Texas Instruments unveiled four integrated automotive chips in a virtual event, designed to reimagine in-cabin experience for both drivers and passengers. The high-tech chips were also showcased at the Consumer Electronics Show 2025 held in Las Vegas. The line-up included the AWRL6844 millimetre-wave radar sensor with AI-enhanced safety features, the AM275x-Q1 MCUs and the AM62D-Q1- a family of MCUs featuring the powerful C7X DSP core for premium audio- and the innovative TAS6754-Q1 audio amplifier with proprietary 1L modulation technology.

Alluding to the matter, a company official said, “The new-age automotive chips centre around advanced driver assistance systems (ADAS) and infotainment and cluster. As consumers, we expect a lot from our vehicles and this innovation is driven by two key factors. First, new government regulations and car assessment programmes mandate improvements in passenger safety, requiring more accurate and robust in-cabin sensing systems to monitor a variety of situations. Second, there is a growing demand for premium audio experiences as in-car systems now often surpass home audio systems in quality, delivering unparalleled experiences across a wide range of vehicles.”

“Our silicon solutions are designed to empower designers to enhance the overall in-vehicle experience without compromise. To that end, we are excited to debut three new automotive products,” he added.

Radar sensor

The AWRL6844 is designed to help customers deliver a safe and feature-rich user experience. It aims to enhance the user experience visually and improve safety. The company highlighted that OEMS face challenges in meeting stringent requirements while minimising cost and design complexity. Moreover, requirements for transference detection would award points only for direct sensing systems capable of detecting the presence of a human inside a vehicle by tracking signs of life such as artery aspiration rates and movements. Future in-cabin sensing systems would need to accurately differentiate between children and adults to enhance user experience and safety.

The AWRL6844 is the industry’s first single-chip solution that supports these three key applications, which has been achieved through the integration of AI into the silicon, claimed the company.

The sensor integration was said to provide optimal spatial resolution, delivering dense point cloud data for applications in a cost-effective manner while leveraging edge AI processing. This high-resolution data feeds into AI-driven algorithms on a customisable, on-chip auto accelerator and DSP, enabling local data processing. This approach, allows automotive systems to achieve advanced sensing with a single chip solution, reducing system cost and complexity.

The AWRL6844 will help OEMs could deliver seamless detection, validation and classification, simplifying sensing topologies and modalities used today or in the future.

For instance, the system can detect localised occupants with up to 98 percent accuracy to minimise detection errors. This eliminates uncertainty related to seatbelt detection when a non-human object is on the seat. When the car is parked, the sensor uses neural networks to classify adults and children with high accuracy, trained to detect micro-movements and distinguish between them. The device also enhances detection in blind spots, preventing children from being left unattended in vehicles.

Audio processor

On the other hand, the AM275x-Q1 MCU and AM62D-Q1 processors enable leveraging advanced audio features that enhance in-cabin experience. Another company official noted, “Audio is increasingly used in cars to enhance safety with features like door chimes and seatbelt reminders as well as to improve passenger comfort across vehicle fleets. These features are no longer limited to luxury vehicles. Our solutions bring premium audio capabilities across the entire OEM vehicle line-up, leveraging a unified software investment.” 

“At the core of this innovation our C7x DSP core. It supports a higher number of speakers and multiple audio zones, delivering high-quality sound throughout the vehicle. The C7x DSP achieves 4-8 times the processing performance of competing devices, enabling the management of multiple audio features within a single core, thus reducing the need for external components,” the official added.

The C7x DSP’s performance is made possible by its 256-bit vector architecture and single-cycle memory access, alongside pipeline optimisations that drive industry-leading audio benchmarks. Additionally, the integrated neural processing unit allows customers to develop and execute AI algorithms on the same platform. This high processing capability reduces component requirements for automotive audio systems while enabling advanced features like real-time tuning, spatial audio and latency-reduced ANC. 

“This is especially critical for EVs, which often lack passive sound-dampening materials, relying instead on active solutions to maintain cabin quietness. TI’s solutions also support Acoustic Vehicle Alerting Systems (AVAS) for external pedestrian alerts, making them integral to modern EV designs,” added the official.

The AM275x-Q1 MCU is a DDR-less single-chip solution tailored for high-performance audio applications, supporting up to 32 channels. Its integrated 4.5 MB SRAM and up to 6 MB L3 memory eliminate the need for external memory, reducing system complexity. In contrast, the AM62D-Q1 processor is DDR-based and suited for applications requiring large memory sizes such as high-resolution playback or simultaneous AI and audio processing. With a high-speed DDR4 controller, it ensures real-time compute capabilities and smooth performance. 

The company claimed that both chips will enable engineers to design premium audio systems with minimal investment in hardware and software. 

The TAS6754-Q1 Class D amplifier’s modulation technology reduces the number of required inductors by half. This advancement enables more compact, lightweight and cost-efficient designs without compromising audio quality. Additionally, the amplifier incorporates real-time load diagnostics, streamlining design processes and enhancing efficiency to meet OEM demands effectively.

Commenting on the new products, Senior Vice President of TI’s Embedded Processing Amichai Ron said, “Today’s drivers expect any car – entry-level to luxury, combustion to electric – to have enhanced in-cabin experiences. TI continues to provide innovative technologies to enable the future of the automotive driving experience. Our edge AI-enabled radar sensors allow automakers to make vehicles safer and more responsive to the driver, while our audio systems-on-chip elevate the drive through more immersive audio. Together they create a whole new level of in-cabin experiences.”

The chips are available at the company’s website.

German tier 1 supplier ZF will introduce the next generation of its range extender technology for electric vehicles (EVs), with volume production beginning in 2026.

A range extender combines a combustion-powered generator with an electric motor, producing energy for the vehicle battery once its charge drops.

Dr Otmar Scharrer, Senior Vice President R&D, Electrified Powertrain Technology at ZF, said, "Although the all-electric range of passenger cars is around 500 km on average, range anxiety still influences a wide range of buyers when choosing their next vehicle. These (range extenders) represent a real alternative to larger – and thus more expensive – batteries or plug-in hybrids."

The German supplier has gained experience with range extenders, including supplying systems for the iconic London taxi. Now, it is advancing the technology with two new systems: the electric Range Extender (eRE) and electric Range Extender plus (eRE+).

Both designs are highly integrated and flexible across performance levels, 400V or 800V architectures and semiconductor types. The eRE combines an electric motor, integrated inverter, dedicated software and a planetary gearset. The eRE+ adds an intelligent clutch and differential, enabling it to serve as a generator or a secondary drive. Output is scalable: 70–110 kW for the eRE and 70–150 kW for the eRE+.

Dr Scharrer, added, "The new interest and the increased demand for range extenders shows that the potential of this technology is far from exhausted – in particular for model platforms that are already designed for battery-electric drivelines. Behind our solutions is a system and platform concept. This means that we are optimally equipped to respond to all customer and market requirements with shorter development cycles."

Compared to plug-in hybrids (PHEVs), range extenders offer lower additional costs, faster development, simpler platform integration and easier supply chain management — especially attractive for newer automakers with little combustion engine expertise.

China is currently leading with ‘Range Extended Electric Vehicles’ (REEVs) covering over 700 kilometres, thanks to such technology.

"This is where we find it convenient that there is a wide range of BEV platforms that can be supplemented by range extenders," said Scharrer.

The company is also seeing growing interest in the U.S. and European market.

"The market for all-electric vehicles has not developed as much as predicted a few years ago," Scharrer observed. "For this intermediate phase, range extenders can be the ideal solution."
