NCF3340AHN/00300Y

The NCF3340 is ideally suited for easy integration of NFC technology into automotive devices because it provides an NCI interface, a small PCB footprint, a small external BOM, and the capability to achieve RF standards (NFC Forum, EMVCo card) with a small form-factor antenna. It uses an optimized architecture for low power consumption and integrates a highly efficient power management unit. It supports high output power by supplying the transmitter output stage up to 5.5 V. This enables a large operating distance in Reader/Writer mode. The contactless front-end has high sensitivity and can work in active load modulation communication, so it can support a small antenna. The device ships in a 40-pin HVQFN package with wettable flanks.
