DS28E40 Deep Cover Automotive 1-Wire Authenticator

The DS28E40 is a secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware-implemented cryptographic engines, the device integrates a FIP.
