Secure and connected MCU enables faster NFC authentication

NXP Semiconductors has released the PN7642, a single-chip solution that combines a customisable MCU, an NFC reader and SESIP-Level 2 security to deliver faster, more secure NFC transactions for physical access solutions, secure identity verification, consumables authentication and other NFC use cases.

NFC technology has become fundamental to secure authentication, whether verifying that the person standing at a front door has been granted access by the homeowner or corroborating that the consumable inserted into a medical device is supported for use with that device.

“NFC has become an essential element for secure authentication, for both people and goods,” said Alasdair Ross, senior director, NFC IoT Security, NXP. “By combining a customisable MCU with an NFC Forum-certified NFC solution and a complete security toolbox, the PN7642 makes it easier to integrate NFC technology into new or existing secure authentication solutions.”

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