Microchip Technology introduced the 24AA025E48 cascadeable I2C serial EEPROM device. The EUI-64 compatible 24AA025E48 features pre-programmed EUI-48-node addresses. The EEPROM device enables designers to add MAC addresses to their designs on-the-fly. The address pins on the 24AA025E48 further enable designers to add more memory to their application, by allowing them to cascade up to eight EEPROM devices onto the I2C bus. The 24AA025E48 device is available in a 6-pin SOT-23 or 8-pin SOIC package, for $0.22 each in 10,000-unit quantities, for both package options.
