NXP Semiconductors has launched its PN7642, a single-chip connected microcontroller (MCU) that integrates an Arm Cortex-M33, an NFC reader and SESIP-Level 2 security. Together, these features help deliver faster and more secure NFC transactions. Target applications for the connected MCU include physical access solutions, consumables authentication, secure identity verification and other NFC use cases.
“NFC has become an essential element for secure authentication, for both people and goods,” said Alasdair Ross, senior director, NFC IoT Security, NXP, in a statement.“ By combining a customizable 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 PN7642 consists of a high performance NFC Forum-Certified NFC reader with 2-W output power, supporting read/ write and card emulation modes, and an integrated customizable Arm Cortex-M33 MCU that includes 180-kB flash, 20-kB RAM and a range of controller and host interfaces. For security, the connected MCU includes SESIP-Level 2 certification, a complete security toolbox, crypto accelerators and secure key storage, all supported by software.
Other features include a power supply from 2.4 V to 5.5 V, support for ECP 2.0 and ultra-low-power card detection (22-µA type). The PN7642 also integrates a DC/DC that allows for a single 3.3-V supply with maximum transmit power.
The PN7642 is housed in a VFBGA64 package, measuring 4.5 × 4.5 × 0.8 mm. Applications include communication infrastructure, smart home appliances, smart locks and smart cities. The company is exhibiting at Embedded World, March 14-16, Nuremberg, Germany, in Hall 4A, booth #4A-222.
