SC3449 Datasheet, PDF (1/22 Pages) Silan Microelectronics Joint-stock – PROGRAMMABLE CALCULATOR WITH 10BIT

SC3449
PROGRAMMABLE CALCULATOR WITH 10-BIT DUAL DISPLAY
DESCRIPTION
The SC3449 is a monolithic CMOS circuit for scientific calculators,
having the basic calculation, the memory calculation, fraction calculation,
percentage calculation, scientific function calculation, statistics back to
return to compute, degree, cent, second calculation etc. ,and you can
directly press the key according to the sequence of the formulas, while
the calculators will automatically operate in terms of the algorithm. Using
a 3V power supply it can display ten arithmetic figures, 12 characters
composing of lattice, and the state mark of the calculation. The
calculator can turn off by itself.
