The burning program is to be written on the memory. There is a set of solidified instructions on the chip. After starting, load the specified data and then start running. Similar to the BIOS of the motherboard, the condition to be met is that the chip can read the contents of the memory and has a storage device (which can write data), so that the program can be written according to the function of the chip.

Why burn?

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. When 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. To ensure the normal operation of electronic products.

Third, burn files, such as font, pictures, ringtones, animation and other files. 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 fact, not all ICs can be burned. Only memory can be burned. But now many single-chip computers have integrated program memory, so single-chip computers can also burn. What are the conditions for chip burning? The IC that can be burned 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 many times.

Memory class burnable IC

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

There are many EPROM and sprom manufacturers that can burn data into EPROM or sprom.

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.

The above is the relevant introduction of the conditions for chip burning. If you need this, please consult!
