MCU (Microcontroller Unit) is a familiar microcontroller, a single-chip microcomputer that can perform a small amount of simple data operations, consisting of a central processing unit (CPU), flash memory, input/output (I/O), timer/calculator, digital/analog peripherals, and communication interface. 4-bit, 8-bit, 16-bit and 32-bit. As electronic products become intelligent, the high-end demand for automotive, network, industrial control, etc. has led to the mainstream of high-end 32-bit MCU chips.   8-bit and 32-bit MCUs are in competition with each other   From the development trend, the use cases of 4-bit and 16-bit MCU chips are becoming less and less, and 8-bit and 32-bit MCU chips are more active in the market now. In the past, when mechanical control and simple command control were the mainstream, 8-bit MCU single chip had a glorious time and was often used in remote control, power switch, monitor and keyboard, mouse control and other executive work, products such as motor, tool

  A   transistor   is a semiconductor device that switches on and off and amplifies electronic signals. It has at least three terminals that connect it to electronic circuits. The transistor was invented in the early 1950s and quickly replaced vacuum tubes in electronic devices. These devices are now an important part of almost all electronic devices, such as the central processing unit   (CPU)   of computers. A CPU transistor is usually part of an integrated circuit, although it can also be purchased separately.   A central processing unit (CPU). Terminals in CPU transistors have specific names, depending on the type of transistor. The terminals of a simple bipolar transistor are called the collector, emitter, and base. The current or voltage applied to the base affects the flow of current from the collector to the emitter.     The voltage at the base of the transistor can be used to turn on and off the current flowing from the collector to the emitter. This type of transistor is a s
