STMicroelectronics has unveiled its new Teseo VI series of global navigation satellite system (GNSS) receivers, designed to provide accurate positioning solutions for a wide range of industries. These receivers will play a key role in automotive systems, including advanced driving assistance systems (ADAS), smart in-vehicle systems, and autonomous driving. They are also suited for industrial applications such as asset tracking, mobile robotics, machinery management, crop monitoring in agriculture, and timing systems like base stations.
Luca Celant, General Manager of Digital Audio and Signal Solutions at STMicroelectronics, emphasized the breakthroughs introduced by the Teseo VI series: “These receivers are the first to integrate multi-constellation and quad-band signal processing into a single chip, using a dual-Arm®-core architecture to ensure high performance and safety for both assisted and autonomous driving. They also feature ST’s proprietary embedded Non-Volatile Memory (PCM), creating a highly integrated, cost-effective platform for precise positioning.”
The Teseo VI series is the first to combine all system elements required for centimeter-level positioning accuracy into one chip. It supports multi-constellation and quad-band operations simultaneously, simplifying the development of navigation products, improving reliability in challenging environments like urban canyons, and reducing material costs. It also shortens time-to-market and enables more compact designs.
STMicroelectronics brings its extensive experience to the Teseo VI series, integrating advanced positioning and embedded memory technologies. The receivers include the Teseo VI STA8600A and Teseo VI+ STA8610A, both featuring dual independent Arm® Cortex®-M7 processing cores for managing integrated circuit functions. These cores offer powerful 32-bit processing and enable simultaneous multi-constellation and multi-band operations on a single chip.
Teseo VI+ receivers can also work with additional positioning engines developed by third-party partners, allowing for centimeter-level accuracy using real-time kinematics. Another version, the Teseo APP2 STA9200MA, features dual cores operating in lockstep, providing redundancy for high-safety applications like vehicle guidance systems meeting ISO 26262 ASIL-B functional safety standards. The pin compatibility of all Teseo VI ICs simplifies PCB design for both ASIL-certified and non-ASIL applications.
Each version of the Teseo VI receivers includes ST’s innovative RF architecture and GNSS baseband design. The receivers support quad-band GNSS (L1, L2, L5, and E6), with the ability to track only the L5 band. This improves signal robustness and reduces data errors in challenging environments such as urban areas or areas with jammers.
Additionally, STMicroelectronics’ phase-change memory (PCM) technology eliminates the need for external memory, reducing material costs and simplifying the supply chain. PCM is durable, able to withstand tough conditions like those found in automotive environments, and offers non-volatile memory similar to Flash but with smaller cell sizes for more efficient on-chip integration.
The devices are equipped with security features such as secure boot, over-the-air firmware updates, and output data protection. They also include a hardware security module (HSM) to guard against cyber threats and meet cybersecurity standards like UNECE R155 and ISO 21434.
STMicroelectronics supports the Teseo VI series with a network of suppliers and partners who provide algorithms, reference designs, and complementary hardware. For automotive applications, two new GNSS modules, the Teseo-VIC6A and Teseo-ELE6A, integrate the Teseo VI and Teseo VI+ ICs, respectively. These modules, available in compact form factors, simplify integration and deliver optimal performance.
As a leader in semiconductor technologies, STMicroelectronics is dedicated to creating innovative products that enhance mobility, energy efficiency, and the deployment of cloud-connected autonomous systems. The company is committed to achieving carbon neutrality by 2027, including some indirect emissions.
