DS2477 Secure I2C Coprocessor Analog Devices DS2477 Secure I2C Coprocessor combines a hash algorithm (SHA-3) authentication with ChipDNA™ feature for solutions against security attacks. The DS2477 utilizes the ChipDNA output as key content to secure all device-stored data cryptographically. Attempts to probe or observe ChipDNA operation modify the underlying circuit characteristics preventing the discovery of the unique value used by the chip's cryptographic functions. The ChipDNA circuit uses a random variation of semiconductor device characteristics occurring naturally during wafer fabrication. The circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. The circuit provides a core set of cryptographic tools derived from integrated blocks. Analog Devices DS2477 Secure I2C Coprocessor provides the SHA-3 and memory functionality a host system requires to communicate with and operate a 1-Wire® SHA-3 slave.
