Equipped with EUI-48(TM) and EUI-64(TM) compatible MAC addresses, Models 24AA02E48, 25AA02E48, and 11AA02E48 provide up to 1.5 Kb of EEPROM and work on standard busses, such as SPI, I2C(TM), and UNI/O® bus. MAC addresses are write-protected and eliminate need for serialization and programming. Featuring built-in 48-bit Extended Unique Identifier to identify hardware's physical address, EEPROMs are suited for applications involving Ethernet, 802.11 WiFi(TM), Bluetooth®, FireWire, and ZigBee®/IEEE 802.15.4(TM).
Microchip Technology Introduces Serial EEPROMs with Built-in MAC Addresses
EUI-48(TM) and EUI-64(TM)Compatible Devices Provide Easy, Inexpensive Access to MAC Addresses on Most Standard Buses with Serial EEPROM Functionality
CHANDLER, Ariz., Dec. 9, 2008 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today introduced a family of serial EEPROM devices with built-in EUI-48(TM) and EUI-64(TM) compatible MAC addresses. Designed to work on standard busses, such as SPI, I2C(TM) and the UNI/O® bus, the devices provide easy and inexpensive access to MAC addresses, and feature up to 1.5 Kb 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 and, because they eliminate the need for designers to burn a unique MAC address into every microcontroller (MCU), they enable quick integration and shorter time-to-market at lower costs.
The 24AA02E48, 25AA02E48 and 11AA02E48 serial EEPROM devices have a built-in 48-bit Extended Unique Identifier (EUI) that is needed to identify the network hardware's physical address. These built-in MAC addresses enable designers to buy addresses only when needed, and also eliminate the need for serialization and programming. The address is also EUI-64 compatible, and it is write-protected to ensure tamper-proof designs. Being compatible with standard, well-known busses, these serial EEPROMs can easily be incorporated into existing designs. Additionally, they offer EEPROM features such as high endurance, large operating-voltage and temperature ranges, and low operating and standby currents; enabling robust serial-interface designs with low power draw.
"The networking industry is demanding easily accessible, plug-and-play MAC address memory devices," said Randy Drwinga, vice president of Microchip's Memory Products Division.
"Microchip's new MAC-address chips meet this need by providing low-cost, easy access to MAC addresses, along with serial EEPROM functionality. The devices demonstrate our continued commitment to satisfying customer needs with innovative products that help reduce costs and shorten time to market."
Example EUI-48 networking applications for which the new EEPROMs are appropriate include those involving Ethernet, and 802.11 WiFi(TM) and Bluetooth® technology, among others. The devices are also well-suited for EUI-64 applications, such as those that utilize the FireWire, ZigBee®/IEEE 802.15.4(TM), Microchip's MiWi(TM) and IPv6 protocols. Specific examples include applications in the consumer (home appliances, Internet radios, wireless LANs, DVRs, LCD TVs) and industrial markets (remote sensing, HVAC, Ethernet, metering).
