DESCRIPTION

The IS25C08 and IS25C16 are electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications. The IS25C08 is 8Kbit (1024x 8) and the IS25C16 is 16Kbit (2048 x 8). The IS25C08/16 EEPROMs are offered in a wide operating voltage range of 1.8V to 5.5V compatible with most application voltages. ISSI designed the IS25C08/16 to be an efficient SPI EEPROM solution. The devices are packaged in 8-pin PDIP, 8-pin SOIC, 8-pin TSSOP, and 8-ball CSP.
