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 (DS24L65) 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. For 1-Wire line driving, internal user-adjustable timers relieve the system host processor from generating time-critical 1-Wire waveforms, supporting both standard and overdrive 1-Wire communication speeds. The 1-Wire line can be powered down under software control. Strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs. When not in use, the DS24L65 can be put in sleep mode where power consumption is minimal.
A DS24L65 evaluation board is included in each of the authenticator evaluation kits below.
