IS25C256 Description
The IS25C128 and IS25C256 are electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for munications. The IS25C128/256 EEPROMs are offered in a wide operating voltage range of 1.8V to 5.5V for patibility with most application voltages. ISSI designed the IS25C128/256 to be an efficient SPI EEPROM solution.
