DS3605
PRODUCTIONDeepCover Security Manager for NV SRAM Control with RTC and Thermal Tamper Detection
Single-Chip Solution Integrates Advanced Physical Security to Protect Against Physical and Environmental Tamperings
Part Details
- RTC with Leap Year Compensation Valid Up to 2100
- Uses Standard 32.768kHz 6pF Watch Crystal
- Four General-Purpose Tamper Detect Comparators with Associated Reference
- On-Chip Temperature Sensing for Detection of Thermal Attacks
- Programmable Temperature Set-Points
- Programmable Memory Erase Time from 0.01 to 100 Seconds
- Timestamping of Tamper Events
- Integrated CPU Supervisor
- Service and Case Switch Digital Inputs
- On-Chip Random Number Seed Generator
- On-Chip Glitch Filter
- I²C-Compatible Interface
- Low Power Consumption (< 4µA at +25°C)
- 3.0V to 3.6V Single-Supply Operation
In the event of a primary power failure, an external battery source is automatically switched on to keep the internal and external memory, RTC, and tamper-detection circuitry alive. Additionally, output signals are provided to reset the microprocessor, indicate battery operation, and power external circuitry from either the system supply or the battery.
