8-DIGIT CALCULATOR
DESCRIPTION
The SC3423 is a single-chip LSI CMOS calculator with 8-digit four
function arithmetic operations, single memory, extraction of square
root and percentage calculation functions, leading zero and trailing
zero suppression, chain calculations and internal debouncing and
encoding of keyboard inputs. It is designed for LCD operation with
3.0V power supply (either from solar cell or battery), auto-power off,
low power dissipation and single power supply making the SC3423
ideal for hand held calculators with low system cost.
FEATURES
* Number of digits - 8 digits (rough estimated calculation is possible).
* Calculations:
- Standard four functions (+ , - , x , +).
- Chain multiplication and division.
- Auto-constant calculation (constant multiplicand, divisor,
addend and subtrahend).
- Square and reciprocal calculations.
- Extraction of square root.
- Percentage calculations.
- Power calculations.
- Rough estimate calculations.
- Memory calculations.
* Decimal point system-complete floating decimal point system.
* Negative number indication: number + minus (-) sign.
