Atmel CS and MAC Series Serial EEPROMs
Value Added Serial EEPROMs with Pre-Programmed
128-bit Serial Numbers and MAC Addresses
AT24MAC Series Serial EEPROM
The Internet of Things is rapidly turning products that traditionally have been
stand-alone devices into smart products that are accessible via the Internet or can
interact with other similar devices on a local network. In order to successfully operate
on the network, each device needs a unique identifying number which is commonly
referred to as a MAC address.
Acquiring and maintaining a database of MAC addresses, however, can be very
cumbersome. The Atmel AT24MAC family alleviates this burden by providing
a pre-programmed MAC address inside of a Serial EEPROM device, without
consuming any user memory area. By utilizing the new AT24MAC devices with
globally unique hardware addresses embedded onboard, designers no longer need
to absorb the management costs and time associated with acquiring, using and
managing an allotment of MAC/EUI addresses. The AT24MAC series makes it simpler,
faster and less expensive to develop Internet-connected products.
By being based upon Atmel’s proven and robust Serial EEPROM technology, the
AT24MAC series of products provide the same high levels of endurance and data
retention that customers have come to expect from Atmel. The products also maintain
byte-write capability and low power consumption so that customers need not sacrifice
features and performance when choosing to add the MAC address functionality to
their design.
Application Examples for CS and MAC Series Serial EEPROMs
