RFID (Radio-frequency identification) involves contact-less reading and writing of data into an RFID tag’s nonvolatile memory via an RF signal. Low frequency RFID devices typically consisting of a transponder (tag) and reader, with Atmel offering a broad range of contact-less products that allow manufacturers to more easily reach extensive vertical markets.
“Atmel’s transponders operate within the 100 to 150kHz bandwidth range, among others, while our RFID chips are suitable for the smallest devices and often require no external components, lowering your tag costs,” an Atmel engineering rep told Bits & Pieces.
“You can choose from a broad range of read or read/write devices, available as identification ICs (die on wafer, with optional gold bumps, or packaged die, e.g., micromodule, XDFN package) or as an entire transponder.”
According to the engineering rep, Atmel RFID tech supports industry-specific standards, such as ISO 11784/85 (FDX-B and FDX-A) for animal identification and waste management. Flexible modulation coding options allow chips to be easily configured to fit a broad array of modulation schemes including FSK, PSK,ASK, Manchester, Bi-phase, NRZ direct coding and more.
On the security side, Atmel R/W transponders contain a unique identification number (UID) with traceability code. And last, but certainly not least, Atmel’s self-contained demonstration kits include an LCD and control buttons, allowing engineers to easily interact with the RFID system. In short, source code, building blocks and reference designs help manufacturers quickly evaluate and prototype complete system-level designs.
