11 MAC Address Chips Need easy, low-cost access to MAC addresses? Will access to plug-and-play MAC address chips enable faster time to market? Dec 2008 EUI-48 Programmed Serial EEPROMs 2 Kb Serial EEPROMs 1/2 array WP - Hardware 24AA02E48 25AA02E48 11AA02E48 1.8V 5.5V 400KHz ¼ Array WP - Software ¼ Array WP - Software 1.8V 5.5V 1.8V 5.5V 10MHz 100KHz Pre-Programmed 48-bit MAC Address Chips EUI-48 & EUI-64 Compatible 1.5 Kb Serial EEPROM Functionailty SPI, I 2 C and UNI/O Bus Write-Protected Codes SOIC and SOT-23 I 2 C SPI UNI/O 12

12 and what does it solve? EUI-48 codes are sold by IEEE Volume based Step1: Buy Code EUI-48 Codes Solution 2Kbit Standard EEPROM EUI-48 Plug-and-Play! Option1 Option 2 $1,600 to buy 16.7M codes Cost of Serialization & $550 to buy 4096 codes Programming Issue: EUI-48 is difficult to obtain, expensive, time consuming Most MCU s don t come with built-in EUI-48 Address. Microchip s MAC Address Chips We do all the above! ~$0.25 each!! Available in SPI, I 2 C and UNI/O Bus Scratch Pad EEPROM Write- Protected Step2: Program MCU Low Cost Easy to access Faster time to market EUI-64 Compatible Serial EEPROM Functionailty No Hassles, Easy Access No Volume Restrictions!! 13
