EM34014A 10/12-Digit Calculator
Battery/Solar/Dual Power Type
1 General Description
The EM34014A is a single-chip LSI CMOS calculator for 12-digit, 2-memory or 10-digit
2-memory devices. The EM34014A can drive the liquid crystal display (LCD) with a
single power supply. Single power supply operation, wide operating voltage and lower
power consumption make it suitable for 1.5V solar battery operated calculator.
Besides, the EM34014A can be selected to function in Auto Power-off or Manual
Power-off with Switch Key. It can also be selected with Memory Hold or Clear at
Power-off.
