Energy Harvesting

EFR32BG22 and EFR32BG22E Bluetooth low energy (LE) wireless SoC solutions are part of the Wireless Gecko Series 2 platform. These devices are designed with a strong focus on energy efficiency, offering best-in-class ultra-low transmit and receive power, and a high-performance, low-power Arm® Cortex®-M33 core delivers industry-leading energy efficiency that can extend coin cell battery life up to ten years. Where BG22 allows you to create energy-efficient applications, the BG22E – ‘E’ denoting Energy Conservation – takes this a step further by enhancing battery longevity and supporting designs that eliminate the need for batteries altogether. Our BG22 and BG22E family's are the ideal market leading SoCs for Ambient IoT or Energy Harvesting devices. Target applications include Bluetooth mesh low-power nodes, smart door locks, personal healthcare and fitness devices. Asset tracking tags, beacons and indoor navigation also benefit from the SoCs' versatile Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) capabilities and sub-one-meter location accuracy.

The EFR32BG27 family of wireless SoCs opens up new possibilities by offering an ultra-small WLCSP package (2.3 mm x 2.6 mm) capable of running on button cell batteries. Now device makers can address applications with extremely small form-factor requirements without sacrificing performance and security. The BG27 Bluetooth SoC features an integrated DCDC boost that allows operation down to 0.8 volts, enabling support for single-cell alkaline and 1.5-volt button cell batteries that are typically used in medical applications for battery-operated patches and continuous glucose monitoring (CGM) devices. Additionally, the wakeup pin on the BG27 allows products in a warehouse or transit to remain off for months, consuming less than 20 nA, ensuring the battery remains fully charged for use. The integrated coulomb counter enables accurate battery level monitoring to avoid unexpected battery depletion for critical applications. Target applications include connected medical devices, wearables, sensors, switches, smart locks, and both commercial and LED lighting.

EFR32MG22 and EFR32MG22E Zigbee SoC (system-on-chip) solutions are part of the Wireless Gecko Series 2 platform. The MG22 family offers an optimized Zigbee SoC solutions incorporating a high-performance, low-power 76.8 MHz Arm® Cortex®-M33 core with TrustZone. Where MG22 allows you to create energy-efficient applications, the MG22E – ‘E’ denoting Energy Conservation – takes this a step further by enhancing battery longevity and supporting designs that eliminate the need for batteries altogether. The MG22 SoCs’ combination of ultra-low transmit and receive power (8.2 mA TX at +6 dBm, 3.9 mA RX), 1.4 µA deep-sleep mode power and low-power peripherals delivers an industry-leading, energy-efficient solution for applications using the Zigbee protocol including Green Power. IoT applications include smart home sensors, lighting controls, and building and industrial automation.

EFR32FG22 and EFR32FG22E proprietary wireless 2.4 GHz SoC solutions are part of the Wireless Gecko Series 2 platform. FG22 SoCs integrate a 38.4 MHz Arm® Cortex®-M33 core with TrustZone and a high-performance radio with a receive sensitivity of -102.3 dBm. Where FG22 allows you to create energy-efficient applications, the FG22E – ‘E’ denoting Energy Conservation – takes this a step further by enhancing battery longevity and supporting designs that eliminate the need for batteries altogether. The SoC's combination of ultra-low transmit and receive power (8.2 mA TX at +6 dBm, 3.6 mA RX), 1.2 µA deep-sleep mode power and innovative low-power features such as RFSense delivers industry-leading energy efficiency to extend the operational life of products with limited battery or energy harvesting options such as those used by electronic shelf labels and industrial wireless sensor nodes.
