Mouser now stocks the PN7642 single-chip NFC solution from NXP Semiconductors.

The device includes a high-performance, NFC Forum-certified NFC reader with 2W output power. The integrated, customisable Arm Cortex-M33 MCU includes 180kB flash, 20kB RAM and a rich set of controller and host interfaces. The product consists of SESIP-Level 2 certification, a complete security toolbox, crypto accelerators, and secure key storage, all supported by software.

The product is a versatile solution that replaces the necessity for an extra MCU and dedicated Secure Element. A range of controller and host interfaces and comprehensive product support packages facilitate a fast design-in.

Applications for the single-chip NFC solution include secure physical access control, such as smart door locks, doorbells, and electronic lockers, secure authentication of consumables and accessories, medical devices, trusted ID readers, and other secure contactless data communications.
