The second-generation smart lock solution is our follow-up to the first-generation smart lock solution, developed out of a strong commitment to data security at the edge. A smart lock is the last line of defense for every household, and its fundamental purpose comes down to one thing: security. That is why the second-generation solution integrates an energy-efficient dual-core Cortex®-M33 processor with TrustZone, the high-security real-time PRINCE encryption peripheral and the SRAM PUF key generation and management peripheral — delivering all-round protection and keeping every household safe.
Recommended MCU
- LPC55S00 series: LPC55S69: the world's first microcontroller based on the general-purpose Cortex®-M33; built on the Arm®v8-M architecture with TrustZone-M, a coprocessor and a dual-core design; raises the balance of performance and power consumption, together with the level of advanced security, to new heights; a proprietary DSP accelerator cuts computation time by 10x compared with CMSIS-DSP; based on 40nm NVM process technology for cost-effectiveness
