SiliconAuto Unveils Automotive MCU at Hon Hai Tech Day

Driving a New Revolution in Automotive-Grade Semiconductors

Taipei, TAIWAN – At this year’s Hon Hai Tech Day, the premier technology exhibition hosted by global electronics leader Hon Hai Technology Group (Foxconn), SiliconAuto officially unveiled its debut product, a 32-bit microcontroller unit (MCU), verified as ISO 26262 ASIL-B Product Ready, ensuring compliance with automotive functional safety standards. Fabricated using TSMC’s advanced 28 nm process technology, the MCU integrates a 160 MHz Cortex-M33 processor, 1MB embedded flash, 128KB SRAM, and versatile I/O, designed for a wide range of automotive applications.

Hon Hai Tech Day has rapidly become one of the most prominent platforms for emerging technologies within Foxconn’s innovation ecosystem, drawing thousands of global industry leaders, innovators, and media to Taipei each year. The event spotlights breakthroughs across smart manufacturing, electric vehicles, AI, and robotics. For SiliconAuto, launching its debut product at this influential venue underscores its alignment with Foxconn’s vision and positions it at the forefront of silicon development in the age of AI and autonomy.

At its stand, SiliconAuto showcased its new MCU controlling an adaptive front lighting system. The demo integrated the MCU with LED Matrix technology and a SiliconAuto hardware-software reference platform. Featuring flexible interfaces, smart lighting control, and functional safety support, this turnkey solution helps automakers scale adaptive driving beam (ADB) headlights from luxury models to mainstream vehicles. It gives customers a solid foundation to develop ADB solutions efficiently, without the complexity of starting from scratch.

Alongside the ADB demo, SiliconAuto previewed future MCU family extensions with the help of digital twin technology. This approach allows software development to start before chip tape-out, enabling customers to collaborate on virtual proof-of-concept and accelerate architecture exploration. Beyond automotive, the demo highlighted how zero-defect, fine-control, and low-latency capabilities extend to fields such as robotic arms and drone controls; a cost-effective way to customize next-generation silicon.

SiliconAuto is setting a new benchmark in the automotive-grade semiconductor market, transforming how automakers approach intelligent systems. Through its MCU, SiliconAuto demonstrates the expertise required to design next-generation silicon with automotive-grade safety and security, extending to future high-performance computing system-on-chip (SoC) products.
