MICROCHIP 24AA02E48T 2Kbit I2C EEPROM with EUI-48 Node Identity, SOT-23-5

The MICROCHIP 24AA02E48T-I/OT is a highly integrated 2Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) featuring a preprogrammed, globally unique 48-bit EUI-48 node identity. This compact component is housed in a space-saving 5-pin SOT-23 surface-mount package, making it an ideal solution for modern, dense electronic designs where board real estate is at a premium.

Organised as two blocks of 128 x 8-bit memory, the device utilises a two-wire I2C serial interface for communication. Its advanced low-voltage design allows for reliable operation from 1.7V to 5.5V, ensuring compatibility with a wide range of logic families and battery-powered applications. This flexibility is complemented by exceptional power efficiency, with a maximum standby current of just 1μA and a maximum active current of 1mA.

Key Features & Performance

• Page Write Capability: Supports writing of up to 8 bytes of data in a single operation, with a typical page write time of 3ms, streamlining data storage routines.
• High-Speed Interface: Operates at a maximum clock frequency of 400kHz, enabling fast data transfer.
• Robust Design: Built with low-power CMOS technology and includes Schmitt trigger inputs for superior noise suppression and output slope control to eliminate ground bounce, ensuring signal integrity in electrically noisy environments.
• Proven Endurance & Retention: Offers a remarkable endurance of more than 1 million erase/write cycles and data retention greater than 200 years, guaranteeing long-term reliability.
• Unique Identifier: Comes preprogrammed with a factory-set, unique 48-bit node address (EUI-48), eliminating the need for manual configuration and providing a ready-made hardware identity for networked devices.
• Wide Temperature Range: Fully operational across an industrial temperature range of -40°C to +85°C, suitable for demanding applications.<br /
