AT24C128, 128-Kbit Serial EEPROM, SOIC-8

The AT24C128 is a 128-Kbit serial EEPROM designed for high-reliability, low-power applications requiring non-volatile data storage. It utilizes an I2C (2-wire) interface for efficient communication with microcontrollers and embedded systems.

Organized as 16,384 x 8-bit, this EEPROM provides ample space for firmware, configuration data, and system settings. Its wide operating voltage range (1.8V - 5.5V) ensures compatibility with a variety of applications, including industrial automation, automotive electronics, and consumer devices.

For data protection, the AT24C128 features a write-protect pin (WP) and programmable block protection, ensuring secure and controlled data modification. The EEPROM supports self-timed write cycles (5ms typical) and high endurance of 100,000 write/erase cycles with 40-year data retention.

Encased in a compact SOIC-8 package, this EEPROM is ideal for automotive, industrial, consumer electronics, and embedded applications where secure and reliable memory storage is required.
