Since its establishment in 2005, SZ OROD has set up its IC crack and microcontroller software development team. In 2002, the IC crack department was formally established (all decryption services are restricted to legal channels, and the master film provider is responsible for the software copyright. Our company does not undertake any legal responsibility!). After continuous exploration and research, our company can crack more than 30 ICs, more than 2,000 models and develop 51 series, PIC series, ELAN series single-chip software. Our company also acts as a sales agent for several domestic and foreign programmers, emulators, IC test sockets, and programming adapters. It undertakes IC bulk OEM programming services for the convenience of customers.

Following the successful breakthrough of Japanese high-level decryption chips such as Mitsubishi, Renesas, Hitachi, etc., recently, to meet the specific decryption needs of our customers, our company’s professional decryption engineers have also formed an NEC series microcontroller crack solution development team, explicitly unlocking NEC series chips. Scheme development.

We know that in the IC crack industry, Japanese chips are a typical type of complex IC, such as Hitachi, Mitsubishi, Toshiba, and other Japanese chip design manufacturers; the MCU encryption technology is very mature, its MCU encryption performance is excellent, the crack is complex, and the application More and more widely, on the one hand, it has become the first choice of many product designers, on the other hand, it has become a significant problem for many reverse engineers.

 As a representative of Japanese chips, the NEC series MCU is designed with sufficient protection measures to ensure their program codes’ safety. Simultaneously, this MCU series does not have the PROGRAM READ function, so the programmer cannot read them. (Note: The verification function when programming the chip with the programmer is not to read the program for verification, but the programmer sends the data to the chip, and the chip core independently completes the comparison with the data in the storage area and then compares the result Return to the programmer).

The intrusive cracking method can turn the encrypted chip into a non-encrypted chip in the chip decryption industry and then use the programmer to read the program. Of course, you can also use the probe to read the program from the chip’s internal bus, but its cost is relatively high; the non-intrusive cracking method usually needs to read the program through the programmer. In this way, the NEC series MCU cannot be cracked using conventional decryption methods.

 Our company has long been devoted to developing various complex IC decryption solutions in the chip decryption industry and dares to challenge the industry’s technical problems. For the NEC series of complicated crack chips, our professional engineers specially developed the NEC microcontroller program reading tool, which solved the problem that the NEC chip programs that troubled various technical engineers could not be read.

 Suppose customers have NEC series UPD78FXX, UPD79F, and other MCU decryption needs. In that case, we can provide samples for our decryption engineers to test and analyze while considering their product development value and later chip purchases. Generally speaking, NEC series MCUs are divided into two types with and without OTP. During the testing process of the project, destructive methods are typically used for testing. Therefore, if customers have cracking requirements, they generally need to provide at least three samples. , One for testing and the other two for the specific cracking process.

NEC series MCUs are challenging to crack, and the specific decryption methods of almost every chip are different. At present, there are no ready-made crack solutions available. Therefore, for this series of chips, our engineers need to re-develop the cracking method. The required cycle generally takes 20 working days. Around the same time, I also hope that customers will fully consider the product development value while accounting for the product development cycle.
