TC83220-0019 2003-02-12 1 toshiba cmos digital integrated circuit silicon monolithic TC83220-0019 TC83220-0019: single-chip cmos lsi for fl (fluorescent) calculator with printers the toshiba printing/display calculator circuit TC83220-0019 is 10- or 12-digit calculator on single-chip cmos lsi. TC83220-0019 can drive the printing machine (ptmfl-76/77, ptmfl-86/87; alps) with magnet driver circuit, and can drive the fluorescent display tube with dc-dc converter. it contains a 4 k-word rom, a 256 4-bit ram. features operational features print: 11 or 13 digits of data. (including decimal point) 1 digit of minus sign. 2 digits of operational symbol. 3 digits of commas. 1-color (black) or 2-colors (black and red) printing. 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, and add mode. key input buffer: 12 stages function: 4 basic arithmetic functions (+, ? , , ). repeat addition and subtraction. automatic constants in multiplication, division, percent calculation, calculations. automatic percent add-on and percent discount calculation. memory calculation. automatic accumulating calculation. gross margin profit calculation. delta percent calculation. tax calculation. grand total calculation. item counter: 0~999 count up or ? 999~0~999 count up/down by depressing of + , ? key. punctuation: commas for thousands on display. kinds of touch key: weight: 4.12 g (typ.) www..net

(1) setting power sw to on, v 2 is supplied to v dd pin, and also to hold pin. then calculator operates normally. (2) setting power sw from on to off, v 1 is supplied to v dd pin and v ss is supplied to hold pin. under this connection, tax rate is held. (3) setting power sw to on, v 2 is supplied to v dd pin, and also to hold pin. then calculator operates normally with tax rate to be held. note 12: v 1 (battery) should be supplied to the circuit after v 2 (dc) supply, because of prevention from exhaustion of battery and abnormal operation. www..net
