Socionext developing SoCs for advanced ADAS and AD using 3nm automotive process

1 min read

Socionext is developing custom SoCs for advanced ADAS (Advanced Driver Assistance Systems) and AD (Autonomous Driving) using N3A, TSMC's latest 3nm automotive process technology.

The company said that target production of the SoCs will be in 2026.

TSMC’s 3nm technology enables high volume production while providing for significant improvements in power, performance, and area (PPA) when compared to previous technology nodes. The N3E process offers up to an 18% speed improvement at the same power, or a 32% power reduction at the same speed, with up to a 60% increase in logic density compared to N5.

These PPA improvements are seen as essential for future EV and vehicle deployments, where computing and workload requirements for next generation ADAS and AD applications often compete with the need for longer battery life and driving range.

The SoCs being developed are being designed specifically for advanced driving assistance systems and autonomous driving applications. By combining TSMC’s N3A process technology with Socionext’s knowledge in supporting ISO26262 functional safety product development, AEC-Q100 and IATF-16949 automotive quality and reliability requirements, Socionext said that itwas looking to address the performance and safety demands of the rapidly evolving automotive electronic systems required by Automotive OEMs.

Commenting Hisato Yoshida, Corporate Executive Vice President and the Head of Global Development Group at Socionext, said, “As the advanced ADAS and AD segment continues to grow, our customers are investing in custom SoC solutions to provide product differentiation and optimisation of their hardware compute and software platforms. With customers’ requirements for high levels of integration with multi-core CPU clusters, AI acceleration, image and video processing, high-speed interfaces, as well as security and functional safety support, Socionext’s experience enables our customers to deliver next-generation automotive platforms."

“Socionext has been an early adopter of TSMC’s leading-edge technologies for automotive applications,” said Dr. Cliff Hou, Senior Vice President of Europe and Asia Sales at TSMC. “With our comprehensive automotive technology platform, Socionext will be able to harness the power of 3nm for the computing needed for ADAS and AD without compromising safety and reliability.”

Socionext said that it would start designing with the early release of N3A process known as N3AE, to enable an accelerated schedule to mass production of automotive-grade products.

Through early and close collaboration with TSMC, Socionext aims to be one of the first suppliers of high-performance and energy-efficient automotive products built on the most advanced N3A technology.
