austriamicrosystems has announced a solution, developed in cooperation with Infineon Technologies AG, that enables NFC (near field communication) data transfer on removable secure elements using a micro-antenna design. It will speed up the deployment and the acceptance of standalone NFC solutions based on ultra small form factors such as microSD.
Working in close technical cooperation, austriamicrosystems and Infineon leveraged their respective expertise to design solutions that combine an Infineon security contactless microcontroller with austriamicrosystems’ AS3922 RFID front-end chip. Infineon’s secure microcontrollers are certified according to the Common Criteria and EMVCo international standards and answers to the requirements of NFC Mobile Payment.
The AS3922, the result of the cooperation, supports an antenna booster technology to overcome the lack of reliability of the existing NFC microSD. Existing solutions only operate in a limited number of phones and over a very short distance. The NFC microSD solution is integrated with the micro-antenna included in the ultra small form factor. No other design approach currently on the market allows for reliable contactless payment fully enclosed within the microSD.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
