In fact, the so-called burning is to write code or data inside, which requires specific software and specific hardware, and the data format is generally specific. Chip burning is an important part of the production of electronic products. When burning, you may encounter the problem that the burning speed of some chips is too slow, affecting the production efficiency, which is also an important aspect of customer concern. The burning efficiency is inseparable from the burning speed of the chip. What factors are related to the burning speed of the chip? Let's have a look!

1. Chips from different manufacturers

Differences in chip manufacturers will lead to differences in chip manufacturing processes. The difference in burning efficiency of the same type of chips produced by different manufacturers is due to the differences in chip writing speed caused by the differences in production processes of different manufacturers, which affects the chip burning speed. This will also directly lead to the difference in chip burning speed.

2. The size of the burning program, not the chip size

For the same product, will the burning time of the chip be significantly different with the different chip capacity? The larger the capacity, the greater the burning time of the chip? In chip testing, chips with large capacity do not necessarily burn for a long time. For example, when burning 8MB capacity chips and 16MB capacity chips at the same time, the time is almost the same when burning the same program (the file is less than 8MB).

3. Burning mode of chip

For different brands and types of chips, there are many burning methods. The burning speed of JTAG interface is obviously faster than that of UART interface. For example, some MCU chips provide JTAG interface for burning, but also UART interface for burning. JTAG interface is obviously faster than UART interface. Some SPI flash provide single line burning mode and four line burning mode.

4. Hardware differences of the burner itself

The hardware characteristics of the burner still have an obvious impact on the burning speed of the chip. In the actual test process, the burning time of the same chip will differ by more than half for different burners.

5. Differences in burner channels

The more channels, the more chips can be burned at the same time, and the higher the burning efficiency. The existing burner has a single channel burner with one driven by one and a multi-channel burner with several driven by one. When customers need to burn chips in large quantities, they usually choose multi-channel burner, because this can obviously improve the efficiency. Compare the single channel burner with the eight channel burner. In terms of burning time alone, the service time of the single channel burner is eight times that of the eight channel burner, that is, if you use the eight channel burner, the efficiency will be increased by eight times!

Conclusion: the chip burning speed is affected by the chip itself and the speed of the burner. If you want to burn the chip quickly, please choose the appropriate way and the appropriate burner.
