The 24C02C-E/P is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) IC manufactured by Microchip. It offers a wide range of features, including 2K bits of EEPROM (256 bytes), low-power CMOS technology, defined and tested endurance and data retention periods, fast bus-mastering for quick and efficient access, a low-voltage design that supports operation with 1.8V and 5V voltage levels, an advanced write protection mechanism, and more. The device also supports both I2C and SPI protocols for communication with the microcontroller.
