UWB SoC provides precise distance measurement
Infineon’s AIROC UWB TSL100 SoC enables centimeter-level distance measurement and localization using ultra-wideband (UWB) time-of-flight (ToF) technology. Designed for low-power, secure operation, the device targets automotive, consumer, and industrial applications such as secured vehicle access, in-cabin presence detection, contactless payment and ticketing, and industrial asset tracking and collision avoidance.
The TSL100 is the first member of a scalable UWB product family intended to align with upcoming standards such as IEEE 802.15.4ab. It includes a CCC-, FiRa-, and Aliro-compliant MAC. The PHY delivers 48-bit FiRa and CCC security in challenging non-line-of-sight conditions, detecting and verifying direct paths up to 100,000 times weaker than reflected paths.
The SoC enables more than two years of coin-cell battery life in CCC ranging schemes for key fobs, achieved through a dedicated low-power mode that reduces current consumption by more than 50%. Its RF architecture extends sensing functions to presence detection, kick sensing, intrusion detection, and NCAP scenarios. Additionally, AIROC zoning technology enables configurable unlock zones and inside/outside detection for Aliro-enabled smart locks.
Engineering sample kits for the AIROC UWB TSL100 are available upon request.
