VirtualZero Always Connected

VirtualZero Always Connected

VirtualZero™ delivers ultra-low power Wi-Fi for always-connected IoT—meeting standby regulations for wall-powered devices and extending battery life in portable products without compromising latency and connectivity.

Flexible Architecture

Flexible Architecture

Standalone mode allows a user app to run on the Wi-Fi MCU. Attached mode lets the Wi-Fi MCU handle connectivity for another MCU. Memoryless radio-co-processor (RCP) mode operates without onboard memory.
