DESCRIPTION

The IS25C128 and IS25C256 are electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications. The IS25C128 is 128Kbit (16K x 8) and the IS25C256 is 256Kbit (32K x 8). The IS25C128/256 EEPROMs are offered in a wide operating voltage range of 1.8V to 5.5V for compatibility with most application voltages. ISSI designed the IS25C128/256 to be an efficient SPI EEPROM solution. The devices are packaged in 8-pin JEDEC SOIC, 8-pin EIAJ SOIC, and 8-pin PDIP.
