24LC512T-I/SM – EEPROM Memory IC | 512Kbit, I2C Interface, 400kHz | SOIC-8 Package
The 24LC512T-I/SM from Microchip Technology is a high-density 512Kbit (64Kx8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for reliable, low-power, and high-endurance non-volatile data storage. Featuring an I2C-compatible interface, this device supports both Standard (100kHz) and Fast (400kHz) communication modes, allowing for seamless integration with microcontrollers and embedded systems. With its wide voltage range (1.7V to 5.5V), 128-byte page write buffer, and hardware write-protect capability, the 24LC512T-I/SM is ideal for applications demanding data integrity and longevity in compact designs.
