AT91SAM 100% unlock success.
The conditions for IC unlock are:
First, you have some knowledge and know-how to turn an encrypted chip into no encryption.
Second, there must be a tool for reading the program. Some people may say that it is nothing more than a programmer. Yes, it is a programmer, but not all programs have the ability to read. That’s why we sometimes develop a readable programmer to crack IC.
What is chip decryption?
Many people are interested in IC to unlock technology; how is the IC crack? Is there a sort of decryption device the chip can directly unlock when putting on it? Because there are often customers who consult this aspect of the problem, it is necessary to introduce the crack device and the decryptor briefly. There are many types of chips. Currently, chip decryption refers to chips with memory in the chip, such as MCU microcomputer, DSP, ARM, CPLD, etc. Since these chips encrypt after burning the user program, the usual means cannot read. T, the chip needs to decrypt.
Chip unlock equipment:
There are many tools for decrypting devices:
For example, we often hear about FIB equipment. FIB is not a IC unlock device. FIB is a focused ion beam device. It is an instrument for cutting and connecting materials at the nanometer level. Of course, it is the most widely used in the field of microelectronics. FIB decryption chip, then it is necessary to modify the chip circuit, so that the encrypted chip becomes a non-encrypted chip, as a chip circuit, is very complicated, how to change, modify what, this is a technical problem. For example, Beijing Zhixin Technology has its FIB equipment specializing in the decryption of chip circuits and has rich experience.
Also, the equipment that often uses is a microprobe, not only in the decryption of the chip but also in any microelectronics test and experiment; the microprobe is inseparable right probe station has perfect decryption of the chip. Great help.
