DS3650：DeepCover Security Manager with Thermal Tamper Detection

Single-Chip Solution Integrates Advanced Physical Security with On-Chip Encryption Key Destruction

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 (DS3650) is a 4-wire-compatible controller specifically intended to address the temperature and voltage monitoring requirements of the payment card industry (PCI) and other equipment where data protection and security is critical. The device incorporates a battery-backup controller, system power monitor, CPU supervisor, temperature sensor, and two tamper detection comparator inputs for interface to external sensors, interlocks, or antitamper meshes. In the event of primary power failure, an external battery power source is automatically switched in to keep the tamper-detection circuitry alive.
