SuperFlash® Memory with Embedded MAC Addresses

Let Us Manage the MAC Addresses for Your Cloud-Connected Products

Our family of Serial Quad I/O™ (SQI™) Flash devices with embedded MAC addresses are factory pre-programmed with uniquely global EUI-48™ and EUI-64™ addresses in a read-only, secure location without taking up any of the main memory space. From product development to production, our MAC address products ease the complexity of programming and serialization so you can get your Internet of Things (IoT) products to market faster.

Benefits of SuperFlash Memory with Embedded MAC Address

  • Factory programmed with uniquely global EUI-48 and EUI-64 addresses
  • Provides secure, easy, read-only access to the MAC address
  • Complements Microchip’s broad line of microcontrollers and networking products
  • Reduces manufacturing costs
  • Fast tracks products to market
  • Simplifies entry into the IoT market

Frequently Asked Questions

Are the MAC IDs in the MAC address Flash devices globally unique?

Yes, these pre-programmed MAC IDs from Microchip are globally unique. We only use Organizational Unique Identifiers (OUIs) set aside for Microchip by IEEE in these devices. IEEE uses OUIs to ensure different organizations use different MAC IDs that won't overlap. 

Are there any volume restrictions?

No, you can buy as many (or few) parts as you need, and these can be purchased as and when needed. Our minimum ordering quantity on tube versions of our devices is as low as one unit through our online store.

Can I tell the contents of the MAC address when I purchase a MAC address Flash device? Can I select the range of MAC IDs I need?

No, unfortunately we service several thousand customers directly and via distribution worldwide, and this will prove to be a very challenging logistical task to track which IDs reach which customers. As a result, the only way to tell the contents of the ID is by reading the actual device directly. Microchip will only ship MAC address Flash devices with Microchip OUIs.

I have my own MAC address that I need pre-programmed in memory. Can Microchip pre-program these for me?

No, Microchip is not authorized to sell other OUIs as a Microchip MAC address Flash device. However, if the volumes are big enough (1M+ units), we can certainly pre-program any data into our standard memory product and assign custom part numbers to them for your application. Please contact your local Microchip sales office to find out more about this service.

If I buy a reel of MAC Address devices, will the parts within a reel be serially programmed?
While we serially program these devices on wafer, they are often diced up, tested, packaged and stored in different patterns/combinations, which will disrupt their "serial-ness". As a result, we don't guarantee them to be serially arranged within a reel.

Are there smaller memory densities with embedded MAC address?

Please contact your local Microchip sales office or email us to inquire about custom options. We also offer a family of EEPROMs with MAC address.
