NXP Semiconductors has introduced two ultra-wideband (UWB) ICs for applications requiring fine range, high precision location sensing. The Trimension SR150 and SR040 ICs deliver relative position with high accuracy, well suited for smart locks, real-time location system (RTLS) tags and various IoT applications.

The Trimension SR150 provides angle-of-arrival (AoA) capability to increase precision. The SR150 is well suited for access control, indoor localization, payment and consumer electronics. Several of the ICs can be placed in a room to track moving people and objects.

For low power applications, the Trimension SR040 is designed to minimize power drain in battery-powered IoT devices, such as trackers and tags. It can be integrated with Bluetooth Low Energy and other connectivity standards. Supporting such applications, the Trimension OL23D0 is an open, programmable UWB controller, enabling users to program the device for the application.

NXP is sampling the SR150 and SR040 ICs now, and they will be available in volume by the end of the year. Modules and development kits will be available from NXP partners.

NXP sees UWB becoming the global standard for fine range and high precision sensing and has branded its family of UWB products “Trimension.” These new products, announced at NXP’s annual developer’s conference, add to its previously announced UWB products for mobile and automotive.

NXP says it was first to offer a system-level UWB solution backed by comprehensive software and strong security, based on its embedded secure elements and near-field communication integration. The family of Trimension UWB products expands NXP’s connectivity offerings beyond NFC, Wi-Fi, 5G and Bluetooth.
