nRF54L15 Secure Smart Lock
Build a next-generation secure smart lock with the nRF54L15 — CRACEN hardware crypto for secure BLE key management, tamper detection peripherals, and years of battery life on 2xAA cells.
Build a next-generation secure smart lock with the nRF54L15 — CRACEN hardware crypto for secure BLE key management, tamper detection peripherals, and years of battery life on 2xAA cells.
Platform: nRF54L15
Next-generation ultra-low-power Bluetooth 5.4 SoC with RISC-V and ARM Cortex-M33 cores. Designed for ultra-constrained battery-powered devices.
Use Case: Smart Lock
Bluetooth-enabled smart door lock with secure access control, supporting mobile app unlocking, guest access codes, and activity logging.
Why This Combination
The nRF54L15's CRACEN security engine handles elliptic-curve key generation and BLE LESC pairing entirely in hardware, eliminating software crypto vulnerabilities in access control applications.
