Overview

The LC5812 series models are 4-bit, single-chip, high-performance microcomputers equipped with LCD drivers. They are produced by CMOS technology. Their numerous features include low-voltage operation and low current drain.

A 4 bit parallel-processing ALU, program memory (ROM), data memory (RAM), input and output ports, a timer, a clock generator, and LCD drivers, among other things, are integrated on a single chip.

A set of 134 instructions, including the operation and processing instructions executable in 4-bit units and various conditional branch instructions and LCD driver data transfer instructions form an easy-to-use and effective instruction system.

In HALT mode the user can readily implement the clock function during low-power dissipation. To minimize the current required, overall internal operation is stopped except for the oscillation and frequency divider circuits and the LCD drivers.

Application Examples

• Portable equipment (camera control, various card controls, high-quality electric calculators and timers).

• Acoustic equipment (electronic control, electronic tuning, and clocks).

• Household electrical apparatus (remote control, and timer control).

• Telephone equipment (telephone control, and display control).
