of_sec_puf_sram
SRAM PUF
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Device-unique key derived from SRAM power-up states with enrolment, helper data and error correction.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
Standards
- ISO/IEC 20897-1
Notes
Reliability across ageing and temperature requires silicon data.
