If you need the best NFC performance or the lowest power consumption, use this remarkably efficient yet highly flexible frontend to push your design further. It offers an extended temp range, pin-to-pin compatibility to CLRC663 family (MFRC630 SLRC610), and time-saving software tools.

The CLRC663 plus is the perfect choice for NFC applications with high performance requirements: access control, payment, gaming and industrial.
