Silicon Labs


EFR32BG22 融合了領導業界的安全性、無線效能、功耗、軟體工具和協定堆疊,可滿足大量生產、電池供電型物聯網產品市場需求。其功能擴展了 Wireless Gecko Series 2 平台,使開發人員能透過最佳化藍牙連接解決方案支援最新藍牙 5.2 技術規範。
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.

- 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, providing 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.

- Securing Your Bluetooth Product
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.
