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.

The EFR32BG26 Bluetooth SoCs are ideal for IoT wireless connectivity using Bluetooth Low Energy and Bluetooth mesh for smart home, lighting, and portable medical products. With key features like high-performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator, and Secure Vault™, IoT device makers can create the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. An ARM Cortex®-M33 running up to 78 MHz and up to 2048 kB of Flash and 256 kB of RAM provides resources for demanding applications while leaving room for future growth. Target applications include gateways/hubs, sensors, switches, smart plugs, LED lighting, and luminaires.

Wireless Gecko Series 2 devices are the next evolution of Wireless Gecko devices bringing high performance, low power, and secure solutions to the Internet of Things. Designed to increase processing capability, improve RF performance and lower active current, the devices also provide the highest level of IoT device security. The EFR32BG21 devices are also designed to support Silicon Labs' enhanced security option, Secure Vault. Learn more about Silicon Labs' security portfolio.

EFR32BG21 devices are 2.4 GHz wireless SOCs optimized for line-powered Bluetooth Low Energy and Bluetooth mesh applications, including connected lighting, smart plugs, gateways and voice assistants. An 80 MHz ARM® Cortex®-M33 core provides plenty of processing capability while an integrated security subsystem provides leading security features that greatly reduce the risk of IoT security breaches and compromised intellectual property. With better than -104.3 dBm sensitivity and up to +20 dBm output power, the EFR32BG21 family uses Simplicity Studio 5 development tools, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps, our energy profiler and patented network analyzer.

The EFR32BG24 Wireless SoCs are ideal for IOT wireless connectivity using Bluetooth Low Energy and Bluetooth mesh for smart home, lighting, and portable medical products. With AECQ-100 qualification, support for Channel Sounding, and key features like high performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator and Secure Vault™, IoT device makers can create the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. An ARM Cortex®-M33 running up to 78 MHz and up to 1.5 MB of Flash and 256 kB of RAM provides resources for demanding applications while leaving room for future growth. Target applications include gateways/hubs, sensors, switches, door locks, smart plugs, LED lighting, luminaires, blood glucose meters and pulse oximeters.
