Advancing Space Microelectronics
The European Space Agency (ESA) is launching the Ultra Deep Submicron Initiative, focusing on the advancement of microelectronics for space applications. This initiative is crucial as European space missions require increasingly powerful microprocessors, necessitating a reduction in chip sizes from the current 65 nm down to 7 nm. The reduction not only enhances functionality but also potentially leads to cost reductions and improved performance in space operations.
According to Boris Glass, ESA’s microelectronics engineer leading the initiative, the performance of space missions hinges on their underlying microelectronics technology. In terrestrial applications, advancements have followed Moore’s Law, which states that microprocessor performance doubles approximately every 18 to 24 months. However, the space sector operates under specialized requirements that often necessitate modifications to standard consumer electronics chips, which are not suitable for the rigors of space due to their exposure to radiation and other harsh conditions.
The LEON5 integrated circuit, currently in use for space applications, exemplifies existing limitations, underscoring the need for the Ultra Deep Submicron Initiative. Boris Glass notes that the space sector has lagged approximately seven years behind the cutting-edge microelectronics technology typically found in smartphones and computers. This initiative aims to close that gap by creating more powerful and agile microprocessors capable of meeting the demands of future space missions.
One of the primary challenges faced by microprocessors in space is radiation damage, which can cause random bit flips in memory or even catastrophic failures like latch-ups. To counter these effects, the design of new microprocessors includes protective measures such as redundancy and error detection systems, ensuring that single-bit errors do not compromise system integrity. These innovations will be essential building blocks as designers create new integrated circuits under the initiative.
Frontgrade Gaisler, a Swedish company with nearly 25 years of experience in space-grade microprocessor technology, is at the forefront of the initiative. Sandi Habinc, General Manager at Frontgrade, emphasizes the team’s initial focus on establishing a reliable library of radiation-hardened designs that can be leveraged for future advanced products, including high-performance microprocessors.
While collaborating with external foundries for the initial stages, the long-term goal is to develop advanced manufacturing capabilities within Europe. This aligns with efforts to reduce reliance on foreign suppliers and strengthens the European supply chain for space-ready integrated circuits. The initiative is part of the broader ‘EEE Space Components Sovereignty for Europe’ program backed by the European Union’s European Chips Act, aimed at fostering innovation and independence in the field of electronics.
Overall, the Ultra Deep Submicron Initiative represents a pivotal step towards enhancing Europe’s capabilities in space technology. By focusing on the development of advanced microelectronics, ESA aims to secure the technology needed for future space exploration endeavors, including satellite constellations and the incorporation of advanced artificial intelligence and edge computing in space operations. This initiative not only supports immediate technological advancements but also aims to ensure Europe retains a competitive edge in the global space sector.
