DS2475 Series

DeepCover®embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.The DeepCover Elliptic Curve Digital Signature Algorithm (ECDSA) coprocessor with built-in 1-Wire®master (DS2475) enables the efficient implementation of public- key based authentication when combined with an ECDSA secure authenticator. Additionally, for operation with 1-Wire ECDSA authenticators, an I2C-to-1-Wire protocol conversion function relieves the system host processor from generating time-critical 1-Wire waveforms. The DS2475 interfaces directly to standard (100kHz max) or fast (400kHz max) I2C masters. When not in use, the DS2475 can be put in sleep mode where power consumption is minimal.ApplicationsAuthentication of AccessoriesAuthentication of ConsumablesPeripheral Authentication
