HE83131

      HE83131 is a member of 8-bit Micro-controller series that is developed by King Billion.This IC built-in 640-dot LCD driver and has one OP comparator.The built-in OP comparator can be used with light\vioce\temperature\humility sensor etc.The 7-bit current-type D/A converter and PWM device provide the complete speech output mechanism.This IC is applicable to the medium systems such as LCD Games and Educational Toy etc.Use external SRAM or Flash RAM to have recording function.HE83131 is very easy to learn and use.Most of instructions take only 3 oscillator clocks.As a result this IC is suitable for the applications that higher performance system.
