简 介:IZ1238M 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.
FUNCTIONS Four standard functions (+, -, × , ÷ ) The result of currency exchange operation is rounded to two decimal Auto constant calculations Mark-up and mark-down calculations Percentage calculations Chain multiplication and division Power calculations Rough estimate calculations Clear key: ON/C, CE Currency exchange calculations : Currency 1 → Currency 2 and Currency 2 → Currency 1
FEATURES Single chip CMOS construction Floating decimal point LCD direct drive Special memory for currency rates Overflow indication: “E” On-chip oscillator components Mirror type LCD Punctuation comma Auto Power off Saving special memory contents when auto power off Currencies C1, C2 indication Accumulating memory: M+, M-, MR, MC, MRC Bare chip is available
