24LC02B-I/ST

24LC02B-I/ST Description

The 24LC02B-I/ST from Microchip Technology is a 2Kbit (256 x 8) serial EEPROM with an I2C interface, designed for reliable non-volatile data storage in low-power applications. Operating within a 2.5V to 5.5V supply range, it supports a 400 kHz clock frequency and features a fast 900 ns access time, making it suitable for high-performance embedded systems. The device is housed in an 8-pin TSSOP package, optimized for surface-mount applications where space efficiency is critical. With a 5ms write cycle time for word or page operations, it ensures efficient data updates while maintaining endurance and retention characteristics typical of EEPROM technology.
