AVR Series MCU unlock /crack:
From encryption technology, the existing AVR MCU can roughly divide into “ordinary AVR MCU” and new AVR MCU (such as ATMEGA88PA, ATMEGA406, and ATMEEGA644).
At present, ordinary AVR MCU has been very easy to crack, while the new AVR MCU, because of the use of ATMEL company’s more modern encryption technology, makes its chip unlock significantly more difficult.
However, because AVR MCU generally adopts a relatively backward manufacturing process of 0.35um aluminum, and the layout module of its encryption circuit is less updated, this makes the AVR MCU unlock difficulty compared with the new PIC MCU and ST7 series MCU still has a big gap.
Of course, even so, there are only a few companies in China that can decrypt the new AVR MCU.
So how to judge which company can unlock your new AVR MCU?
The answer is simple. You need to follow the two principles.
1, the cycle principle: if a company can decipher the new AVR MCU, its IC unlock cycle will inevitably be within one to two days.
2. Compensation Principle: If a company can unlock the new AVR MCU, it must be willing to sign the “unlock Failure Compensation Agreement” with customers.
If a company claims to be able to crack the new AVR MCU, but flickers in the unlock cycle, and is more reluctant to sign the corresponding compensation agreement, then it can be determined that it can not decrypt the new AVR MCU at all, but just want to deceive customers by delaying time all or part of the deposit. Such cases have long been common in the IC unlock industry.
The encryption characteristics of AVR MCU, in addition to the above content, now some AVR MCU also uses “RC calibration software encryption,” which is also one of the highlights of AVR chip encryption technology.
Also, MEGA406 chips, which widely used in the management of notebook batteries, also contain a variety of sophisticated software encryption methods including ID code encryption, which makes the unlock challenging to reach an unprecedented height.
