Serial EEPROMs

19 September 2012 DSP, Micros & Memory

Two new families of serial EEPROM products have been introduced by Atmel, with the intention of simplifying the design and lowering the cost of Internet-connected products, thanks to their unique identifiers.

The AT24MAC series of devices provide pre-programmed media access control (MAC)/extended unique identifier (EUI) node identity addresses, alleviating the need for customers to program their own MAC/EUI addresses and maintain the associated complex databases.

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 new ICs can be used in a variety of market segments besides Internet-connected devices, such as 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 AT24MAC602 devices provide unique, pre-programmed 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 utilise 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.
