Principles of MCU Hardware System Design [Copy link]

The hardware circuit design of a single-chip microcomputer application system includes two parts: one is system expansion, that is, when the functional units inside the single-chip microcomputer, such as ROM , RAM , I/O , timer / counter, interrupt system, etc., cannot meet the requirements of the application system, they must be expanded outside the chip, and appropriate chips must be selected and corresponding circuits designed. The second is system configuration, that is, peripheral devices such as keyboards, displays, printers, A/D , D/A converters, etc. must be configured according to the system function requirements, and appropriate interface circuits must be designed.
