However, even HiSilicon uses ARM technology in its chips. That's because while Huawei does have its own line of Kirin processors, much of the core architecture in those Kirin chips relies on ARM-based designs.
Arm's severing of ties cuts deeper than similar actions from Intel, Qualcomm, Broadcom, Qorvo, Xilinx, Infineon, Micron, and Western Digital, as Arm-licensed designs are used across a number of business units at Huawei, including their server equipment and telecommunications divisions, which utilize Arm-powered processors produced by HiSilicon.
In a statement, ARM said that they are complying with all the regulations and instructions set forth by the US Government, while Huawei does not have anything to say about this matter as of yet. That's because pre-loaded on nearly every late-model Huawei handset is something called the App Gallery, which like Google's Play Store, functions as an alternative way to download apps on Huawei phones.
Yesterday, according to an internal document received by BBC, UK-based chip designer ARM has told its staff that they must suspend business with Huawei.
After a controversial few days, Huawei seems to have gotten another kick in the 'nads as it looks like EE will be pulling the Huawei Mate 20 X 5G from its lineup of 5G handsets, and Vodafone is following suit. "We don't want to do this but we will forced to do that because of the USA government", he told CNBC.
The bans follow an executive order signed by Trump last week, which came in response to us fears that Huawei is effectively an agent of the Chinese government, and that it's equipment could be used to spy on American communications. Huawei is becoming the victim of bullying by the USA administration.

Missouri Governor Mike Parson declared a state of emergency, citing flash flooding, "straight-line winds", heavy rain and hail. The National Weather Service in Tulsa urged people in those areas to move to higher ground, with more rain expected.
"We are confident this regrettable situation can be resolved and our priority remains to continue to deliver world-class technology and products to our customers around the world", it added.
That could, in turn, have a major negative impact on the overall business as Huawei is forced to scramble for alternate technology.
Based on the memo, ARM seems unsure whether it falls under the USA ban, so it's possible Huawei could be granted a reprieve. That is a really tough miracle to pull off - or perhaps Huawei's backup plan foresaw ARM's departure too.
It's a similar situation for Android itself-or at least the version of Android people are familiar with in the United States that comes with Google's wide portfolio of apps and services-which is another thing Huawei may have to abandon if the DOC's tech ban goes into effect.
On the same day, EE confirmed that its range of 5G phones would not include Huawei models.
