1 / 28 page TC83230-0015 2003-03-04 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC83230-0015 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. Features Operational Features · Print: 10 or 12 digits of data. (including decimal point.) 1 digit of floating minus sign, 1 digit of operational symbol. 1-color printing (black). · Display: 10 or 12 digits of data. (including punctuation in each digit.) 1 digit of floating minus sign, memory load, error symbol, grand total memory load, 3 digits of commas. · Decimal output: Decimal set lock key controls output format. Fixed decimal setting (“0”, “1”, “2”, “3”, “4”, “6”), full floating decimal, ADD mode and ADD2 mode. · Key-input buffer: 12 words · Operation methods: Addition and subtraction: By ARITHMETIC operation Multiplication and division: By algebraic operation · Function: Four function, repeat multiplication and division, mixed calculation, percentage calculation, percent discount and add-on calculation, memory calculation, delta percent calculation, add-mode calculation, mark-up/down calculation, total calculation, constant calculation, tax calculation Two-key rollover. · Leading zero suppression Protection (1) In the overflow condition, all key except “C”, “C/CE”, “CE”, “Feed”, “→” key are inoperative. (2) Key chatter protection. Auto-Clear at Power On Auto-clear functions by connecting a capacitor to the RESET pin. Weight: 1.52 g (typ.) |
