Nanjing Qinheng Microelectronics CH570, a 10 cent 32 bit Chinese microcontroller, RISC-V core, 12 Kbytes of SRAM and 240 Kbytes of EEPROM, with many fancy IO trimmings. With Trump tariffs, maybe 20 cents. Unless we anger the Chinese, and they choose not to sell to a noisy former superpower with only 4% of the world's population.
