CX310 is a UWB SoC chip positioned in the consumer electronics and Internet of Things market, supports WLCSP and QFN packaging, supports 1T3R, supports centimeter-level positioning, has ultra-low power consumption, ultra-small area and excellent radio frequency indicators. The product performance is leading the world, and will make a great contribution to the development of the entire UWB industry ecology.

Product Overview

The CX310 is a fully integrated single chip impulse radio Ultra Wide Band(UWB) SoC chip with feature of low-power consumption, high integration, high performance, high security, and is compliant to   IEEE802.15.4a HRP, IEEE802.15.4z HRP, FiRa, CCC and ICCE protocols. CX310 supports ranging, AoA (Angle of Arrival), radar and data transmitting. With small packages of WLCSP60  (3.1mm*3.1mm) and QFN40 (5mm*5mm), CX310 is especially suitable for consumer applications, IoT and industry applications.
