NFC prepares HCI spec

Keywords:control interface  HCI specification  NFC Forum 

The NFC Forum has started developing a specification for a host controller interface (HCI) between NFC contactless controllers and electronic devices' application processors, targeted to be released in 2008.

The aim is a logical interface that will allow an NFC front end to communicate directly with an application processor and multiple secure elements in various electronic devices such as cell phones, PDAs and PC peripherals, enabling faster integration of NFC functionality.

The HCI will cover all NFC operational modes, including reader/writer, peer-to-peer and card emulation. The companies and standards bodies involved aim to ensure that it will be possible to implement the final specification over a wide range of physical interfaces, including SPI bus, I?C, UART, USB and others.

The interface between the NFC controller and the integrated circuit card (UICC) or SIM card is being specified by the European Telecommunications Standards Institute and is outside the scope of the Forum's HCI specification work.
