AT24C128N-10SU-2.7 128Kbit I²C Serial EEPROM – SOIC-8 – Microchip

The AT24C128N-10SU-2.7 from Microchip (formerly Atmel) is a high-reliability 128 Kbit (16K × 8) serial EEPROM designed for non-volatile data storage in embedded systems. Using a 2-wire I²C-compatible serial interface, this device offers easy integration into microcontroller-based applications requiring secure and persistent data retention.

Operating from a 2.7V to 5.5V supply range, the AT24C128N supports clock speeds up to 1 MHz, making it suitable for both low-power and high-performance designs. It features a fast 550 ns access time, internal write cycle management, and self-timed write capability for simplified system design.

Packaged in a compact 8-pin SOIC, this EEPROM provides long endurance, excellent data retention, and reliable performance across a wide –40°C to +85°C industrial temperature range. Typical applications include configuration storage, calibration data, identification records, logging systems, industrial controllers, and consumer electronics.
