TC83230-0024: Single-Chip CMOS LSI for Calculator with Printers
(printer heads: PTMFL 63 by ALPS)
The TC83230-0024 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-digit display, two memory functions and TWO
TAX functions, serial printer used to print calculation results,
oscillator, and LCD drivers.
