Description

HE83R125 is a member of 8-bit MCU series developed by King Billion. 32 LCD segment driver pins are multiplexed ith /O pins to provide flexibility of wide variety of combinations to suit the needs of applications Users can choose any one of combinations from 320 dots LCD Driver with 8 Bit I/O Port to 64 dots LCD Driver with 40-bit I/O Port, etc. by mask ption. The HE83R125 built-in LCD power regulator can provide stable LCD display effect over wide range of battery voltage. The Pulse th Modulation with complementary outputs provides the complete speech output mechanism. The 128K ROM can store und 40 second of speech. This chip is applicable to the small/medium systems such as LCD Games, Perpetual ar . instruction set or HE80000 easy to learn and use. Most of instructions take
