24LC1025T-I/SM - EEPROM Memory IC | 1Mbit, I2C Interface, 400kHz | SOIC-8 Package

The 24LC1025T-I/SM from Microchip Technology Inc. is a high-capacity 1Mbit (128Kx8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for low-power and high-reliability data storage applications. Supporting the I2C serial interface, it operates across a broad voltage range of 2.5V to 5.5V and offers both byte and page write capabilities, with a 128-byte page write buffer for faster data throughput. With low power consumption, fast access times, and high endurance, this device is ideal for embedded systems, communications, industrial, and portable electronics requiring non-volatile memory with long-term data retention.
