UWB Smart Lock Solution

The UWB smart lock solution adds UWB capability on top of our second-generation smart lock platform. It enables hands-free unlocking when you approach the door from outside, automatic locking once you move away from the lock, and no unlocking when the key is inside the room. It delivers accurate ranging and solid security while making unlocking completely hands-free.

Recommended MCU

• LPC55S00 series: LPC55S69 — the world's first microcontroller based on the general-purpose Cortex® -M33; built on the Armv8-M architecture with TrustZone-M, a coprocessor and a dual-core design; raises the balance of performance and power efficiency and the level of advanced security to a new height; a proprietary DSP accelerator cuts computation time by 10x compared with CMSIS-DSP; built on cost-effective 40nmNVM process technology
• UWB100: supports AT-command customization of UWB parameters for interoperability with other UWB devices; the multi-antenna design suits different application scenarios and supports single-channel TOF, dual-channel TOF and 2D AOA; UWB complies with the FiRa Consortium™ MAC/PHY standard; UWB supports channel 5 and channel 9; high-accuracy two-way ranging (±10 cm) and angle measurement (±3°); low-power modes supported, with 107uA@3.3V in power-down mode

Key Features

• Inherits every function of the original second-generation lock
• Smartphone UWB key support: works with Apple phones (iPhone 11 and later) and supports background operation of the app
• Intelligent hands-free unlocking: unlocks automatically within the unlock range and locks automatically beyond the lock range
• Intelligent UWB key position detection: unlocks automatically when the key is outside the door, and never triggers automatic unlocking wherever the key is inside
• Meets the existing low-power requirements of door locks
