"MCU was born in 1971 and has experienced three stages: SCM, MCU and SOC. Single chip microcomputer has developed from 1-bit, 4-bit, 8-bit and 16-bit to 32-bit or even 64 bit.
After the 1990s, with the great development of consumer electronic products, single chip microcomputer technology has been greatly improved, and a number of single chip microcomputer manufacturers have been born one after another. Let's take a look at the original MCU chip factory and its products:
