TC83230-0019

The TC83230-0019 is designed as single chip CMOS LSI for use in calculators with printers. TC83230-0019 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.

TC83230-0019 has seven features. (1)Print: 11 digits of data. 1 digit of minus sign, 1 digits of operational symbol. (2)Display: 10 digits of data (including punctuation in each digit). 1 digit of floating minus sign, memory I, II load, error symbol, grand total memory load, 3 digits of commas. (3)Decimal output: decimal set lock key controls output format. Fixed decimal setting, full floating point, and ADD/ADDII mode. (4)Key input buffer 12 words. (5)Operation methods: algebraic operation. (6)Function: four arithmatic functions, repeat multiplication and division, mixed calculation, square root calculation, percentage calculation, percent discourt and add-on calculations, memory calculation, add-mode calculation, mark up/down calculation, total calculation, constant calculation, tax calculation, two key rollover. (7)Leading zero suppression. That are all the main features.
