Why do the decryption chip prices vary widely
Has been engaged in the chip to decrypt the industry, often will hear clients say why chips decryption significant difference in the price above a few hundred pieces, some chips, some chips of thousands of pieces, some chips of tens of thousands of pieces?
What is more, the same chip such as AT89C51 and STC89C51 are 51 single-chip, but decrypt the price difference of nearly 20 times. Why, because the decryption chip prices and our time and pay directly proportional to the this point believe that everyone can understand, spent more time and energy, chip decryption costs are certainly high, decided to chip prices factor The initial investment is what we call technical input to crack a chip initial investment, each crack of a chip, a lot of the hard work of engineers and technical crystallization.
May say that we all feel that there is no convincing example for everyone to see. Or Take AT89C51 and STC89C51 this, why the price will such a big difference, AT89C51 is what film? ATMEL series of 51 single-chip is the microcontroller in the country a few years, all the technical information made public, because many people use the information public high, so decryption is very simple to modify as long as 15 minutes, the circuit about the decryption costs low.
STC89C51 Why so expensive? First, manufacturers are not the same, STC is designed in the United States when manufacturers to design the chip to draw the the AT89C51 easy to crack this feature, intentionally improved his chip encryption mechanism. STC chip space has its own unique place, divided into three parts, the bootloader so 2, the application code, EEPROM, we decrypt the main is for BOOTLOAD District crack, and then read out the program. On this point, the latest version of the STC chip removed the District BOOTLOAD. Above, we need to spend a lot of manpower and resources in order to decrypt the program, and a lot of equipment cost hundreds of millions of tens of millions can only loan, the overall costs to be higher than many, many, so the outside offer is naturally high.
In addition, sometimes even the same model, also there is a big difference in the decryption costs, burn some programs very full and can not even break, especially some of the equipment will be used on a dedicated chip, the difficulty of decryption is very large, the decryption costs will be several times higher than ordinary chips, several times or even a hundred times.
However, with the decryption technology development as well as our in-depth study of the different chip encryption, decryption schemes are constantly optimize, reduce the decryption cost and reduce the decryption prices from all aspects, so that more customers receive the tangible benefits . East guide technology engineers to pursue low-cost and highly accurate crack, has been exploring a better way, false at the time, to let more customers enjoy the benefits brought by the East guide scientific and technological breakthroughs .
