DESCRIPTION
The IS25C08B is an 8Kbit (1024x 8) electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications.
This EEPROM operates in a wide voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed this device to be a practical, low-power SPI EEPROM solution. The devices are offered in lead-free, RoHS, halogen free or Green. The available package types are 8-pin SOIC, TSSOP, UDFN and CSP.
