FM24C08U/09U – 8K-Bit Standard 2-Wire Bus Interface Serial EEPROM August 2000 FM24C08U/09U – 8K-Bit Standard 2-Wire Bus Interface Serial EEPROM General Description The FM24C08U/09U devices are 8192 bits of CMOS non-volatile electrically erasable memory. These devices conform to all specifications in the Standard IIC 2-wire protocol. They are designed to minimize device pin count and simplify PC board layout requirements. The upper half (upper 4Kbit) of the memory of the FM24C09U can be write protected by connecting the WP pin to VCC. This section of memory then becomes unalterable unless WP is switched to VSS. This communications protocol uses CLOCK (SCL) and DATA I/O (SDA) lines to synchronously clock data between the master (for example a microprocessor) and the slave EEPROM device(s). The Standard IIC protocol allows for a maximum of 16K of EEPROM memory which is supported by the Fairchild family in 2K, 4K, 8K, and 16K devices, allowing the user to configure the memory as the ...
