Trimension SR048: Industrial‑Grade UWB SoC

High-Precision RTLS for Industrial Positioning

The NXP Trimension SR048 is an industrial-grade ultra-wideband (UWB) SoC designed for high-precision real-time location systems (RTLS) in industrial environments. Built for both UWB tags and anchors, it enables accurate indoor positioning for applications such as asset tracking, factory automation, and industrial IoT.

Accurate Indoor Positioning with UWB

The SR048 delivers reliable positioning performance using multiple UWB ranging methods, including Time Difference of Arrival (TDoA), Reconstructed Time of Flight (RToF), and TsToF. This ensures precise tracking of assets, tools, and personnel in complex environments such as warehouses, production lines, and logistics hubs.

Scalable RTLS Architecture

Designed for large-scale deployments, the SR048 supports uplink TDoA, where tags transmit short signals while anchors perform positioning calculations. This reduces power consumption and allows battery-powered UWB tags to operate efficiently, even in dense industrial RTLS systems.

Fast Development with Integrated System Design

The SR048 integrates seamlessly with NXP MCX W72 MCUs, forming a two-chip solution that accelerates development of omlox-based RTLS systems. This system-ready approach reduces integration effort, shortens time-to-market, and enables interoperable, standards-based positioning solutions.

Industrial-Grade Performance

Engineered for harsh environments, the SR048 operates reliably from -40°C to 115°C. Its low-power design supports compact, battery-powered devices, making it ideal for industrial IoT and smart factory applications.

Future-Proof RTLS with Open Standards

The SR048 supports omlox-compatible RTLS, enabling multi-vendor interoperability and long-term system flexibility. As part of NXP’s Trimension UWB portfolio, it provides a solid foundation for scalable, future-ready indoor positioning solutions in Industry 4.0 environments.
