4-Bit Microcomputer with Internal Driver
Overview
LC5812 series models 4-bit, single-chip, high-performance microcomputers equipped with drivers. They produced CMOS technology. Their numerous features include low-voltage operation current drain. parallel-processing ALU, program memory (ROM), data memory (RAM), input output ports, timer, clock generator, drivers, among other things, integrated single chip. instructions, including operation processing instructions executable 4-bit units various conditional branch instructions driver data transfer instructions form easy-to-use effective instruction system. HALT mode user readily implement clock function during low-power dissipation. minimize current required, overall internal operation stopped except oscillation frequency divider circuits drivers. HOLD mode operation system clock oscillation stopped that current drain becomes much less. LC5812 very useful controlling electronic tuners, cameras, other portable devices voltage, with power dissipation.
