Samsung to produce SpaceX Starlink satellite chips at its Austin, Texas fab

Samsung is about to start making some of the brains behind SpaceX’s satellite internet. The company plans to manufacture chips for SpaceX’s Starlink satellites at its semiconductor plant in Austin, Texas.

The chip in question is the STM32V8 microcontroller unit, a small but important component in how Starlink satellites talk to each other in orbit.

What Samsung is actually building

The plan was revealed on November 15, 2026, according to the research findings. Samsung will produce the STM32V8 MCU at its Austin fabrication plant.

In Starlink’s case, the STM32V8 plays a central role in the inter-satellite communications network. Satellites pass data among themselves, and this chip helps make that chatter possible.

The MCU was co-developed with STMicroelectronics, the European chipmaker. Today it is produced at STMicroelectronics’ facility in Crolles, France.

That arrangement is not going away entirely. Production will partially shift to Austin, which means the chip will be built on two continents instead of one.

The chip uses an 18-nanometer fully depleted silicon-on-insulator process, known as FD-SOI.

The money behind the move

Samsung is putting $1.9 billion into expanding the Austin facility. That sits inside a larger commitment of approximately $37 billion across Texas.

Federal money is helping too. Samsung’s Texas plans are backed by up to $4.745 billion in subsidies from the US CHIPS Act, the law designed to lure semiconductor manufacturing back to American soil.

Operational capacity for the new Austin facility is targeted for 2030, according to project details from the NIST and the Commerce Department.

The Austin site will focus on specialty chips for aerospace, defense, and automotive customers. Samsung’s newer facility in Taylor, Texas handles a different job: advanced AI chips for major clients such as Tesla and Nvidia.

Why this is happening now

The move fits Samsung’s strategy to grow its foundry presence in the United States.

The Austin facility sits close to SpaceX’s headquarters, which shortens the physical distance between chip supplier and customer.

What this means for the players involved

For SpaceX, a second production source is a hedge. Relying on a single factory in France for a chip central to Starlink’s communications network is a concentration risk, and Austin spreads that risk out.

For Samsung, this is a credibility play in the foundry business. Winning a marquee aerospace customer gives its US contract manufacturing operation a high-profile reference.

It also helps justify the scale of its Texas spending. A $1.9 billion expansion looks more sensible when there is a named, demanding customer waiting at the other end.

For STMicroelectronics, the arrangement is more nuanced. Production in Crolles continues, but some of the work moves to a partner’s fab in Texas.

For US policymakers, this is close to the ideal outcome the CHIPS Act was built for. Subsidies tied to specialty production for aerospace and defense put strategic components on American soil.
