Chinese computer chip firm Changsha Chixin Semiconductor Technology Co., Ltd. announced on Wednesday that it will launch its first commercial ultra-wideband (UWB) chip: the CX300. According to the company, this product can be applied to industries including smartphones, automobiles and the Internet of Things.
The CX300 supports the latest IEEE 802.15. 4z standard, featuring low power mode and supporting multi-antenna solutions, as well as FiRa Consortium and Car Connectivity Consortium (CCC) specifications.
In terms of performance, the positioning accuracy can reach 5cm at sight distance, and the angle measurement accuracy can reach plus or minus three. Its various features, performance and power consumption indexes can meet the needs of different application scenarios such as smart home appliances control, digital keys and indoor positioning.
The UWB technology was first applied by Apple’s iPhone 11 series in 2019, which can be used for short-distance high-precision positioning. At present, iPhones, Samsung’s flagship models and Xiaomi‘s MIX 4 smartphone have all supported UWB, and China has listed this technology as an important part of the new national 5G infrastructure.
Chixin Semiconductor said that with the support of industrial partners, this chip has a stable and large-scale supply capacity, which helps domestic UWB chip customers to provide guarantees in application.
According to its official website, Chixin Semiconductor Technology was established in 2020 with a registered capital of 21.92 million yuan ($3.44 million). It is headquartered in Xincheng Science & Technology Park, Changsha High-Tech Industrial Development Zone, and has set up a Shanghai branch. The company focuses on the R&D and sales of UWB chips, and its core technologies are all self developed including architecture, baseband, algorithm, RF and protocols.
