Access Control/Keyless Entry

Electronic access control has become increasingly common in commercial, residential and automotive environments. The mechanical key is being replaced by a number of alternative solutions that allow for dynamic and personalized entry control. Silicon Labs provides many of the blocks required to implement cost-effective and extremely low power solutions.



Solutions for Access Control and Keyless Entry


Silicon Labs Solutions   Customer Benefits

Human-Machine Interface: Low power proximity detection and ambient light sensing

Senses an individual’s presence and can control power to LCD display backlights or RF inductive loops to ensure the lowest possible current consumption

Wireless Range and Robustness: Wireless interface for individual and backhaul data in frequencies from 240 to 960 MHz

Single chip RF transmitter design; can directly drive a loop antenna (removing the need to create complex RF matching networks), embeds an MCU and LC oscillator for true SoC transmitter

Extremely robust RF links that allow for both short range individual communication or long range back haul communication

Lowest cost solution; reduces circuit design to only the RFIC and a capacitor

Precision Processing: Capable of full-spec operation down to 0.9 V and up to 3.6 V, single-cell battery operation; Integrated dc-dc converter, fast wakeup time, low active-mode and ultra-low sleep mode current consumption

Extremely long battery life and fewer battery replacements; maintains accurate time over long time periods

Ethernet Connectivity and Power: Small, high-performance Ethernet controller complete with royalty free Ethernet stack; used with the Si34xx PoE device, system power can be provided via standard Ethernet cabling

Lower system power usage using Ethernet
