A Canadian research firm called TechInsights took a deep dive on one of Huawei’s artificial intelligence accelerators and found a chip manufactured by Taiwan Semiconductor Manufacturing Company (TSMC). Bloomberg spoke with several people familiar with the investigation who asked to remain anonymous since TechInsights’ report has been released to the public.

The anonymous sources says TechInsights’ investigation found an Ascend 910B chip made by TSMC in one of Huawei’s AI accelerators. The company that conducted the investigation declined to comment.

The US Commerce Department implemented additional trade restrictions against Huawei that barred the electronics company from obtaining chips made by foreign firms. Earlier this year, the US government tightened its restrictions even further by revoking its licenses with Intel and Qualcomm to produce chips for its devices.

TSMC denied that it had a working relationship with Huawei since mid-September of 2020 in a statement provided to the Commerce Department. TSMC also told Bloomberg that it hasn’t produced any chips for Huawei due to the amended restrictions. Huawei denied that it had ever “launched the 910B chip.”

This isn’t the first time Huawei has been caught trying to subvert US sanctions and trade restrictions. Bloomberg also uncovered in May that Huawei funded secret research in the US at universities including Harvard by funneling the money through a Washington-based scientific research foundation called Optica. The foundation said it decided to return the money in June and chief executive officers Elizabeth Rogen and Chad Stark stepped down the following August.
