产品信息
产品概述
DS2477Q+U is a DeepCover Secure SHA-3 coprocessor with ChipDNA PUF protection. The DS2477 secure I2C coprocessor with built-in 1-Wire® host combines FIPS202-compliant secure hash algorithm (SHA-3) challenge and response authentication with Maxim’s patented ChipDNA™ feature, a physically unclonable technology (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. The ChipDNA implementation utilizes the random variation of semiconductor device characteristics that naturally occur during wafer fabrication. The ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. Suitable for authentication of medical sensors and tools, secure management of limited use consumables, IoT node authentication, peripheral authentication, reference design license management, printer cartridge identification and authentication.
