China Mobile NB-IoT communication chip CM6620

CM6620 is China Mobile Xinsheng Technology's first low-power NB-IoT IoT communication chip based on RISC-V core architecture. It uses a domestic 192MHz RISC-V core and 40nm ultra-low power consumption process, combined with a multi-power domain design And optimized clock gating strategy effectively reduces system power consumption. CM6620 has industry-leading sleep power consumption and reception sensitivity. The standby current is as low as 0.9μA and the communication reception sensitivity reaches -118dBm, which can support the normal use of terminals under weak signal coverage. In addition, CM6620 optimizes the protocol stack and software, effectively reducing customer usage costs.
