PIC IC unlock
PIC series MCU of MICROCHIP Company widely use in the world at present.
From High-difficulty IC unlock series:PIC18k,pic18j crack,pic18f break,pic16f mcu crack,pic12f,pic10f unlock, PIC MCU can divide into the following two categories:
Previous stage: the difficulty of decryption is very low.”
General PIC MCU
Current: Nearly impossible to decrypt
New PIC MCU
It can see that even as the world’s MICROCHIP company with active research and development ability of MCU, the development of its MCU encryption technology is also torturous.
As we all know, the previous “ordinary PIC MCU” can easily unlock by using a straightforward ultraviolet erasure method, which made many engineers abandon PIC MCU and seek other chips with better encryption performance.
(For example, ST7 series MCU.
As a result of the previous experience, MICROCHIP has adopted a very advanced manufacturing technology in the “new PIC MCU,” and its encryption circuit completely abandons the traditional encryption principle, which makes much real chip decryption technology have no way to it.
It can say that from the complexity of the encryption circuit; the new PIC MCU is even more difficult to decrypt than the highly integrated ARM chip and DSP chip, which was almost unimaginable in the past.
Because of this, although the “new PIC series MCU” has been available for a long time, it can still not unlock after several years. In addition to MICROCHIP,
There are not many MCU in the world that can do this.
With the emergence of “new PIC MCU,” given its excellent encryption performance, more and more development engineers begin to use PIC MCU again. At the same time, due to the excellent compatibility of PIC MCU, many engineers also transplant the original program into “new PIC MCU.” With such a simple change, the encryption performance of the product will greatly improve immediately! (e.g.
PIC16F73 can be upgraded to PIC16F723, PIC16F913 to PIC16F1933, PIC18F2580 to PIC18F25K80, etc.
It can say that for the new PIC MCU, there are probably one or two companies in China that can do a little research on the encryption principle of such chips without discussing how to unlock them.
The following table shows some models of the new PIC MCU.
