TSMC has severed its ties with Singapore-based PowerAIR after a client review — triggered by the discovery of a TSMC chip in a 🇨🇳 Huawei AI processor — exposed a potential breach of US export controls.

PowerAIR is the second known company singled out for possible involvement in the Huawei case. TSMC last year suspended shipments to 🇨🇳 chip design firm Sophgo after a chip it ordered from TSMC was found to match one on Huawei’s Ascend 910B multi-chip system.

PowerAIR has no official website and no publicly-listed phone number / email address.
