INTEGRAL IZ5851V

IZ5851V
CMOS 4-BIT SINGLE-CHIP APPLICATION-ORIENTED
MICROCOMPUTER WITH LCD DRIVER
( prototype LC5851N
SANYO).
DESCRIPTION
The IZ5851 is a CMOS 4-bit single chip microcomputer that operate on low voltage, very
low current and contain LCD drivers.
It also contain a 4 bit parallel processing ALU, a program memory ROM, data memory
(RAM),input & output port, Timer, many LCD segments outputs,
a prescaler, and a clock generator. A total of 79 instruction, including the operation and
processing instructions executable in 4 bits units, various conditional branch instructions
and LCD drivers data transfer instructions, from an easy- to-use and effective instruction
system.
