T6A36S, JT6A36X-AS CMOS Single-Chip LSI for LCD Calculator
The T6A36S, JT6A36X-AS is a single-chip microcomputer for
8-digit 1-memory calculator.
T6A36S, JT6A36X-AS can drive the liquid crystal display
(LCD). Single power supply operation, low-power consumption
make it suitable for single battery operated pocketable calculator.
Features
· 8 digits of data and one symbol digit for calculator.
· Algebraic calculation mode.
· Punctuation.
· Standard 4 functions (+, −, ×, ÷), mark up percent with
automatic add-on/discount, automatic constant calculations,
chain calculations, memory calculations with memory overflow protection.
· Internal keyboard decoding and denouncing.
· Complementary output buffer for direct driving of liquid crystal display (LCD: FEM type −3.0 V, 1/2 bias, 1/3
duty).
· Single power supply (−1.5 V typ.).
· Quad in line flat package (60 pin).
· Very low-power consumption (3.0 µW typ. at wait).
· Very wide range of operating voltage (VSS = −1.2~−2.0 V).
· Automatic power off (A time for about 7 min).
