Two new families of serial EEPROM products feature unique identifiers to simplify and accelerate the design of Internet-connected products. The AT24MAC series from Atmel Corp. provides pre-programmed media access control (MAC)/extended unique identifier (EUI) node identity addresses embedded onboard, eliminating the need for customers to program their own MAC/EUI addresses and maintain the associated complex databases.
The AT24CS family, meanwhile, includes unique factory-programmed, read-only serial numbers that can help customers simplify inventory control of mass production lines and enhance product traceability.
The AT24MAC602 devices offer 64-bit EUI addresses and are suited for use in applications that rely on ZigBee/IEEE 802.15.4, FireWire/IEEE 1394, and IPv6 for network communication. Providing 48-bit MAC/EUI addresses, the AT24MAC402 units target applications that use Ethernet, 802.11x wireless networking, and Bluetooth.
Both series contain built-in, exclusive Atmel-generated 128-bit serial numbers, which are unique regardless of memory density or product family. The AT24CS series initially comes in densities of 1-kbit to 8-kbit denoted by the AT24CS01, AT24CS02, AT24CS04, and AT24CS08 part numbers. Additionally, the new products are drop-in compatible with existing Atmel serial EEPROM devices.
Product samples are available now in 8-lead SOIC and 8-lead TSSOP packages; samples in the 5-lead SOT23 and 8-pad UDFN will be ready in the fourth quarter of 2012. The AT24MAC devices in 8-lead SOIC packages are available in production quantities for US $0.22 to $0.24 in 5,000-piece quantities, and the AT24CS devices in 8-lead SOIC are available in production quantities for US $0.20 to $0.25 in 5000-piece quantities depending on density.
