Atmel Serial EEPROM Products Featuring the broadest array of product families and package offerings Serial EEPROMs: Flexible and Robust Nonvolatile Memory Devices Atmel is a worldwide leader in the design and manufacture of microcontrollers, capacitive touch solutions, logic, mixed-signal, nonvolatile memory, and RF components. Leveraging one of the industry’s broadest intellectual property technology portfolios, Atmel is able to provide the electronics industry with complete system solutions focused on industrial, consumer, security, communications, computing, and automotive markets. Atmel® nonvolatile memory products offer our customers a broad range of memory densities and package styles and are accessed through the industrystandard serial interface bus architectures commonly used in today’s electronic systems. Serial EEPROM devices are by far the most popular vehicle utilized in today’s modern electronic equipment to store personal preference and configuration data. Applications span a wide spectrum of consumer, automotive, telecommunication, medical, industrial, and computing applications. This popularity stems from a unique combination of capabilities that cannot be found in any other memory solution. These features include byte-write alterability, nonvolatile data storage, 1 million cycles of write endurance, very low power supply voltage operation, 100 year data retention, low pin-count packages, low cost of ownership, and extremely low active and standby currents. The Atmel Serial EEPROM portfolio supports industry-standard I2C, Microwire and SPI protocols. These devices are available in a variety of product versions, including industrial temperature range, automotive grade, CS Series (Serial Number), MAC Address, and Application-Specific.

Atmel Serial EEPROMs are flexible, low-cost nonvolatile memory devices that provide system designers with a variety of features and performance characteristics to improve their designs. Atmel offers devices available with three different industry-standard serial interface protocols to give designers a wide range of choices to meet their particular system requirements. I2C-compatible (2-wire) Simple interface, yet the most popular choice for various microcontroller, microprocessor, and system-on-a-chip (SoC) solutions. I2C devices support cascading of up to eight Serial EEPROMs on the same bus and offer varying types of write protection. SPI-compatible High-speed interface with operation of up to 20MHz. SPI devices feature advanced hardware and software write protection schemes with operating voltages as low as 1.7 V. Microwire-compatible (3-wire) Simple interface with support up to 2MHz. Microwire devices offer user-selectable x8 or x16 memory organization with software write protection to secure data integrity. Application specific Addressing high-volume applications with unique requirements. These devices target support for the JEDEC required Serial EEPROM functions in the DIMM module market.

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 Atmel CS series Serial EEPROM product remains unique, enabling the value to remain distinctive across the entire portfolio of customer applications. The Atmel 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. 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 Learn more at the CS Series Serial EEPROM Website 4 © 2015 / www.atmel.com Atmel Serial EEPROM Products Featuring the broadest array of product families and package offerings Atmel AT24MAC Series Serial EEPROM EEPROM Memory Array 128-bit Serial Number 48- or 64-bit MAC Address Control Logic Device Address ‘1010’ Device Address ‘1011’ Data Buffer I/O Interface WP, A2, A1, A0 SCL, SDA 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. One can now find bathroom scales with integrated Wi-Fi connections that log and record your weight to track how closely you are towards meeting your goals. Refrigerators now have touch screens on their doors that effectively are integrated tablet computing devices. 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 tedious. The Atmel AT24MAC family alleviates this burden by providing a pre-programmed MAC address inside a Serial EEPROM device, without consuming any user memory area. By utilizing the new Atmel 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 Atmel AT24MAC series makes it simpler, faster and less expensive to develop Internet-connected products. Based upon proven and robust Atmel Serial EEPROM technology, the Atmel 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 MAC address functionality to their design. 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 such as 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 Enhanced product traceability Pre-programmed, read-only 128-bit serial number Unique serial number across all Atmel MAC and CS series devices Learn more at the MAC Series Serial EEPROM Website Atmel Serial EEPROM Products 5 Atmel Automotive-Grade Serial EEPROMs The best way to build a zero defect automobile is to build it from the ground up with zero defect components.
