CMOS IC
LC5812
4-Bit Microcomputer
with Internal LCD Driver
Overview
The LC5812 series models are 4-bit, single-chip, high-per-
formance 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 inte-
grated on a single chip.
A set of 134 instructions, including the operation and pro-
cessing instructions executable in 4-bit units and various
conditional branch instructions and LCD driver data trans-
fer instructions form an easy-to-use and effective instruc-
tion 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 ex-
cept for the oscillation and frequency divider circuits and
the LCD drivers.
In HOLD mode the operation of the system clock oscilla-
tion is stopped so that the current drain becomes much less.
The LC5812 is very useful for controlling electronic tun-
ers, cameras, and other portable devices at low voltage, with
low power dissipation.
