Introduction

Atmel offers several design and evaluation kits for a fast and easy way to test the LF-RFID technology but also developing the final product. The most important one is the Atmel ATA2270-EK3. It provides a complete self-contained tool to begin using RFID systems, even for users who are short on RFID experience. It supplies an LCD and control buttons to enable interaction with the RFID system. This stand-alone but also PC-GUI based system supports many of Atmel's RFID tag chips. The second group of kits is based on two readers supplied by an external company. One of them is working at 125kHz (Atmel ATARFID-EK1) the other one at 134.2kHz (Atmel ATARFID-EK2) targeting access control applications and animal ID applications. Third kit is the Atmel ATA6286-EK3. The evaluation kit for Atmel’s active RFID solution. This works at 2 frequency bands: 125kHz and 433MHz.

The Atmel ATA2270-EK3 is an evaluation kit that supports a limited number of configurations in stand-alone mode. Support during the entire development phase is provided by the PC interface and the application software. Both tools enable full control of the tag configuration. This kit is AVR ATmega128-based and provides all necessary source and object codes. An API (Advanced Programming Interface) allows control of the kit by user-written software. Registered kit users have access to an Atmel FTP server for firmware and software upgrades and also layout data in Gerber format with BOMs.

The Atmel kits ATARFID-EK1 and ATARFID-EK2 are based on a commercial reader/programmer supplied by the company GIS. The first version in the EK1 kit operates at 125kHz. It is best suited for access control, industrial, and any kind of consumer applications. This kit supports the very common Manchester and Biphase data coding but also FSK data coding. The EK2 kit operates at 134.2kHz according to the animal ID standards ISO 11784 and 11785 (FDX-A and FDX-B). Both kits allow the user to not only read the tags but also configure and program them. The readers have a USB connection and a PC-based user interface. Sample tags complete this kit.

The Atmel ATA6286-EK3 is a complete system evaluation kit for active RFID applications. Typically these are identification applications where a larger operating distance and/or a higher amount of data storage space is required compared to passive RFID solutions. The difference to a passive RFID system is that the tag ASSP is supplied by a battery in the tag. Also, the ASSP is not state-machine-based but uses an Atmel AVR MCU core. Atmel's active RFID system uses a unique combination of two different frequency bands: low frequency at 125kHz for the trigger and activation channel as well as for the data downlink path, and ultra-high frequency at 434MHz for the return and uplink path.
