During the 2025 China International Fair for Trade in Services, China Mobile Group's semiconductor and chip design company, China Mobile Core, officially launched the CM6650N, China's first dual-mode narrowband satellite and cellular IoT-NTN chip based on the RISC-V open instruction set architecture, at the Digital Trade Innovation and Development Conference held in Xiongan New Area. The launch of this chip marks a significant advancement in China's satellite communications technology.
The CM6650N chip supports 3GPP Release 17's Non-Terrestrial Network (NTN) 5G standard and boasts several notable features. First, its localization rate exceeds 90%, encompassing the entire supply chain from chip IP, EDA design tools, wafer foundry, to packaging and testing, demonstrating strong independent R&D capabilities. Second, the chip excels in power consumption, with a standby current of less than 1 microampere, making it suitable for extended use.
The CM6650N supports full-band communications, operating from 700MHz to 2.5GHz, enabling dual-mode communication between terrestrial and satellite networks, adapting to a variety of application scenarios. It also supports full-mode communication with both high- and low-orbit satellites, including regenerative payload and transparent forwarding modes.
The product's core advantages lie in its compact design, two-way voice communication capabilities, and global connectivity, driving the widespread adoption of satellite communication technology in high-value sectors such as smartwatches, smartphones, and ocean shipping. China Mobile CoreSheng also offers a complete solution by combining SIM cards, chips, and data plans to help customers implement their businesses. It also provides value-added services through its connectivity management platform to accelerate market adoption. This launch reflects China's breakthroughs in key communications chips, particularly the advancement of its independent design and manufacturing capabilities for RISC-V chips, contributing to the stabilization of the domestic chip supply chain.
