Introduction

In this engaging episode of The Fully Charged Podcast, host Imogen welcomes Lars Ragers, the Chief Technology Officer of NXP Semiconductors. NXP plays a pivotal role in the automotive industry by designing and manufacturing a significant portion of the semiconductors essential for modern vehicles. This conversation delves into the critical importance of semiconductors in electric vehicles (EVs), the future of automotive technology, supply chain dynamics, and the evolving landscape of AI and edge computing.

Guest Introduction

Imogen introduces Lars Ragers, highlighting his extensive background and the vital role NXP plays in the automotive sector:

"NXP are responsible for designing and manufacturing a huge proportion of the semiconductors used by the automotive industry."

Lars Ragers elaborates on his role and NXP's broad scope:

"[...] 60% of the chips that we are selling is going into cars, industrial robots. So all of that type of electronics for these devices could come from NXP."

Evolution of NXP and the Semiconductor Industry

Lars shares his journey to NXP and the company's transformation during the economic challenges of 2008:

"I thought it was the mistake of my life, but what really happened was that private equity, who was owning us in those days, really looked into each single segment and said, is this fitting to the NXP DNA."

He explains how NXP refocused its portfolio to become an interface, sensing, and smart power company, ultimately leading to profitability and the acquisition of Freescale (formerly Motorola Semiconductors). This strategic pivot positioned NXP as a leader in intelligent systems and robotics.

The Role of Semiconductors in Electric Vehicles

Imogen prompts Lars to define fundamental terms to ensure clarity for listeners unfamiliar with the topic. Lars provides a comprehensive explanation of semiconductors and their necessity in different applications:

"In a normal car, so normal combustion engine car, you have thousand chips, about 1,000. In an electric vehicle, you have up to 10,000 chips."

He emphasizes the complexity and variety of chips required in EVs compared to traditional vehicles, highlighting digital electronics, memory storage, and interfaces to the analog world. This multitude of chips is crucial for functionalities like temperature control, battery management, and autonomous driving features.

Supply Chain and Semiconductor Shortage

The conversation shifts to the challenges faced during the semiconductor shortage exacerbated by the COVID-19 pandemic. Lars discusses the intricacies of the supply chain and the lessons learned:

"If each car that is produced suddenly needs 10 times the amount of chips, then each old architecture that goes out into the market that is replaced by a new architecture is nine times the amount of chips of that old architecture on top."

He underscores the importance of improved communication and collaboration across the supply chain to prevent future shortages. NXP's proactive engagement with OEMs and tier-one suppliers aims to enhance supply resilience and align semiconductor production with evolving automotive architectures.

Innovation and Future of Automotive Semiconductors

Lars elaborates on the future trajectories and innovations within the automotive semiconductor landscape:

"What we are trying to do at the moment is we try to bring these robot architectures into cars."

He outlines the shift from AI-centric models to more robust, multi-layered robot architectures that prioritize safety, security, and energy efficiency. These architectures enable vehicles to perform complex tasks while maintaining reliability and minimal energy consumption, essential for widespread adoption and consumer trust.

Technical Challenges and Opportunities

Addressing the technical aspects, Lars discusses the limitations of Moore's Law in the context of automotive semiconductors:

"Moore's Law is very, very important because you want to bring on a, on a chip of the size of your thumbnail. You don't want to bring 5 billion transistors, you want to have 20 billion transistors to be almighty, to compute more and so on."

He differentiates between high-performance digital chips and the precise, energy-efficient analog chips crucial for automotive applications. NXP is investing in specialized manufacturing processes to cater to these diverse needs, ensuring that chips are optimized for tasks like battery management and sensor data processing without excessive energy consumption.

The Future of AI and Edge Computing

Lars envisions a future where AI systems are embedded at the edge, enabling intelligent, low-power operations within vehicles and other devices:

"If you just, if you google the word semiconductor and then click news, those are the kind of things that you hear about. But actually one of the things that you mentioned earlier about increasing autonomy and connectivity is how you take those analog things that are going on in the world, sense them, and then the robot has to react to them."

He advocates for decentralized AI processing to enhance energy efficiency and data security, reducing reliance on cloud-based systems. This approach aligns with the growing demand for autonomous and connected vehicles that can operate seamlessly and reliably in diverse environments.

Overcoming Industry Challenges

Imogen touches on geopolitical tensions and their impact on the global automotive landscape. Lars acknowledges these challenges but emphasizes NXP's resilience due to its extensive global partnerships:

"If NXP would be irradiated from the globe, I guess most of the cars would not start anymore in the one or the other way."

He highlights the importance of maintaining strong, adaptable relationships with OEMs and tier-one suppliers to navigate geopolitical uncertainties and continue driving innovation.

Conclusion and Final Thoughts

As the discussion wraps up, Lars shares his vision for the future of semiconductors in automotive and beyond:

"If everyone would understand what I'm seeing and would, would, would follow that train of thought, then my job is super easy because I mean, what is the job of a CTO? [...] Create thought leadership. Create thought followership."

He emphasizes the need for collaborative platform development and ecosystem partnerships to advance intelligent system architectures. Lars envisions a future where semiconductors empower a vast network of intelligent, energy-efficient robots and vehicles, transforming industries and everyday life.

Imogen concludes by expressing enthusiasm for the conversation and gratitude towards Lars for his insightful contributions.
