DESCRIPTION

The IS25C02 and IS25C04 are electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications. The IS25C02 is 2Kbit (256x 8) and the IS25C04 is 4Kbit (512x 8). The IS25C02/04 EEPROMs are offered in a wide operating voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed the IS25C02/ 04 to be an efficient SPI EEPROM solution. The devices are packaged in 8-pin PDIP, 8-pin SOIC, and 8- pin TSSOP.
