According to microcontroller developers, the PIC8 bit microcontroller is a dual inline plastic package with a clock frequency of up to 4Mhz. As a consensus private technology, the technical specifications of this product can be found online. However, although PIC8-bit microcontrollers are not large, they still require a complete computer with a processor, program memory, data registers, and input/output ports, all of which are indispensable.

Like other microcontrollers, the CPU of PIC8 bit microcontrollers is also its leader, and when the chip reads and executes instructions from memory, it will call the data. In PIC8-bit microcontrollers, general-purpose data RAM is also considered a register. Of course, in addition to ordinary data registers, there are also some extra existence, and these working registers that are considered exclusive registers are called W registers. The CPU of a PIC8 bit microcontroller places it in this register and controls the operation of the PIC8 bit microcontroller in some way, along with other registers.

Microcontroller developers also pointed out that the program memory of PIC8-bit microcontrollers is mainly composed of FlashEPROM, which can be used for recording and erasing, and can still retain content even when power is off. Some models of program memory only use EPROM, which is usually erased with ultraviolet light. In addition, some disposable programmable products cannot be erased.

The PIC8-bit microcontroller has two output and input ports, each of which can be set as a separate output and input port. Therefore, it can still save content in case of power failure, avoiding the loss of important content. However, microcontroller developers emphasize the need to pay attention to certain functions of the microcontroller, otherwise programming errors may occur.
