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

In the process of purchasing electronic components, the most worrying thing for buyers is not the price, but the quality of the product. There are a variety of IC chips on the market, of all kinds, and without paying attention to the distinction, it is sometimes difficult to see the difference between various materials, whether it is true or false, new or refurbished. The following is a compilation of some methods to identify genuine and fake chips, for your reference. Common chip counterfeiting methods Material A counterfeit material A Original manufacturer's tailor loose material: the original packaging has been disassembled or is no longer available, but product functionality and yield may be lower due to storage time or handling process, etc. Original manufacturer scrap or defective products: mainly products that have not passed factory inspection by the original manufacturer, such as scrap products after reliability testing, poor packaging quality, bad test products, etc. Orig
