The 24C02CTESN is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device offered by Microchip Technology. With a storage capacity of 256 x 8 bits, it is designed for applications requiring data storage that may need to be modified in use, including device configuration settings, calibration data, or small data logging tasks. Operating on a single supply voltage ranging from 1.7V to 5.5V, the 24C02CTESN supports the two-wire I2C serial interface, which allows for straightforward integration into a broad array of microcontroller-based systems. Its low power consumption and small package size (8-pin SOIC) make it particularly suited for portable and power-sensitive applications across consumer electronics, automotive, and industrial fields. This device also offers a write protect feature, ensuring data integrity by preventing unintended data overwrites. Its reliability, combined with Microchip's support for serial EEPROM devices, makes the 24C02CTESN a preferred choice for designers seeking stable and flexible data storage solutions.
