NM24C08 - Fairchild

NM24C08 8K-Bit Standard 2-Wire Bus Interface Serial EEPROM

The NM24C08/09 devices are 8192 bits of CMOS non-volatile electrically erasable memory. These devices conform to all specifications in the Standard IIC 2-wire protocol and are designed to minimize device pin count, and simplify PC board layout requirements. The upper half (upper 4Kbit) of the memory of the NM24C09 can be write protected by connecting the WP .
