Single-chip decryption prices are only very different, some are very cheap, some are very expensive, some chips only need a few hundred dollars, and some need tens of thousands or even hundreds of thousands of dollars, first of all, the price of single-chip decryption and research and development costs are linked, the higher the cost of the program, the higher the corresponding decryption price will be, I believe this point without too much explanation, most people can understand. Therefore, different companies because of different technical strength, the cost of program development is not the same. In addition, the chip on different devices due to different applications, even the same model, there will be a big difference in the cost of decryption, some programs are very full and even can not be cracked, especially some devices will use special chips, decryption is very difficult, so the cost of decryption will be several times higher than ordinary chips, dozens of times or even hundreds of times. Chip technology in the microcontroller decryption can consult under.
