Product Details

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.
The DeepCover Security Manager (DS3655) is a tamper-reactive memory device specifically intended to address the requirements of equipment where data protection and security is critical. The device contains 64 bytes of a proprietary nonimprinting memory that can be erased in less than 100ns. The device contains a temperature sensor, as well as four tamper-detect logic inputs for interface to external sensors, interlocks, or antitamper meshes. Communication is conducted through an I²C-compatible interface.

In the event of a primary power failure, an external battery source is automatically switched in to keep the internal memory, elapsed-time counter, and tamper-detection circuitry alive. Additionally, output signals are provided to flag a tamper event, monitor the internal oscillator, and power external circuitry from either the system supply or the battery.
