Trimension® SR150 Secure UWB Chipset

Secure UWB Solution for IoT Devices

The Trimension® SR150 from NXP Semiconductors is a highly secure ultra-wideband (UWB) chipset designed specifically for IoT devices and smart infrastructure applications. Built on NXP’s proven UWB platform, the SR150 combines precise ranging, enhanced positioning capabilities, and strong security features in a compact solution.

A key feature of the SR150 is the integration of Angle-of-Arrival (AoA) technology, which enables even higher positioning accuracy in real-world deployments. By determining not only the distance but also the direction of incoming UWB signals, AoA improves localization performance in environments such as buildings, smart spaces, and industrial facilities.

The chipset includes an integrated FiRa MAC layer, ensuring interoperability with a growing ecosystem of FiRa-compliant UWB devices. With firmware version 3.14.0, the SR150 also supports interoperability with devices equipped with the Apple U1 chipset, enabling integration with consumer products and mobile devices that support UWB-based spatial awareness.

The Trimension SR150 is designed for a wide range of infrastructure and IoT use cases. Typical applications include secure access control systems, indoor positioning solutions, and proximity-based payment systems. It is also suitable for consumer electronics such as smart TVs and gaming consoles, where spatial awareness and device proximity can enhance user interaction.

In indoor localization deployments, multiple SR150 chips can be installed as UWB anchors within a room or building. These anchors communicate with mobile devices or tags to track the real-time position of people and objects with high accuracy.

As part of NXP’s Trimension UWB portfolio, the SR150 benefits from a complete system-level approach that combines hardware, software, and security technologies. The platform integrates advanced security mechanisms based on NXP’s proven embedded secure element (eSE) technology, enabling trusted ranging and secure device interaction.

With its combination of precision positioning, interoperability, and built-in security, the Trimension SR150 provides a robust foundation for next-generation UWB-enabled IoT devices and smart environments.
