The core chips used in many rockets are still based on 130nm or more mature processes.
Astronaut-grade chips, used in rockets, etc., the requirements are more different, the more complex and advanced chips, the easier it is to break, the simpler and more durable, and the most important thing for astronaut-grade chips is to prevent radiation, and work normally at the limit temperature, after all, the radiation in space is very serious, and the temperature difference is particularly large.
