EFR32BG22

Bluetooth device shipments are forecast to grow 26 percent by 2023 (from 4 billion units in 2019 to 5.4 billion units). Silicon Labs designed the EFR32BG22 (BG22) SoCs to meet the unique requirements of high-volume, battery-powered Bluetooth products. Featuring an ultra-low transmit and receive power (3.6 mA TX at 0 dBm, 2.6 mA RX) and a high-performance, low-power M33 core (27 µA/MHz active, 1.2 µA sleep) – BG22 delivers industry-leading energy efficiency that can extend coin cell battery life beyond five years.

EFR32BG22 Series 2 Bluetooth® Wireless SoC

EFR32BG22 (BG22) Bluetooth low energy (LE) wireless SoC solutions are part of the Wireless Gecko Series 2 platform. The BG22 family's combination of best-in-class ultra-low transmit and receive power (4.1 mA TX at 0 dBm, 3.6 mA RX) and a high-performance, low-power Arm® Cortex®-M33 core (27 µA/MHz active, 1.2 µA sleep) delivers industry-leading energy efficiency that can extend coin cell battery life up to ten years. 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.

FEATURES

Automate

The EFR32BG22C224 SoC provides IQ sampling and access to 125 kB and 500 kB Bluetooth LE Coded PHYs, which can increase RX sensitivity to -106.7 dBm. The SoC increases operating temperature to +125 ºC and extends flash memory up to 512 kB to support applications requiring direction finding capabilities or low-power mesh nodes.

Connect

EFR32BG22C222 SoC targets applications requiring more compute power (with a 76.8 MHz M33 core), more I/Os (up to 26 GPIOs) and higher TX power (+6 dBm).

Locate

The EFR32BG22C112 SoC targets high-volume, cost-sensitive applications such as asset tracking tags by eliminating the need for an external sleep crystal. These SoCs provide access to 1 Mbps and 2 Mbps Bluetooth PHYs, along with a 38.4 MHz Arm® Cortex®-M33 core, 18 GPIOs and 352 kB of flash memory with radio characteristics of 0 dBm transmit (TX) and an industry-leading -99 dBm receive (RX) (1M PHY) sensitivity.

BG22 Security Features

IoT security is key to protecting company brands, end user privacy and commercial viability of products. Vulnerabilities can be exploited through both remote Internet attacks and physical hands-on-attacks.
Developers using the Silicon Labs wireless product portfolio including those in the EFR32BG22 portfolio have access to a number of technologies designed to protect their product, including Secure Boot with Root of Trust, Secure Loader and Secure Debug.
