Socionext Adopts TSMC’s 5-nanometer Technology for Custom SoCs Targeting Next-Generation Automotive Applications

Delivering World-Leading Performance and Automotive Quality with Flexibility of Custom Design

Langen/Germany, 4. February, 2021 --- Socionext Inc., a world-leading provider of custom System-on-Chip (SoC) solutions, today announced that it will adopt TSMC’s latest 5-nanometer process technology (N5P) for Socionext’s high-performance SoC development for next-generation automotive applications. The custom SoC solutions target high-level advanced driver assistance systems (ADAS) and autonomous driving (AD) vehicles and are slated for risk production in 2022.

TSMC’s N5P, a member of its 5-nanometer family, is the world’s most advanced process technology available in the market. As capacity continues to ramp, N5P’s defect density reduction is proceeding faster than that of the previous generation. N5P is an enhanced version over N5, providing a 20% performance gain or a 40% power reduction, and up to 80% logic density gain over the preceding N7 technology. At the same time, N5P enjoys support from the industry’s most comprehensive design ecosystem.

“We are delighted to adopt TSMC’s world-leading N5P technology for our next-generation automotive development platform,” said Noriaki Kubo, Corporate Executive Vice President and the Head of Automotive & Industrial Business Group at Socionext. “The ADAS/AD segment requires extremely high arithmetic processing, and Socionext will contribute to customers’ next-generation automotive development by utilizing this advanced process technology from TSMC, our important partner in a wide range of products from consumer to automotive products.”

“Innovative semiconductor technology is essential for accelerating the development of next-generation smart automobiles,” said Dr. Cliff Hou, Senior Vice President of Europe and Asia Sales and Corporate Research at TSMC. “The collaboration with Socionext demonstrates our commitment to offering world-leading semiconductor technologies to achieve maximum value for customers’ products.”
