Description: 128K-bit/ 256K-bit SPI SERIAL ELECTRICALLY ERASABLE PROM<<<>>>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
