1. General Description
HE83R123 is a member of 8-bit MCU series developed by King Billion. 32 LCD segment driver pins are
multiplexed with I/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 option. The built-in LCD power regulator can
provide stable LCD display effect over wide range of battery voltage. The Pulse Width Modulation with
complementary outputs provides the complete speech output mechanism. The 64K ROM can store around
20 second of speech. This chip is applicable to the small/medium systems such as LCD Games, Perpetual
Calendar etc. The instruction set or HE80000 easy to learn and use. Most of instructions take only 3
oscillator clocks. This chip is suitable for the applications that require higher performance.

4. LCD Power Supply
The LCD power supply is equipped with input power regulator, voltage charge pumt, and bias voltage
generating resistor network. The input power of MCU is regulated and multiplied by 4 times to generate
LCD bias for LCD driver. The regulator output voltage can be adjusted by the resistor between LV1 and
LVF pads.
