Atmel’s MAC Serial EEPROMs for the IoT

As previously discussed on Bits & Pieces, the Internet of Things (IoT) refers to a future world where all types of electronic devices link to each other via the Internet. Today, it’s estimated that there are nearly 10 billion devices in the world connected to the Internet, a figure expected to triple to nearly 30 billion by 2020.

To be sure, the Internet of Things (IoT) is rapidly transforming products that have traditionally been categorized as stand-alone devices into smart products which are accessible via the Internet or capable of interacting with similar devices on a local network.

In order to successfully operate on the network, each device requires a unique identifying number which is commonly referred to as a MAC address. However, acquiring and maintaining a database of MAC addresses can be very cumbersome indeed. Fortunately, Atmel’s AT24MAC family provides a pre-programmed MAC address inside of a serial EEPROM device – without consuming any user memory area.

“By utilizing AT24MAC devices with globally unique hardware addresses embedded on-board, designers no longer need to absorb the management costs and time associated with acquiring, using and managing an allotment of MAC/EUI addresses,” an Atmel engineering rep told Bits & Pieces.

“The AT24MAC series makes it simpler, faster and less expensive to develop Internet-connected products. As it is based on Atmel’s proven and optimized serial EEPROM technology, the AT24MAC series of products provide the same high levels of endurance and data retention that engineers expect from us.”

It should also be noted that the AT24MAC series maintains byte-write capability and low power consumption. Meaning, engineers don’t have to sacrifice features or performance when adding  MAC address functionality to a design.

Additional key features include a unique pre-programmed MAC/EUI address, permanent and reversible EEPROM write protection, the ability to store and protect vital system data, an entire EEPROM array (available for use), unique serial numbers, pre-programmed true EUI-64 addresses and a pre-programmed, read-only 128-bit serial number.
