IN5732
4BIT SINGLE CHIP MICROCOMPUTER
The IN5732 is a CMOS 4-bit single chip microcomputer that operate on low voltage,
very low current and contain LCD drivers. They also contain a 4 bit parallel processing
ALU, a program memory ROM, many LCD segment outputs, a prescaler, an oscillator.
The IN5732 is especially suited for use in high-grade timepieces, time controllers,
electronic calculators, LCD games with timepiece. The IN5732 is especially suited for use
in audio equipment, copiers, facsimiles with LCD and sub CPU applications.
