Always do not understand, IC inside the package is thousands of capacitors, resistors, diodes, audion and other components, the internal structure of the same kind of IC is the same, but by burning different procedures into the same kind of IC can achieve different functions. When you burn a program, you just have electrons running around in the IC. What does the program of burning do to IC, what kind of material changes does IC have before and after burning
ic burning machineHow does it work

In fact: not all IC can be burned, only memory can be burned. But now many microcontroller has integrated program memory, so microcontroller can also burn.

There are many MOS tubes inside the memory. The voltage of the gate of MOS tube is difficult to release when charged (the maximum storage is more than 10 years), that is, the voltage of the gate of MOS tube is memory function.

When burning, the program is in the form of binary (0 low level and 1 high level) to charge or discharge the corresponding internal MOS tube grid of the chip to form data preservation. For example, 00000001 data is sent to the memory, and the MOS gate is charged and discharged. In front of 0000000 seven pairs of corresponding MOS tube discharges are stored in a low level form, and the last 1 is stored in the form of charging the MOS tube grid. So the eight MOS tubes store 00000001 of the data.

When reading, the gate discharge output of the MOS tube is O, and the charging output is 1, and a series of data will be read and output.

When the single chip computer works, it first reads the data of the program memory, and then it works completely according to the program data. When to the MCU memory burning different procedures, the MCU work is not the same.

What is the role of ic burning address offset:

1. The mobile phone number used for self-unblocking can be the mobile phone number bound or unbound wechat signal.

2. One mobile phone number can only unlock one wechat signal. (For example, if A phone unblocks wechat A, it cannot unblock wechat B.)

3, self-service lifting restrictions to fill in the wechat bar can fill in the binding mobile phone, QQ, email.

4. You can use domestic or foreign mobile phone numbers for unblocking restriction operation.

5. The validity period of each SMS verification code is 10 minutes.

6. It is recommended to log in 24 hours after the operation is successful.
