24LC02B/P

24LC02B/P Description

The 24LC02B/P from Microchip Technology is a 2Kbit (256 x 8) serial EEPROM designed for reliable non-volatile data storage in embedded systems. It operates over a wide voltage range (2.5V–5.5V) and supports I2C communication at up to 400 kHz, ensuring fast and efficient data transfers. With an access time of 900 ns and a write cycle time of 5ms (word/page), it balances speed with endurance. The device is housed in an 8-pin DIP package, making it suitable for through-hole mounting in prototyping or legacy systems. Its low-power EEPROM technology and industrial-grade temperature range (0°C to 70°C) make it ideal for diverse applications.
