From now on, Russian and Belarusian entities can only buy CPUs operating at below 25 MHz and offering performance of up to 5 GFLOPS from Taiwanese companies. This essentially excludes all modern technology, including microcontrollers for more or less sophisticated devices. 

Due to restrictions imposed on exports to Russia by the United States, United Kingdom, and the European Union, leading Taiwanese companies were among the first to cease working with Russia after the country started full-scale war against Ukraine in late February. This week Taiwan’s Ministry of Economic Affairs (MOEA) formally published its list of high-tech products that are banned from exportation to Russia and Belarus, which prevents all kinds of Taiwan-produced high-tech devices as well as tools used to make chips (whether or not they use technologies originated from the U.S., U.K., or E.U., which were already covered by restrictions) to be exported to the aggressive nation.
