8-DIGITS CURENCY CALCULATOR

The IZ1238M 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 IZ1238M has special keys (C1, C2, SM) for

currency exchange calculations and special memory for save currency rate. The result of

currency exchange operations rounded to two decimal if it exceeds two decimal.
