TC83230-0015: Single-Chip CMOS LSI for Calculators with Printers
(applicable printer heads: M31/M31A manufactured by EPSON)
The TC83230-0015 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- or 12-digit display, two-memory function,
two-tax function, serial printer used to print calculation results,
oscillator, and LCD drivers.
