Chinese smartphone-maker Huawei unveiled another homegrown smartphone chip Friday, while under a U.S. ban that limits its access to American component suppliers.

The Kirin 810 chip will be used in mid-range smartphones from the Nova 5 series, which are priced from 2,799 yuan ($407), Huawei said. The 810 is one of the Kirin series made by Huawei chip unit HiSilicon, based on designs by U.K.-based chip designer Arm Ltd.

Arm told Caixin earlier this week that it was seeking a “swift solution” from U.S. policymakers on its future relationship with Huawei.

The U.S. government placed Huawei on an export blacklist that effectively banned it from doing business with U.S. suppliers like Qualcomm and Google.

In response, HiSilicon’s chief executive said in an internal memo that a contingency chip plan Huawei had been working on for years would be put into use “overnight,” and said that Huawei would maintain “continuous supply of most its products” with the help of HiSilicon. HiSilicon has boasted that some Kirin chips can compete with products from competitors like Qualcomm Inc. and Nvidia Corp.

Huawei said during the Nova 5 launch event that its 2019 smartphone shipments had hit 100 million by the end of May.
