TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

T6F19,JT6F19-AS

T6F19, JT6F19-AS CMOS Single-Chip LSI for LCD Calculator

The T6F19, JT6F19-AS is a CMOS single-chip microcomputer

for 12-digit capacity 1-memory calculation.

T6F19, JT6F19-AS is the complete single chip CMOS LSI for

calculator with single power supply operation.

Wide operating voltage range and low power consumption

make it suitable for 1.5 V solar battery operated.

Besides T6F19, JT6F19-AS can selectable with a

pin-programmable to function of Power timer and Memory hold.

With the following features.

Features

Weight: 1.52 g (typ.)

•

Display: 12 digits (selectable with a pin-programmable) of

data, 2 digits of sign, error symbol, memory load symbol.

•

Algebraic mode.

Standard 4 functions (+, −, ×, ÷)

Rate conversion calculation

Automatic percentage operation with add-on, discount.

Automatic delta percentage, mark-up and markdown operations.

Square root.

Constant calculation.

Chain calculation.

Change sign.

Floating point or momentary mode (selectable with a switch).

Fixed point (“0”, “1”, “2”, “3”, “4” or “6” places) or floating point (selectable with a switch).

Adding point mode (selectable with a switch).

Rounding switches (rounding up, down and off).

Leading zero suppression.

Trailing zero suppression.

Punctuation on display, commas for thousands.

Memory contents indicator, turned on with non-zero in the memory.

Registration overflow, indicating that too many digits are entered (the most significant digit are protected).

Result overflow, indicating during calculation (most function key are locked as it happened).

Memory overflow indicating to flashing of memory load mark.

Key roll over function.

Floating minus.
