IZ1228/IZ1228M

8-DIGIT CALCULATOR

The IZ1228/IZ1228M are a single chip CMOS LSI with 8-digit arithmetic operation, single memory,

extraction-of-square-root,

percentage calculation and auto power off function, designed for FEM LCD operation with a 1.5V

power supply. The IZ1228M has

special keys (C1, C2, SM) for currency exchange calculations and special memory for save

currency rate.
