Cascadeable EUI-48 I2C serial EEPROM device from Microchip

Microchip has made available the 24AA025E48, a cascadeable I2C serial EEPROM device with pre-programmed EUI-48-node addresses. This device expands Microchip's existing family of EUI-48 devices in I2C, SPI, and UNI/O buses. It is EUI-64 compatible and enables designers to add MAC addresses to their designs on-the-fly. This device can cascade up to eight EEPROM devices onto the I2C bus thus enabling designers to add more memory to their application. These capabilities can be added on without changing the existing I2C serial EEPROM device and without having to pay for and register a block of code with the IEEE.

The 24AA025E48 addresses the need for providing a large amount of memory for buffering data for Networking and wireless applications. It also meets the need of providing MAC addresses, to therefore provide a physical address that is identifiable on the network. Each device ships with unique, write-protected code.

"As networking and wireless applications continue to grow over the next several years, the demand for MAC addresses is expected to follow," said Randy Drwinga, vice president of Microchip's Memory Products Division. "The 24AA025E48 device from Microchip provides quick and easy access to MAC addresses, at low costs. Its address pins enable users to quickly add an EUI-48 node address to an existing application, without replacing their current I2C EEPROM device."

Package: 6-pin SOT-23, 8-pin SOIC

Price: 24AA025E48 is priced at US$0.22 for 10,000-unit quantities
