A closer look at Atmel’s AT24CS Serial EEPROM

Yesterday, Bits & Pieces got up close and personal with Atmel’s AT24MAC family which provides a pre-programmed MAC address inside of a serial EEPROM device – without consuming any user memory area.

And today we will be taking a closer look at Atmel’s AT24CS Serial EEPROM. Simply put, practically 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,” an Atmel engineering rep told Bits & Pieces.

“However, 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.”

And that’s precisely why Atmel’s AT24CS lineup of devices includes a unique, factory-programmed, read-only 128-bit serial number to help engineers simplify inventory control of mass production lines, all while enhancing product trace-ability.

“The CS family comes in multiple EEPROM array densities from 1Kb through 64Kb,” the Atmel engineering rep continued. “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 applications.”

As expected, the AT24CS series maintains all of the features that make serial EEPROMs a must-have element in most designs, including one million cycle write endurance, 100-year data retention, byte write capability, along with very low active and standby current consumption. Plus, the read-only serial number is stored in a separate area and does not reduce the user portion of  the memory array.
