NXP has announced a new development platform for hands-free, automated access to homes and secure areas, leveraging ultra-wideband technology for secure automated access control. The Autonomous Secure Access Solution allows users to approach a door to unlock it without needing a keypad, app, or button.
The solution works with users’ smartphones to create a seamless, secure entry platform similar to automobile keyless entry systems. The system connects to a phone and senses when it is in close proximity, unlocking the door once identified.
The development kit is built around the NXP FRDM development platform, featuring an MCX W71 Arm Cortex-M33 processor and an Arduino-compatible shield with a UWB chip, NFC, and security chip. The Trimension SR150 chip supports ultra-wideband technology, determining precise position and verifying authorization.
The platform leverages NXP’s Edgelock SE051 security chip, certified to CC EAL 6+ with AVA_VAN.5, and supports the Connectivity Standards Alliance’s (CSA) Aliro standard for secure home access. The Aliro standard ensures consistent, secure interoperability between devices.
The NXP access solution is sampling now and scheduled for full availability in the second half of 2025, making it one of the first solutions to use UWB technology for hands-free, walk-up unlocking capability.
