Chip online burning, which integrates burning and testing, has attracted more and more attention. In fact, burning is a tool for writing data into programmable integrated circuits. Burning is mainly used to write the program (or brush) of the chip, such as single metal tube (embedded) / memory (embedded). Friends who first came into contact with the embedded system were confused about the concept of programming and burning, and thought that the memory must be burned. In fact, the concept of embedded programming and burning is to write programs into memory, which is similar to downloading in daily life. The burning interfaces provided by the burner are used to cooperate with various encapsulated chips. It is recommended that mass-produced customers choose the adapter recommended by the burner manufacturer for chip burning. If the untested adapter is used, there will be poor contact, chip jamming and other things that will reduce the burning power.

What is chip burning?

Burning is done through a burner or burning card. The English name of the burner is programmer. Some people call it writer. Earlier, some people call it burner. This machine is used to burn a kind of IC called programmable IC. It can burn the cell data inside these ICs, resulting in different functions. Most of the previous ICs were fixed function IC, Therefore, if designers design a circuit board, they must use a variety of different fixed function ICs. For a large number of manufacturers, they need to prepare many types of ICs. Since the emergence of burnable ICs, designers can burn them into ICs with different functions as long as they prepare one IC. The material preparer can only purchase one IC, which is convenient for material preparation, but they must prepare a burner to burn it.

Burning (general) refers to using a recorder to record data (also known as burning) to a recording disc. Such as CD and DVD, the latter has a much larger capacity than the former. Burning is like copy. Copy things in the computer on other file carriers, like a 1.4-inch disk, can be said to be a burning disk. But for example, GBA card is a burn card, but it can't be called a burn card. Burning and recording are the same process, but they are called differently on different carriers. In addition, the recorder has complete functions. Users can delete, check, program, check, encrypt and other common command sequences, and freely organize a single command. It is worth noting that generally speaking, recorders with more chip models are better, which can maximize productivity.

Why do IC chips need to be burned?

First, because there are microcontrollers or arm controllers 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.

Second, you need to 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.

Third, burn files, such as font, pictures, ringtones, animation and so on. 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.

In general, the purpose of IC recording this program is to ensure the normal operation of single chip microcomputer system or ARM chip, as well as the essential documents and parameters in safe operation.

Burnable IC classification

Burning IC is generally divided into MCU class and storage class.

MCU class burnable IC

MCU can burn ic. At present, there are many single-chip controllers (single MCU) in the market that can burn data once or multiple times through the supporting burner. Usually, the MCU that can only be burned once is called OTP MCU. In contrast, MTP MCU is the MCU that can be burned multiple times.

Memory class burnable IC

There are many categories of memory burnable ICs, such as EPROM, EEPROM, nor flash, sprom, NAND flash, etc.

EPROM, nor flash, EEPROM and sprom are mainly used to store our data or programs. There are many manufacturers. There are quite a number of universal burners on the market that can burn data into these ICs. NAND flash is only produced by Samsung and other manufacturers. At present, it is widely used in USB flash disk, MP3, MP4, ELA and electronic dictionary.
