Datasheet Summary
Powered by GS/AI

The Microchip 24AA64/24LC64/24FC64 is a 64 Kbit Serial EEPROM with a 2-wire I²C interface, designed for low-power applications. It operates with a supply voltage range of 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz. The device features a single block memory organization of 8K x 8 bits and includes a 32-byte page write buffer, allowing efficient data writing. Active current consumption is up to 3 mA, while standby current is as low as 1 µA. The EEPROM is rated for over 1 million erase/write cycles and offers data retention exceeding 200 years. It is available in various package types, including TSSOP-8, and is compliant with RoHS standards. The device also includes hardware write protection and ESD protection greater than 4,000V, making it suitable for industrial and automotive applications.
