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.
