DS2465P+ by Analog Devices

DeepCover Secure Authenticator with SHA-256 Coprocessor and 1-Wire Master Function


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. 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 DS2465 can be put in sleep mode where power consumption is minimal. A DS2465 evaluation board is included in each of the authenticator evaluation kits below.
