Infineon Bets on AI Power Demand With USB Tie-Up, Thai Plant and $1.12 Billion Memory Exit

Infineon partners Taiwan's ASMedia for 20Gbps USB controllers targeting AI data centres, as it sells its memory unit and expands power semiconductor capacity.

Infineon Technologies is sharpening its focus on the hardware that keeps AI data centres fed and connected, unveiling a strategic partnership with Taiwan's ASMedia to deliver USB connectivity at 20 gigabits per second through integrated controllers. The Munich chipmaker said the collaboration targets data-intensive workloads and artificial intelligence systems that depend on rapid signal transmission.

The announcement lands as the company's shares drift sideways. In current trading the stock slipped 0.3% to EUR 63.63, a modest move that contrasts sharply with its performance over the longer haul — a gain of 69% since the start of the year.

A Portfolio Being Redrawn Around Data Centres

The ASMedia deal is the latest in a string of adjustments through which Infineon is repositioning itself within digital infrastructure. Roughly three weeks ago, management agreed to sell its NOR Flash and F-RAM memory business to Winbond Electronics for USD 1.12 billion on a debt- and cash-free basis. That transaction still requires regulatory clearance and is expected to close in the second half of 2027.

At the same time, the group is bolstering its power electronics arm. The team from Indian developer C2i Semiconductors has joined the Power Systems division. Based in Bengaluru, C2i builds software-defined multiphase controllers and smart power stages tailored to the electricity demands of AI servers. No purchase price was disclosed.

Wiring and Power Control Go Hand in Hand

Beyond raw data transmission, Infineon is deepening alliances on energy distribution. It supplies silicon carbide power semiconductors for MVSST 2.0, a platform from US group Eaton. Those solid-state transformers are designed for 800-volt direct-current architectures in Asia-Pacific data centres.

Infineon is also working with SolarEdge Technologies on solid-state power switches for high-voltage grids, and recently introduced its PSOC Control C3 series of microcontrollers for control and motor applications.

The AI boom has turned efficient power conversion into a central battleground for server farms. On an investor call on 1 October, management said AI-related revenue had more than doubled during the current fiscal year, with silicon carbide power semiconductors doing much of the heavy lifting.

Bangkok Fab Ramps as Capacity Builds

To meet that demand, Infineon is expanding its global manufacturing footprint. On 1 October the company opened a new backend plant in Bangkok alongside Thai Prime Minister Anutin Charnvirakul. The facility currently employs around 350 specialists, a headcount set to grow to roughly 1,000 once the first building reaches full capacity.

The C2i acquisition reinforces the same Power Systems division, adding expertise in energy supply for data centres. Analysts have taken note: Jefferies set a price target of EUR 96.00 on the stock on 30 September.

Macro Crosscurrents Swamp Company News

Broader market forces have injected volatility into chip names. Strong quarterly results from US peer Micron Technology initially lifted the entire European semiconductor sector.

At the start of the new trading week, however, chip stocks came under selling pressure again. Market watchers pointed to overarching drags such as rising bond yields, firmer oil prices and inflation worries in the eurozone. No company-specific bad news underpinned the pullback. On Monday the shares fell 1.2% to close at EUR 63.85.

Investors will get a clearer read on how these strategic projects translate into financial results on 10 November 2026, when Infineon reports fourth-quarter and full-year 2026 figures. Underpinning the optimism is a simple expectation: the rewiring of industrial power grids and the build-out of server farms should sustain demand for advanced power semiconductors for years to come.
