AT24C02

The AT24C02 is a 2-kilobit (256 x 8 bits) serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Atmel (now part of Microchip Technology). It utilizes the I2C (Inter-Integrated Circuit) communication protocol, allowing multiple devices to be connected on the same bus with only two wires (SDA for data and SCL for clock).
The AT24C02 features a wide operating voltage range of 1.8V to 5.5V, making it suitable for various applications. It supports byte-wise and page-wise (up to 8 bytes) writing, with a standard write time of about 5 milliseconds. The device has a 1 million write/erase cycle endurance and can retain data for up to 100 years under proper conditions.
Common applications include calibration data storage, configuration settings, and small data storage in systems like microcontrollers, industrial equipment, and consumer electronics. The compact design and efficient power consumption make AT24C02 an ideal choice for low-power applications.
