TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC83230-0021,JTC83230-0021S

TC83230-0021, JTC83230-0021S: Single-Chip CMOS LSI for Calculators with Printers

(applicable printer heads: M-42V/42TV/41TAV/48T manufactured by EPSON)

The TC83230-0021, JTC83230-0021S 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-,12-, or 14-digit display, two-memory function,

serial printer used to print calculation results, oscillator, and

LCD drivers.

Features

Operational Features

Weight: 1.52 g (typ.)

Print: 14 digits (numerical value) + 1 digit (decimal point)

+ 2 digits (symbol) + 1 digit (minus) + 4 digits (commas)

Display: 10, 12 or 14 digits (numerical value) + 1 digit (sign)

with commas for separating thousand, million, billion and trillion units.

Decimal output: Floating point (F), specified decimal point (0, 1, 2, 3, 4, 5, 6), add mode (A)

Key-input buffer: 14 words

Operation methods: Addition and subtraction: By ARITHMETIC operation

Multiplication and division: By algebraic operation

Function: Four function, repeat multiplication and division, mixed calculation, square 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, rate conversion.

Two-key rollover

Leading zero suppression

Protection

(1) When an error occurs, only the following key inputs are valid: [C], [C/CE], [Feed], [OFF], [ON], [→],

and [P/NP].

(2) Key chatter protection (at f = 4 MHz)

At key read-in: 15 ms

At key off: 40 ms

Auto-Clear at Power On

Auto-clear functions by connecting a capacitor to the RESET pin.

Conditions for printing in red

(1) When keys except [−] and [M−] are pressed with print data which is signed negative.

(2) When the [−] or [M−] key is pressed with print data which is signed positive.

(3) When the intermediate operation result for MU/D or delta% is negative.
