General Description

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

The DeepCover Secure Authenticator (DS2465) is a SHA-256 coprocessor with built-in 1-Wire® master that provides the SHA-256 and memory functionality required by a host system to communicate with and operate a 1-Wire SHA-256 slave.

In addition, it performs protocol conversion between the I2C master and any attached 1-Wire SHA-256 slaves.
