Infineon Introduces the AIROC™ UWB TSL100 for Precise Positioning and Smart Presence Detection on a Single Chip

The TSL100 combines ranging and sensing capabilities in a single device, enabling applications such as secured vehicle access, in-cabin presence detection, access control, contactless payment, ticketing, and indoor navigation, as well as industrial use cases including asset tracking and collision avoidance. With the introduction of the AIROC™ UWB TSL100, Infineon strengthens its position in secured connected systems and expands its AIROC™ wireless portfolio with a new family of UWB devices. These devices combine precise positioning and smart presence detection on a single chip, addressing growing demand across automotive, consumer, and industrial markets.

Vehicle and building access systems as well as asset tracking and indoor navigation require very low power operation, reliable and robust RF performance to resolve non-line of sight scenarios like back pocket situations. Moreover, users and administrators demand highest security levels to avoid man-in-the-middle attacks. “Our AIROC UWB portfolio addresses these challenges by combining low power consumption, excellent first-path dynamic range and provable physical- and application-layer security. As a result, the first-generation AIROC UWB TSL100 SoC enables seamless access, positioning, and sensing capabilities while reducing system complexity,” said Maurizio Skerlj, Senior Vice President Authentication and Identity Solutions at Infineon.

Enabling Secured Access and Digital Key Applications
The AIROC UWB TSL100 product family comes in two variants: the TSL111A (AEC-Q100) for automotive OEMs and Tier-1 suppliers, and the TSL111C for consumer and industrial applications. The automotive variant targets use cases such as CCC Digital Key™, key fobs, NCAP-compliant presence detection, kick sensing, and intrusion detection, while the consumer and industrial variant supports smart access, asset tracking, tap-free payment, “find” applications, and indoor navigation. The integration of ranging and sensing on a single device reduces system complexity by eliminating the need for separate sensing subsystems in many applications.

The AIROC UWB TSL100 offers the following key advantages for UWB implementations:

• Low power consumption: A low-power design achieves coin-cell battery lifetime of more than two years in CCC ranging schemes for key fobs. A dedicated low-power mode further reduces current consumption by more than 50 percent.
• Efficient Security: The PHY design enables highest FiRa/CCC security levels (48-bit) in challenging non-line-of-sight conditions, such as back-pocket scenarios. The system can detect and verify the security status of weak direct paths up to 100,000 times weaker than reflected paths.
• Cost-Optimized Sensing: The RF architecture supports sensing functions for applications such as presence detection, supporting NCAP scenarios as well as kick sensing and intrusion detection.
• AIROC Zoning: AIROC intent detection technology provides a system-level solution for configurable unlock zones as well as inside/outside detection for reliable access control performance while extending battery life for Aliro-enabled smart locks.

The AIROC UWB TSL100 will be supported by an engineering sample kit that provides developers with access to Infineon’s latest UWB technology for rapid prototyping of secured access and sensing applications. The kit supports system-level evaluation, including ranging accuracy, sensing coverage, and power consumption, and helps accelerate hardware and software co-development, reducing time-to-market for next-generation UWB-enabled products.
