Overview

Electronic smart locks are growing as a result of IoT. These battery-powered locks often require features such as BLE, Sub-1 GHz, Wi-Fi connectivity, interactive RGBW HMI, audio and sensing and more. Our integrated circuits and reference designs help you address complex design issues while reducing time to market.

Design requirements

Electronic smart lock designs require:

  • Energy efficiency and long battery life with a wide operating temperature range.
  • Secure management of keys and access control.
  • Low-power HMI like RGBW LEDs, touch, proximity sensing and audio notification.
  • Support of multiple industry standards like ZigBee®, 6LoWPAN and ZigBee RF4CE remote control applications.
  • Configurable BLE advertisement intervals to reduce power consumption.
