The 24LC02BT-E/SN is a 2K bit Serial Electrically Erasable Programmable Read Only Memory (EEPROM) integrated circuit manufactured by Microchip Technology. This device is suitable for applications that require non-volatile memory such as data logging, remote device configuration, or product identification and authentication. The device uses an 8-pin package and communicates to a variety of microcontrollers via the 2-wire serial bus. The 24LC02BT incorporates a 512-byte page write memory buffer which allows up to 8 bytes of data to be written at a time. The device can be write-protected using the hardware write protect pin, and the data is protected during power loss thanks to the internal low voltage detection circuit. The device has a wide temperature range, making it suitable for applications in various environments.
