HE83131
HE80000 SERIES
A.HE83131 Introduction
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銆乿oice銆乼emperature銆乭umility) 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.
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.
