June 30, 2026 /SemiMedia/ — Infineon Technologies has introduced the AIROC™ UWB TSL100, its first-generation ultra-wideband product family for precise positioning, smart presence detection and secure access applications.

The TSL100 is part of Infineon’s AIROC wireless portfolio and uses a new architecture designed to reduce power consumption and improve security. The product family combines ranging and sensing capabilities in a single device.

The chip targets applications including secured vehicle access, in-cabin presence detection, access control, contactless payment, ticketing, indoor navigation, industrial asset tracking and collision avoidance.

Infineon said UWB is becoming an important wireless technology for connected vehicles, smart locks, wearables and industrial positioning systems. By enabling accurate ranging and spatial awareness, UWB can help systems determine device location, movement and user intent more reliably.

The AIROC UWB TSL100 family includes two variants. The TSL111A is AEC-Q100 qualified and designed for automotive OEMs and Tier 1 suppliers. The TSL111C targets consumer and industrial applications.

The automotive version supports CCC Digital Key™, key fobs, NCAP-related presence detection, kick sensing and intrusion detection. The consumer and industrial version supports smart access, asset tracking, tap-free payment, “find” applications and indoor navigation.

Infineon said secure access systems require low power consumption, robust RF performance and strong protection against man-in-the-middle attacks. The TSL100 is designed to support reliable ranging in non-line-of-sight scenarios, including cases where a device is carried in a back pocket.

The device’s physical-layer design supports high FiRa and CCC security levels and can detect and verify weak direct paths, helping improve security in difficult RF environments.

Power consumption is another focus. Infineon said the low-power design can deliver more than two years of coin-cell battery life in CCC ranging schemes for key fobs. A dedicated low-power mode can further reduce current consumption by more than 50%.

The product family also supports Infineon’s AIROC Zoning intent detection technology, enabling configurable unlock zones and inside/outside detection for access control systems while helping extend battery life in Aliro-enabled smart locks.

The TSL100 is designed as a scalable UWB platform intended to support future standards such as IEEE 802.15.4ab. It is also compliant with industry consortium standards including CCC, Aliro and FiRa.

Infineon will support the AIROC UWB TSL100 with an engineering sample kit for rapid prototyping. The kit allows developers to evaluate ranging accuracy, sensing coverage and power consumption while accelerating hardware and software co-development.
