Please check the new online NFC Antenna Tool for tag and reader devices.

If you need high NFC performance or the lowest power consumption, use this remarkably efficient yet highly flexible frontend family to push your design further. It offers an extended temperature range, pin-to-pin compatibility within the CLRC663 plus family (see table below), and time-saving software tools. Supporting, among others, MIFARE^®, ISO/IEC 14443, ISO/IEC 15693, and ISO/IEC 18000-3m3, the CLRC663 plus family is the natural companion to match with NXP NFC tags.

The CLRC663 plus family is a great choice for NFC applications with high performance requirements: access control, gaming, and industrial.

A fast antenna design is supported by the NFC Antenna Design Hub, the PC based configuration tool "NFC Cockpit" enables simple configuration (e.g. RF register settings, DPC, AWC ) and compliance testing (EMVCo) of the device. The Feature complete software support library for NFC Frontend ICs, - the NFC reader Library - is designed to give developers a faster and simpler way to deliver NFC-enabled products.
