Chipsea Technologies' ASIL-D functional safety MCU K7 series empowers smart vehicles and physical AI

On October 27, during the concurrent events of the Shenzhen International Semiconductor and Electronic Components Exhibition (ES SHOW), the Second Domestic Chip Technology Innovation and Market Application Forum was grandly held at the Shenzhen World Exhibition & Convention Center. Xu Yudong, General Manager of the Automotive Electronics BU at Chipsea Technology (stock code: 688595), was invited to attend and delivered a keynote speech titled "From Precise Perception to Safe Execution: Chipsea Functional Safety MCU Solutions Empower Physical AI," sharing the latest progress of Chipsea's automotive-grade chips in physical AI edge deployment.

Computing Power Determines the Ceiling; the Edge Holds the Safety Bottom Line

In this regard, Xu Yudong judged: as large models and computing power reshape intelligent vehicles, "big chips" such as large models and high-level intelligent driving determine the experience ceiling, while edge "small chips" such as functional safety MCUs hold the safety bottom line of physical execution. Computing power is responsible for "thinking," while the safety of physical execution such as braking, steering, and power cutoff must be "acted upon" by automotive-grade MCUs. Centralized computing and distributed intelligence will coexist for a long time; the more centralized the architecture, the higher the density of edge safety chips.

"Chipsea's automotive electronics business mainline has always revolved around: from 'precise perception' to 'safe control,' building full-signal-chain automotive-grade chip solutions," Xu Yudong stated. What Chipsea provides is not a single-chip capability, but system-level solutions for scenarios such as intelligent driving and physical AI, providing a safety bottom line for customers and the overall vehicle experience. As "physical AI on wheels," automobiles impose incompressible requirements on real-time control, fail-safe response, and functional safety, and this will certainly be the main battlefield of Chipsea's automotive electronics.

In this regard, Xu Yudong focused on introducing the ASIL-D functional safety MCU K7 series and its platform-based development path for multiple scenarios.

Currently, the domestic localization rate of ASIL-D MCUs, the highest functional safety level, for powertrain, chassis domains, and other areas is less than 5%. Chipsea's K7 series benchmarks against international leaders, translating the four major capabilities of "safety, connectivity, control, and intelligence" into value perceivable by the whole vehicle. For example, for 48V electrical architectures, the K7 series optimizes for power consumption and reliability challenges, translating technical benefits into vehicle energy consumption, range, and driving experience; in key scenarios such as chassis braking, battery management, and domain control, the chips feature built-in fault monitoring and information security protection and adapt to a rich set of automotive interfaces, enabling the system to respond safely and operate reliably even under abnormalities, holding the vehicle safety bottom line for customers.

Full-Signal-Chain Perception: Guarding the First Gate of Safety Perception

Beyond functional safety MCUs, Chipsea's automotive-grade analog/signal-chain chips are equally "everywhere."

Products such as high-precision ADCs, BMS AFEs, power fast charging, and ASICs undertake the precise acquisition of weak physical quantities such as voltage, current, and temperature, serving as the first perception gate for safe execution. Many have passed AEC-Q100 certification and entered mass production, applied in scenarios such as smart cockpits, in-vehicle fast charging, and battery management.

Specifically, the 16-channel low-power high-speed SAR ADC CS17953 has been mass-produced and applied to BMS sampling for a leading domestic commercial vehicle company; the BMS AFE CBM9680 has obtained ISO 26262 ASIL-B certification and is applied to start-stop battery products of a leading international battery company; the automotive-grade USB PD control MCU CS32G020Q has been mass-produced and applied to the passenger vehicle platform of a leading international automaker; the light and rain sensor AFE CAF1295 and powertrain/chassis ASICs are also continuously being deployed in corresponding scenarios. High-precision detection and safety control work in concert, forming the foundation of Chipsea's full-signal-chain solutions.

The barrier of automotive-grade chips lies not in a single product but in the system. Chipsea has obtained TÜV Rheinland ISO 26262 ASIL-D certification, passed the international Tier 1 VDA 6.3 factory audit, had the MCAL software of its automotive-grade functional safety MCUs pass ASPICE L2 certification, and is promoting the construction of the GTM Trace open-source alliance, making its self-developed specifications freely open. Xu Yudong emphasized that Chipsea's cooperation with customers is not limited to product portfolios but is a multi-layered binding of product portfolios, strategy, goals, capacity, quality, and systems—mutual recognition and systematic alignment in quality processes.

Loyal to Automobiles, But Not Limited to Automobiles

From precise perception to safe control is the "last mile" of physical AI deployment. Intelligent vehicles and humanoid robots share the same architecture and supply chain origins, sharing underlying technologies of perception, control, drive, power supply, and connectivity. Chipsea is striving to extend its automotive electronics technology accumulation to physical AI scenarios such as embodied intelligence, energy storage, industrial automation, and drones.

Loyal to automobiles, but not limited to automobiles. Chipsea Technology will continue to solidify its dual technology platforms of "analog + MCU," working with automakers, Tier 1 suppliers, and ecosystem partners to build domestic automotive-grade chip solutions, promoting the large-scale deployment of physical AI in intelligent vehicles and edge hardware, and writing safety into every chip.
