Application

The PN531 is tailored to fulfil the requirements of various applications using contactless communication based on the ECMA340 (NFC IP-1) Interface and protocol standard, the ISO14443A reader and FeliCa reader protocol. NFC IP-1 is also standardised in ISO/IEC 18092.

Compatible to current RFID infrastructure the NFC technology offers a new direct communication link between two NFC enhanced devices. This peer-to-peer communication enables a direct data exchange between devices.

The integrated microcontroller and embedded firmware of the PN 531 means a fast and easy integration in a contactless system. The high-level abstraction commands and the complete handling of RF communication protocols free the host CPU of all real time related constraints.

NFC technology is designed to meet requirements for consumer markets, as well as handheld and PC markets.

Typical devices to integrate the PN531 are
• Mobile phones
• PDAs
• PCs
• Intelligent remote controls
• PC peripherals e.g. printers and mice
• Consumer electronic devices like digital cameras
