The Infineon AIROC UWB TSL100 represents a massive leap forward in the realm of wireless connectivity and secure digital access. Officially introduced by Infineon Technologies AG, this first-generation ultra-wideband (UWB) semiconductor product family is engineered specifically to deliver highly precise positioning and smart presence detection entirely on a single chip. As smart devices, connected vehicles, and automated industrial environments become increasingly intertwined, the demand for secure, low-latency, and low-power spatial awareness has skyrocketed.
As an integral addition to the expanding AIROC portfolio, the newly launched chip features a radically optimized architecture. It is purpose-built to drastically minimize power consumption while elevating security standards to unprecedented heights. Designed with scalability in mind, the platform is future-proofed to support upcoming industry protocols such as IEEE 802.15.4ab. Furthermore, it operates in full compliance with major global industry consortium standards, including the Car Connectivity Consortium (CCC), Aliro, and FiRa. By merging ranging and sensing capabilities into a single integrated circuit, Infineon is setting a new benchmark for seamless connectivity on Aarokatech.com and across the global tech landscape.
Transforming Secure Access and Indoor Navigation
Modern access systems—whether for vehicles, smart buildings, or sensitive industrial sites—demand absolute reliability. The integration of ranging and sensing within the Infineon AIROC UWB TSL100 allows manufacturers to eliminate the need for redundant, separate sensing subsystems. This consolidation not only reduces the physical footprint of the hardware but significantly cuts down on overall system complexity and manufacturing costs.
The potential applications are vast and transformative. In the automotive sector, this technology seamlessly powers secured vehicle access and advanced in-cabin presence detection. For consumers and enterprises, it facilitates frictionless access control, rapid contactless payments, transit ticketing, and highly accurate indoor navigation. Industrial sectors also benefit immensely, utilizing the chip for real-time asset tracking and heavy machinery collision avoidance, ensuring a safer and more efficient operational workflow.
Conquering Security Threats and Environmental Obstacles
One of the greatest challenges in wireless access technology is maintaining a robust radio frequency (RF) performance in non-line-of-sight environments. A classic example is the “back-pocket scenario,” where a user’s smartphone or digital key fob is obstructed by the human body or thick fabrics. The Infineon AIROC UWB TSL100 excels in these difficult conditions by utilizing an excellent first-path dynamic range that effortlessly resolves signal obstructions without draining the battery.
Security is another critical frontier. Digital keys and smart locks are prime targets for sophisticated cyber threats, notably man-in-the-middle relay attacks. To combat this, users and network administrators require the highest possible cryptographic standards. This ultra-wideband solution integrates provable physical-layer and application-layer security, guaranteeing that proximity data cannot be spoofed or intercepted, thereby keeping vehicles and properties strictly off-limits to unauthorized entities.

Tailored Solutions: The TSL111A and TSL111C Variants
Understanding that different industries have unique regulatory and performance requirements, Infineon has split the product family into two specialized variants:
The Automotive Variant (TSL111A)
Built to withstand rigorous automotive environments, the TSL111A is AEC-Q100 qualified, making it the perfect choice for Original Equipment Manufacturers (OEMs) and Tier-1 automotive suppliers. It is specifically optimized for CCC Digital Key integrations, smart key fobs, and crucial safety features like NCAP-compliant child presence detection. Additionally, it empowers convenience features like hands-free trunk kick sensing and robust vehicle intrusion detection.
The Consumer and Industrial Variant (TSL111C)
Aimed at the broader commercial market, the TSL111C is the engine behind next-generation smart access control systems. It is highly effective for global asset tracking, tap-free point-of-sale payments, and smart tag “find my device” networks. Its precise indoor navigation capabilities make it ideal for guiding users through complex indoor spaces like airports, shopping malls, and massive warehouses.
Core Advantages of the Integrated UWB Architecture
Implementing the Infineon AIROC UWB TSL100 yields several distinct engineering and operational benefits that directly translate into a superior end-user experience:
- Exceptional Battery Efficiency: The highly optimized low-power design allows standard coin-cell batteries inside key fobs to easily exceed a two-year lifespan, even when utilizing continuous CCC ranging schemes. Furthermore, a specialized low-power sleep mode cuts ambient current consumption by more than 50 percent compared to legacy solutions.
- Military-Grade Security Protocol: The physical layer (PHY) design achieves the maximum 48-bit FiRa and CCC security levels. It is so sensitive and secure that it can accurately detect and verify weak direct signal paths that are up to 100,000 times fainter than surrounding reflected signals.
- Cost-Optimized System Sensing: The internal RF architecture inherently supports high-end sensing functions. This makes deploying advanced scenarios—like kick sensing or NCAP cabin monitoring—much more affordable by relying entirely on the single UWB chip rather than an array of distinct sensors.
- Intelligent AIROC Zoning: Powered by proprietary intent detection technology, AIROC Zoning creates highly configurable spatial unlock zones. It can accurately determine whether a user is inside or outside a specific boundary, ensuring that Aliro-enabled smart locks respond reliably while conserving battery life.
Accelerating Development and Market Availability
To help engineers and developers bring their innovations to life faster, Infineon is heavily supporting the rollout of this new platform. Dedicated engineering sample kits are currently available upon request. These comprehensive kits grant developers unrestricted access to evaluate system-level metrics, test ranging accuracy, map sensing coverage, and monitor real-world power consumption. By streamlining the hardware and software co-development process, manufacturers can significantly reduce their time-to-market for the next wave of secure, UWB-enabled smart devices.
