Chip testing company: can IC chips be re burned after burning?

With the development of electronic technology, the demand for chips is increasing. In order to improve the production efficiency, multi station IC chip burning technology has been widely used. As a kind of processor, burning chip needs a program to miniaturize all components into one or several integrated circuits; An integrated circuit that can receive coding instructions at one or more ends, execute the instructions and output signals describing its state, and the process of storing programs in the chip is called chip burning.

Can I burn the IC chip again after burning? IC is divided into disposable IC and electrically erasable IC. Disposable IC can only be burned once, but it can be erased by irradiating ultraviolet light after opening the cover, but it has lost its industrial use; The electrically erasable IC can be burned repeatedly.

The purpose of IC burning: because there is a single chip microcomputer or arm controller in electronic products. In the production process, there is no program in the control chip at the beginning. In order for the single chip microcomputer or ARM chip to operate according to the functions designed by us, it is necessary to burn the program execution file written by the project into the controller chip of our electronic products.

Burn the corresponding parameters. After the MCU or arm program is burned, sometimes in order to keep it confidential, it is necessary to set the encryption parameters of the program through serial port or USB and other interfaces, or burn some parameters, such as the IP address and port data of WiFi module. All to ensure the normal operation of electronic products. Burn files, such as font, picture, ringtone, animation, etc. Now many electronic products have display screens. In order to increase the superior user experience for users, it is necessary to ensure that the high-definition photos processed in advance are stored in the single chip microcomputer or arm system. The font file is the bottom file of electronic products called for users to input Chinese characters.

The above is the related content of "IC chip burning" brought by the core creation test. I hope it can be helpful to you. We will bring more wonderful content in the later stage.
