With a single RISC-V core running at 120 MHz, the new SIM offers 10 times the data transfer speed of a standard SIM and about 2 times faster than current high-end super SIMs already in use in the IoT. The RISC-V SIM card’s 2.5 MB of built-in flash memory is also 10 times the capacity of a standard SIM card and twice as much as other super SIM cards.
Examples of how China Mobile’s super SIM card can be used include electronic student IDs, digital car keys, public transportation and other access control applications.
However, future innovations on a chip may not see the light of day. The fact is that the US government is trying to block China’s access to the RISC-V protocol.
