Samsung Electronicsa world leader in advanced semiconductor technology, and Ambarella, Inc. (NASDAQ: AMBA), a leading AI semiconductor company, today announced that Samsung’s Foundry business is providing its 5 nanometer (nm) process technology to Ambarella for its Newly Announced CV3-AD685 automotive AI central domain controller. This collaboration will help transform the next generation of self-driving vehicle safety systems by bringing new levels of AI processing performance, power and reliability.

The CV3-AD685 is the first production version of Ambarella’s CV3-AD family of automotive AI central domain controllers, with Tier 1 automotive vendors announcing that they will offer solutions using the system product family on chip (SoC) CV3-AD. Samsung’s 5nm process technology is optimized for automotive-grade semiconductors with extremely tight process controls and advanced IP for exceptional reliability and outstanding traceability.

Ambarella will build on Samsung’s 5nm process maturity and strong technology track record. This 5nm process leverages the company’s extensive experience in automotive foundry processes, intellectual property and service package development to enable manufacturers to create cutting-edge innovations in assisted and automated mobility.

“Ambarella and Samsung Foundry have a rich history of collaboration, and we are excited to bring their world-class 5nm technology to our new CV3-AD685 SoCs,” said Fermi Wang, Chairman and CEO of Ambarella. “Samsung’s proven automotive process technology allows us to bring new levels of AI acceleration, system integration and energy efficiency to ADAS and L2+ to L4 autonomous vehicles.”

The CV3-AD685 incorporates Ambarella’s next-generation CVflow® AI Engine, which includes 20x faster neural network processing than previous generation Ambarella CV2 SoCs. It also provides general vector and neural vector processing capabilities to deliver the overall performance required for fully autonomous driving (AD) stack processing, including computer vision, 4D imaging radar, sensor fusion depths and trajectory planning.

“Samsung is bringing 5nm FinFET EUV technology to automotive applications for unprecedented ADAS and vision processor performance,” said Sang-Pil Sim, Executive Vice President and Head of Foundry Business Planning at Samsung Electronics. “With Tier 1 automotive suppliers already adopting the technology, we believe other automakers will also consider using the Ambarella CV3-AD family of SoC products manufactured using Samsung’s 5nm process.”

The CV3-AD685 will be the first in the CV3-AD product family to use Samsung’s 5nm process, and this SoC incorporates advanced image processing, dense optical and stereo stream engine, ARM® Cortex® A78AE and R52 processors, an automotive GPU for visualizations and a hardware security module (HSM). It features an “algorithm-first” architecture that supports the entire autonomous driving software stack.

The high-performance, energy-efficient and scalable CV3-AD family, purpose-built for ADAS, complements a wide range of solutions for assisted driving while advancing vehicle automation. The integrated SoC CV3-AD685 enables the fusion of information from various sensors for robust autonomous driving from L2+ to L4. Samsung Foundry’s advanced processing technology and advanced 3D packaging solutions power many of the latest mobile, HPC and automotive solutions.

Samsung’s 5nm process is also supported by the Samsung Advanced Foundry Ecosystem (SAFE™) program. The SAFE™ program ensures close collaboration between Samsung Foundry, ecosystem partners and customers to deliver robust SoC designs based on certified key design components including process design kits (PDKs), workflows reference with design methodologies (DM), a variety of intellectual property (IP), and on-demand design support.
