FM24C128 – 128K-Bit Standard 2-Wire Bus Interface Serial EEPROM FM24C128 – 128K-Bit Standard 2-Wire Bus Interface Serial EEPROM December 2001 General Description FM24C128 is a 128Kbit CMOS non-volatile serial EEPROM organized as 16K 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). FM24C128 is designed to minimize pin count and simplify PC board layout requirements. FM24C128 offers hardware write protection where by the entire memory array can be write protected by connecting WP pin to VCC. The entire memory then becomes unalterable until the WP pin is switched to VSS. “LZ” and “L” versions of FM24C128 offer very low standby current making them suitable for low power applications. This device is offered in SO, TS...
