A family of serial EEPROMs with built-in EUI-48- and EUI-64-compatible MAC addresses will be shown by Microchip Technology. The memories are designed to work on standard buses, such as SPI, I2C and UNI/O. They feature up to 1.5kbit of EEPROM that can be used for storing configuration and user settings, or as a scratch-pad area for buffering small amounts of data. The devices can be ordered when needed without volume restrictions. As they eliminate the need for designers to burn a unique MAC address into every microcontroller, they enable quick integration and shorter time-to-market at lower costs, says the company.The 24AA02E48, 25AA02E48 and 11AA02E48 serial-EEPROM devices have a built-in 48bit EUI (extended unique identifier) to identify the network hardware's physical address. The built-in MAC addresses enable designers to buy addresses only when needed and also eliminate the need for serialisation and programming. Appropriate EUI-48 networking applications include those involving Ethernet, 802.11, WiFi and Bluetooth. The devices are also suited for EUI-64 applications, such as those that use the FireWire, ZigBee/IEEE 802.15.4, Microchip's MiWi and IPv6 protocols. Visit Microchip, Hall X, Stand XX
