Nordic’s nRF5340 SoC incorporates an Arm CryptoCell-312 cryptographic accelerator offering best-in-class security for Cortex-M based SoCs, and Arm TrustZone for system-wide hardware isolation for trusted software. The Arm CryptoCell-312 provides hardware-accelerated cryptography, ensuring the Anona Holo smart lock is secure and reliable, essential for building consumer confidence in smart home security solutions. Arm TrustZone provides trusted execution by implementing a division between secure and non-secure Flash, RAM, peripherals, and GPIOs.
Powered by four AA batteries, the smart lock has an estimated lifetime of between four and six months before battery replacement, or eight months in low power mode (when performing 10 locks and 10 unlocks or fewer per day with a good Wi-Fi connection). This extended battery life is achieved thanks in part to the ultra low power operating characteristics of the nRF5340 SoC.
“Nordic has a leading position in wireless SoCs and the nRF5340 gives us not only a world first multicore SoC, but also the Flash and RAM memory needed to support Matter, and class leading power consumption performance,” says Yang Sheng, CTO, Anona Security Technology Limited. “The nRF7002 provides optimal coexistence with the nRF5340 and Bluetooth LE, as well as good performance on power consumption, connection stability, and of course security.
“Combined with Nordic’s fast response and professional technical support, we were able to greatly reduce our development time.”
