Atmel introduced two new families of Serial EEPROM products. The AT24MAC series of devices provide pre-programmed Media Access Control (MAC)/Extended Unique Identifier node identity addresses, alleviating the need for customers to program their own MAC/EUI addresses and maintain the associated complex databases, making it simpler, faster, and less expensive to develop Internet-connected products of all types. The AT24CS series of devices include unique, factory programmed, read-only serial numbers that can help customers simplify inventory control of mass production lines and enhance product traceability.
The Atmel AT24MAC and AT24CS devices can be used in a variety of market segments including Internet-connected devices, consumer, white goods, industrial, medical, communications, media, lighting, home automation, computing, telecom and security applications. The new devices are drop-in compatible with existing Atmel Serial EEPROM devices.
The new AT24MAC series devices have globally unique hardware addresses embedded onboard, so designers no longer need to absorb the management costs and time associated with acquiring, using, and managing an allotment of MAC/EUI addresses, defined by the Institute of Electrical and Electronics Engineers. The AT24MAC602 devices provide designers with unique, pre-programmed, industry-first 64-bit EUI addresses while the AT24MAC402 devices provide 48-bit MAC/EUI addresses. These addresses reside alongside a 2-Kbit Serial EEPROM. The AT24MAC602 device is well suited for use in applications that rely on ZigBee/IEEE 802.15.4, FireWire/IEEE 1394, and IPv6 for network communication. The AT24MAC402 device is ideal for a broad set of applications including those that utilize Ethernet, 802.11x wireless networking, and Bluetooth.
Both the AT24MAC series and the AT24CS series also contain Atmel-generated, unique 128-bit serial numbers. The serial numbers are exclusive regardless of memory density or product family, enabling the value to remain distinctive across the entire portfolio of customer applications. The AT24CS series of devices is initially available in densities of 1-Kbit to 8-Kbit denoted by the AT24CS01, AT24CS02, AT24CS04, and AT24CS08 part numbers.
