How to detect whether the chip can be burned? Burning method of voice chip

There are many methods of chip burning. In large-scale production, it is still based on burner burning. If you use a burner to burn, you have to use the burning base. The usage times of each burning base can not be effectively monitored. Once the service life of the burning base is exceeded, there is no way to ensure the burning quality of the chip. The burning base does not have the function of detecting whether the burning base matches the chip to be burned, so how to detect whether the chip can be burned?

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.

Let's look at the burning method of voice chip. Voice chip is a part of the chip, voice IC; Chinese is also called sound chip and music chip. It is an integrated circuit chip that can be controlled by keys or MCU. If you need to burn to the chip, you must convert MP3 format to WMV format, and then use the compression algorithm to compress and compile, and then write it to the chip. The memory space of the chip is limited. It is better to use tloff0001 module and call SD card, which will be more convenient You can also add play key, fast forward, pause and other functions.

IC chip burning process requirements and precautions:

1. Be careful when placing the IC to avoid damaging the IC and burning base.

2. The IC must not be installed reversely. The IC with the board removed must first check whether there is a tin short circuit on the pin, otherwise it is easy to damage the burning base.

3. The burning personnel must be trained before taking the post. Other computer programs must not be used during burning.

4. In case of adverse phenomena, immediately feed back to the management personnel for solution.
