24LC02B-E/ST Description

The 24LC02B-E/ST from Microchip Technology is a 2Kbit (256 x 8) I2C-compatible serial EEPROM designed for low-power, high-reliability data storage 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 systems requiring efficient read/write operations. The device is housed in an 8-pin TSSOP package, optimized for surface-mount assembly, and complies with ROHS3 and REACH environmental standards. Its 5ms write cycle time (word/page) ensures robust performance in data-intensive applications.
