New xG22E family of Wireless SoCs, Silicon Labs’ first-ever family designed to operate within the ultra-low power envelope required for battery-free, energy harvesting applications. The new family consists of the BG22E, MG22E, and FG22E. As Silicon Labs’ most energy-efficient SoCs to date, all three SoCs will enable IoT device makers to build high-performance, Bluetooth Low Energy (LE), 802.15.4-based, or Sub-Ghz wireless devices for battery-optimized and battery-free devices that can harvest energy from external sources in their environments like indoor or outdoor ambient light, ambient radio waves, and kinetic motion.

Ultra-fast, low-energy cold start for applications starting from a zero-energy state to transmit packets and then rapidly return to sleep. An xG22E device wakes up in only eight milliseconds and uses only 150 micro-Joules, or roughly 0.003% of the energy needed to power a 60-watt equivalent LED lightbulb for one second
Energy conserving deep sleep swift wake-up reduces wake-up energy by 78% compared to other Silicon Labs devices
Power-efficient energy mode transition to smoothly transition in and out of energy modes by mitigating current spikes or inrush, which can harm energy storage capacity
Multiple deep sleep wake-up options, such as RFSense, GPIO, and RTC wake-up sources from the deepest EM4 sleep mode, are ideal for extended storage
