LOCALIZATION WITH UWBTRIMENSION SR150 FOR IOT DEVICES AND ANCHORSThe fine ranging and positioning capabilities of UWBtechnology bring precise location and convenience to avariety of use cases, including secure access control, indoor
positioning, and device-to-device communication for item
tracking and tag location.

The Trimension SR150 IC is both forward and backward
compatible with IEEE 802.15.4z HRP UWB. The 500-MHz
bandwidth, with a pulse rate of 2 ns, supports high-resolution
ranging, with LoS accuracy within a range of ±10 cm. The Tx
peak power is more than +10 dBm and the receiver noise
figure is +4 dB.

UWB securely determines the relative position of peer
devices with a high degree of accuracy. The use of a
wideband spectrum means UWB uses little power to send
signals and provides stable connectivity with minimal
interference.
ACCURACYUWB delivers spatial awareness, which is a new dimensionof information. Knowing, where a device is, relative to
one-self, with extreme level of accuracy provides locationcontext. Compared to other wireless technologies, including
Wi-Fi® and Bluetooth®, which can narrow an item’s location
to within an area of about 150 cm under ideal conditions,UWB has a location accuracy of 10 cm, and requires fewer
anchors to cover the same area.
UWB can be used outdoors to locate objects very precisely,
down to the centimeter level, and can be used indoors,
where GPS has difficulty operating, to extend navigation
capabilities.

Delivered in a WLCSP68 package, the Trimension SR150
has, at its core, an Arm® Cortex®-M33 CPU with TrustZone®.
Integrated security hardware accelerators protect overall
operation for high-level RF security. A dual-Rx antenna
setup enables two channels for AoA functionality, and an
onboard CoolFlux® BSP32 DSP is used for ToF, AoA, andradar algorithms.
Building on IEEE 802.15.4z, the Trimension SR150 IC comeswith an added level of security, especially when used foraccess control to protect the privacy that comes with theexchange of access credentials. The added protections makethe Trimension SR150 IC more resistant to attempts to trick
the system, in what’s known as a relay attack, where hackersattempt to intercept and amplify the wireless signal andthereby open a lock, even though the key is not close by.
Several Trimension SR150 IC devices can be placed in aroom as UWB anchors to help localize people and objects
as they move within the room.

TRIMENSION SR150 + EDGELOCK SE051W FORSECURE USE CASES
NXP simplifies the development of secure UWB solutionsby offering pre-integration with the EdgeLock SE051W eSE.
Cryptographic binding of the eSE and the Trimension SR150
takes place in the customer’s factory, by setting up a securechannel between the EdgeLock SE051W and the TrustZoneof the Trimension SR150’s Cortex-M33. This prevents physicalunbinding and ensures all communication is protected. Keysto set up the secure channel never leave the eSE or theTrustZone. Key generation for dynamic scrambled time stamp
takes place in the eSE, while the dynamic STS generation
happens in the Cortex-M33 TrustZone. The EdgeLock SE051W
can also be shared with other IoT applications running in thedevice, such as secure cloud onboarding, device-to-device
authentication, device integrity protection, attestation andproof-of-origin.
SR040 FOR BATTERY OPERATIONThe Trimension SR040 is a specialized IC for battery-operated
IoT devices, including UWB trackers and tags and works withwith small batteries such as a CR2032 coin cell.
COMPREHENSIVE SOFTWARE SUPPORTNXP supplies all the firmware and middleware needed todevelop an application that can run UWB autonomously. That
includes a complete PHY and MAC implementation (not justthe UWB modem). All the complexity of PHY/MAC operationis handled within the UWB IC, so there is no need for realtime interaction from the host processor or microcontroller.
Communications between the host and the UWB IC are
governed by a FiRa-standard UWB command interface (UCI)running over SPI.

UWB MODULES
Trimension SR150 and Trimension SR040 ICs are available
in easy-to-integrate modules supplied by NXP partners.
The various Trimension SR150 modules address specificuse cases and, as a result, will either include a standalone
Trimension SR150 IC or an Trimension SR150 IC with
Bluetooth Low Energy and eSE integration, along withextensive software, documentation, and support packages.
Module development kits simplify the process of evaluating
UWB technology in key use cases, and make it easy toleverage the proven hardware design and flexibility ofcustom antenna configurations. Also, our Trimension SR150and SR040 UWB chips have been MFi certified to beinteroperable with the Apple U1 chip in Apple devices.
FIRA CERTIFIED
NXP is a founding member of the FiRa Consortium, acollaboration designed to grow the ecosystem for UWBtechnology so new use cases for fine-ranging capabilities
can thrive. Our deep involvement with the FiRa Consortium
not only gives us a leading role in FiRa activities—such as
the development of interoperability standards, expansion of
the UWB ecosystem, and the pursuit of new use cases—it
also ensures that our UWB solutions are both interoperable
and state-of-the-art.
