TC83230-0022: Single-Chip CMOS LSI for Calculators with Printers
(applicable printer heads: M31T, M32T manufactured by EPSON)
The TC83230-0022 LSI is a single-chip CMOS LSI for use in
calculators with printers.
It integrates I/O logic circuits necessary to configure a
calculator with 10- and 12-digit display, two-memory function,
serial printer used to print calculation results, oscillator, and
LCD drivers.
Features
