NXP has introduced a new autonomous secure access solution designed to transform the smart lock and access control industry. This system-level platform integrates secure access and automation technologies, enabling manufacturers to develop and deploy optimized products with reduced complexity and faster time-to-market.
Streamlined Development for Smart Access
The solution allows smart locks to automatically recognize a user's smartphone and unlock without requiring manual interaction, such as unlocking the phone or opening an app. It provides a complete reference design for smart locks and access systems, combining hardware, software, and cloud-based configuration services. This enables manufacturers to customize products while ensuring interoperability with mobile ecosystems.
Core Components and Technologies
At the core of the solution is the FRDM-MCXW71 development board, powered by the MCX W7x series. It features low-power Bluetooth, embedded security zones, and support for Matter and Aliro standards. The system includes a Murata Arduino expansion board with a Murata Type 2JE module, integrating NXP's SR150 Trimension UWB for seamless access and the PN7642 NFC controller for tap-to-unlock functionality. The EdgeLock SE051 secure chip enhances security by protecting credentials against advanced hardware attacks.
The platform optimizes performance, power consumption, memory size, and stability while reducing bill-of-materials costs and simplifying form factor design. It supports indoor/outdoor detection and ensures compatibility with mobile ecosystems. The solution is scalable, incorporating secure access technologies like UWB and NFC, alongside automation-enabling protocols such as Thread, low-power Bluetooth, and Matter.
Future Enhancements and Interoperability
Future iterations of the solution will integrate Wi-Fi, capacitive touch interfaces, and support for MIFARE smart card products, widely used in residential, enterprise, and hospitality markets. The platform is extensible through the FRDM board ecosystem, supporting applications with higher memory demands or additional wireless capabilities via the RW612 tri-band wireless MCU.
The solution aligns with Aliro, a developing standard by the Connectivity Standards Alliance, which aims to standardize credentials and communication protocols for mobile and wearable device access. This enhances interoperability and security within smart home ecosystems.
Availability
The autonomous secure access solution is currently available as samples to customers, with mass production planned for the second half of 2025.
