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 synchro nously 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.
