Infineon Technologies AG and Renesas Technology Corp., the world’s number one and number two suppliers of microcontrollers for smart cards, today announced that they will offer a common software interface for their 32-bit families of smart card microcontrollers. Such a standardised software interface will help to accelerate the development of new smart card applications, as it enables card manufacturers to re-use their application-specific software across various smart card IC platforms, which are widely used in mobile communications applications.
