Press Release

Socionext Begins Development of SoCs for Advanced ADAS andAD Using 3nm Automotive Process[Yokohama/Japan. October 23, 2023] --- Socionext Inc., today announced it is developing custom SoCs foradvanced ADAS (Advanced Driver Assistance Systems) and AD (Autonomous Driving) using N3A, TSMC's latest
3nm automotive process technology. Target production of the SoCs will be in 2026.
TSMCʼs 3nm technology enables high volume production with significant improvements in power, performance,and area (PPA) when compared to previous technology nodes. TSMCʼs N3E process offers up to 18% speed
improvement at the same power, or 32% power reduction at the same speed, with up to 60% increase in logic
density compared to N5. These PPA improvements are a key ingredient 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 designed specifically for advanced driving assistance systems and autonomous
driving applications, achieving exceptional performance and low-power consumption. By combining TSMCʼs N3A
process technology with Socionextʼs experience to support ISO26262 functional safety product development,
AEC-Q100 and IATF-16949 automotive quality and reliability requirements, Socionext is addressing theperformance and safety demands of the rapidly evolving automotive electronic systems required by AutomotiveOEMs.
"We are excited to announce that we are continuing our history of adopting TSMC's leading-edge process
technologies for automotive chip development" said Hisato Yoshida, Corporate Executive Vice President and theHead of Global Development Group at Socionext. “As the advanced ADAS and AD segment continues to grow,our customers are investing in custom SoC solutions to provide product differentiation and optimization of theirhardware compute and software platforms. With customersʼ requirements for high levels of integration withmulti-core CPU clusters, AI acceleration, image and video processing, high-speed interfaces, as well as security
and functional safety support, Socionextʼs experience enables our customers to deliver next-generation
automotive platforms. TSMC is a key silicon manufacturing partner for Socionext, not only for automotive
developments, but for a wide range of applications ranging from consumer and industrial to datacenter andnetworking"“Socionext has been an early adopter of TSMCʼs leading-edge technologies for automotive applications,” said Dr.
Cliff Hou, Senior Vice President of Europe and Asia Sales at TSMC. “With our comprehensive automotivetechnology platform, Socionext can quickly harness the power of 3nm for the computing needed for ADAS andAD without compromising safety and reliability, and we are excited to see the innovations they will bring to life”
Socionext will 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.
