24LC64T-E/SN - EEPROM Memory IC | 64Kbit, I2C Interface, 400kHz | SOIC-8 Package

The 24LC64T-E/SN from Microchip Technology is a highly reliable 64Kbit (8Kx8-bit) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) that uses a 2-wire I2C-compatible interface. It is engineered for low-power, high-endurance applications, offering both Standard (100kHz) and Fast (400kHz) communication modes. With its wide operating voltage range, hardware write protection, and robust data retention, this device is well-suited for industrial, consumer, and communication systems that demand secure, long-term non-volatile memory storage.
