter and PWM device provide the complete speech output mechanism. The 64K ROM Size can storage around 20 second’s speech. This IC is applicable to the small/medium systems such as LCD Games and Perpetual Calendar etc. This IC is very easy to learn and use. Most of instructions take only 3 oscillator clocks (machine cycles). As a result this IC is suitable for the applications that require higher performance system.
