The FM24C16 is a 16Kb serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Fairchild Semiconductor (now ON Semiconductor). It uses a 2-wire serial interface (I2C) for communication, making it easy to integrate into microcontroller-based systems. EEPROMs are used for non-volatile storage of data, meaning the data is retained even when power is removed.

Applications

• Storing Configuration Data
• Storing User Preferences
• Storing Calibration Data
• Data Logging
• Serial Presence Detect (SPD) in Memory Modules

Features
