AT24CS Series Serial EEPROM
Almost every application in production today can benefit from or already requires a
unique identifier or serial number. This number allows identification and tracking for
multiple purposes including node identity, build control, version control, customer
tracking and authenticity check. Building and maintaining an infrastructure to assign
and maintain the serialization of products, particularly in high-volume production
lines across multiple locations, can be challenging.
The Atmel® AT24CS series of devices helps resolve this problem by including
a unique, factory-programmed, read-only 128-bit Serial Number that can help
customers simplify inventory control of mass production lines and enhance product
traceability. The CS family comes in multiple EEPROM array densities from 1Kb
through 64Kb.
As an application’s needs grow over time and greater memory densities are
required, the 128-bit Serial Number contained within any CS series Serial EEPROM
product remains unique, enabling the value to remain distinctive across the entire
portfolio of customer applications.
The AT24CS series maintains all of the features that make serial EEPROMs a must-have element in most designs,
including 1 million cycle write endurance, 100-year data retention, byte write capability, and very low active and
standby current consumption.
Packages Available for CS and MAC Series Serial EEPROMs
Feature Benefit
Pre-programmed 128-bit Serial Number Enhanced product traceability
Serial Number is read-only Impossible to alter or change the Serial Number
Serial Number is stored in a separate memory area Does not reduce the user portion of memory array
Serial Number is accessed via a separate device address Product acts as two separate devices on the bus
Serial Number is unique across all products regardless of density or family Number uniqueness across all customer platforms or applications where the
CS series product is used

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
Feature Benefit
Unique pre-programmed MAC/EUI address No need to manage a database of MAC/EUI addresses
Permanent and reversible EEPROM write protection Ability to store and protect other system-vital information like lot number,
revision, manufacturing location, etc.
Pre-programmed MAC/EUI address does not consume any of the user
EEPROM area Entire EEPROM array is available for use
Pre-programmed, true EUI-64 addresses available True EUI-64 address available instead of converting a 48-bit value for use
in a 64-bit system
Pre-programmed, read-only 128-bit Serial Number Enhanced product traceability
Unique serial number across all Atmel MAC and CS series devices
