C December 2001 © 2001 Fairchild Semiconductor Corporation FM24C64 – 64K-Bit Standard 2-Wire Bus Interface Serial EEPROM General Description FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM orga- nized as 8K x 8 bit memory. This device confirms to Extended IIC 2-wire protocol that allows accessing of memory in excess of 16Kbit on an IIC bus. This serial communication protocol uses a Clock signal (SCL) and a Data signal (SDA) to synchronously clock data between a master (e.g. a microcontroller) and a slave (EEPROM). FM24C64 is designed to minimize pin count and simplify PC board layout requirements. FM24C64 offers hardware write protection where by the entire memory array can be write protected by connecting WP pin to VCC. This section of memory then becomes unalterable until the WP pin is switched to V SS. “LZ” and “L” versions of FM24C64 offer very low standby current making them suitable for low power applications. This device is offered in SO, TSSOP and DIP packages. Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consump- tion.
