MICROCHIP 24AA025E48T-I/OT EEPROM 2Kbit EUI-48 I2C SOT-23

The MICROCHIP 24AA025E48T-I/OT is a 2Kbit I²C™ Electrically Erasable Programmable Read-only Memory (EEPROM) that comes pre-programmed with a globally unique EUI-48 node address. This makes it an ideal solution for applications that require a unique identifier for network or node identification without the need for external programming.

This memory device is organised as two blocks of 128 x 8-bit memory and communicates via a 2-wire serial interface (I²C compatible), supporting clock frequencies of 100kHz and 400kHz. The low-voltage design allows operation down to 1.7V, with maximum standby and active currents of only 1µA and 1mA respectively, ensuring energy-efficient performance.

The EEPROM offers a 16-byte page write buffer and a self-timed erase/write cycle, with a typical page write time of just 3ms. It also features low-power CMOS technology, Schmitt-trigger inputs for noise suppression, and output slope control to eliminate ground bounce. With more than 1 million erase/write cycles and over 200 years of data retention, this device delivers reliable, long-term data storage.

Important Notices: This product is an ESD-sensitive device; proper precautions must be observed during handling. Market demand has extended lead times, and delivery dates may vary. This product is exempt from discounts.
