Overview
The Microchip AT24C02-10PC is a 2Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It communicates with the host controller using an I²C (2-wire) serial bus interface. This EEPROM is designed for storing non-volatile memory data and is optimized for use in various industrial and commercial applications where low-power and low-voltage operation are essential. The device can retain data for at least 100 years with more than 1 million erase and write cycles, making it highly reliable for long-term data storage.
