Overview
Description
Smart locks are a rapidly growing segment of the home and building automation industries. These locks communicate with smart home systems through fingerprint recognition or mobile devices using Bluetooth®, Wi-Fi®, or near-field communication (NFC). In this design, the GreenPAK™ family of cost-effective nonvolatile memory (NVM) programmable devices provides motor driver and LED control functions, while a high-performance 32-bit MCU supports fingerprint modules with algorithm integration.
System Benefits:
- Supports multiple protocols, including Bluetooth 5.1, Wi-Fi, and NFC, for seamless connectivity
- Combines a 160MHz Arm® Cortex®-M33 with dual-band Wi-Fi 6 and Bluetooth Low Energy (LE), enabling always-connected smart locks with sub-µA sleep currents for extended battery life
- Integrates an NFC reader IC and programmable mixed-signal matrix to consolidate multiple system functions into a single custom circuit
- Offers a low pin count for efficient fingerprint algorithm integration
