Atmel Corp. announced the availability of a low-frequency (LF) one-time programmable (OTP) transponder IC, the Atmel IDIC ATA5575M2, optimized for next-generation animal identification systems for pets, wildlife or livestock. The device can also be used for waste management applications according to the BDE standard (see footnote).
The ATA5575M2 OTP functionality aims to simplify the production process. Before shipping, OEMs can program into the device any necessary information, including the specific country or the manufacturer code supplied either by the International Committee for Animal Recording (ICAR) or government authorities. Atmel reports that this reduces lead-time and time to market down to approximately 1 to 2 weeks.
The integration of optional trimmed 250-pF or 330-pF on-chip capacitors can reduce system cost. These capacitors eliminate the need for external components because a coil is all that is needed for a complete system, thus enabling extra-small access control applications. At approximately 0.9 square millimeters, the Atmel ATA5575M2 can be used in most transponder packages, including glass transponders or plastic key housings for very small tags (such as animal tags).
The memory in the device contains a unique manufacturer-programmed ID which the user can overwrite with a specific animal ID code. The user ID (UID) can be read and archived (along with the animal code) before programming to ensure reliable traceability.
Since an LF device operates in the range of 100kHz to 150kHz, the Atmel ATA5575M2 can be used worldwide. It is designed for rugged environments and can also be used in conditions not typical for RFID application devices, including underwater (fish tagging), in dirt (outdoor livestock), or injected via glass or plastic transponders (under the skin of animals) for tracking purposes.
The ATA5575M2 transponder IC supports the FDX-B and FDX-A standards:
- FDX-B: ASK modulation, 128 bits, differential Biphase coding with a fixed bit rate of RF/32
- FDX-A: FSK modulation, 96 bits with a fixed bit rate of RF/50
It can replace nearly all available LF RFID read-only devices that conform to the ISO 11784/85 standard in FDX-B mode.Price and Availability
Samples are available now on wafer or die-in-waffle pack. Pricing for wafer shipments of the Atmel ATA5575M2 starts at US $0.34 in quantities of 15,000. Evaluation kit (ATA2270-EK1) is based on Atmel's AVR® microcontrollers and is accompanied by Windows® PC software, C-source code for the AVR and PCB Gerber data for the reader board.Footnote
