Atmel claims to have smallest RFID radio chip

Atmel has introudced a 363-bit read/write transponder for RFID tags in a very small XDFN package .

The transponder IDIC ATA5577M1 is a high-volume low-frequency (LF, 100-150kHz) RFID device designed for small tag applications including animal ID ear and bolus tags, standard key fobs or clamshell cards for access control solutions.

“Measuring at 2mm x 1.5mm x 0.37mm, the XDFN package is the world’s smallest RFID package available,” claimed the company.

The two coil wires can directly be soldered onto the two pads of the package and mounted or glued onto the antenna coil. The direct mounting and small packaging allows for extremely small end products since the resulting RFID tag size is determined by the size of the coil.

The package can also be soldered on a standard printed circuit board (PCB), for example, in combination with a PCB-mounted antenna. Since the chip has a 330pF on-chip capacitor trimmed to +/- 3%, the antenna coil is the only external component required to form a trimmed LF-RFID tag.

The incorporated ATA5577 chip provides a manufacturer-programmed and locked unique ID which enables the traceability of the product to prevent cloning or counterfeiting of the tag IC.

The unique ID and the extended read/write distances have been optimised for next-generation access control applications. The device also operates according to ISO 11784 and ISO 11785 (FDX-B) standards, making it well-suited for animal identification and waste management applications.
