8k x 8 Secure Memory with Programmable Tamper-Response Hierarchy and RTC

Industry's First 8kB Secure Memory with Tamper-Response Hierarchy

Viewing:

Overview

  • Four-Level, Programmable Tamper-Response Hierarchy
  • Selectable Memory Clearing
  • Four Independent Tamper-Detection Interrupt Outputs
  • 8kB Battery-Backed Key Memory with High-Speed Erase
  • Controls External SRAM for Battery-Backup Operation and Optional Tamper Event Erase
  • Programmable Power Consumption
  • Battery-Backup Controller
  • 64-Bit Unique Silicon Serial Number

    • The DS3665 is a highly integrated, encryption-key supervisor designed to address the circuit requirements associated with the storage of sensitive data, as well as for the physical tamper-sensing-response functions utilized in high-end cryptographic processors and related data security equipment.
