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.
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.
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).
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.
