Atmel and Melexis Microelectronic Integrated Systems announced an innovative development kit, Yuma+, for contactless, highly secure RFID transactions. The Yuma+ solution is based on Atmel's secure CryptoRF chips, with 64-bit embedded cryptographic engines, Atmel's AVR microcontroller and the Melexis MLX90121 reader IC.
With the Yuma+ kit, developers of secure RFID systems do not require an in-depth understanding of the complex details of cryptography in order to deploy secure host-client RFID systems that depend on mutual authentication and data encryption. This solution also eliminates the need to delve deeply into the details of the ISO14443B RFID standard, providing a fully turnkey reader and tag solution.
Yuma+ includes a module board and an interface board. The module board, which contains an AVR ATMega168 microcontroller, an MLX90121 RFID transceiver chip and simple SPI connectivity is internally matched to connect to any 50 Ω antenna for incorporation into any system. The interface board connects to a PC through USB to provide an evaluation platform for the module. Yuma+ also comes with an assortment of CryptoRF tags, software CD with schematics, board layout files and a binary image of the firmware for quick and easy integration.
