The M24C32-DFDW6TP is a 32 Kbit (4 kilobyte) Electrically Erasable Programmable Read-Only Memory (EEPROM) chip from STMicroelectronics that comes in a small 8-pin TSSOP package. This chip works at power supply voltages ranging from 2.5V to 5.5V and it has an I2C (Inter-Integrated Circuit) serial interface. This EEPROM is capable of performing a range of operations such as reading, writing, erasing, and verifying, and it is designed to be used in a variety of applications including data storage, parameterization and configuration of systems, and calibration. This EEPROM is also equipped with a security feature that allows it to be protected using a software data write protection and a hardware write protect pin.
