The High-Efficiency Bluetooth Low Energy Advantage
The EFR32BG22C112F352 represents a premier professional single-protocol low-power Bluetooth (BLE) wireless connectivity SoC solution engineered for space-constrained, battery-critical hardware architectures demanding absolute energy efficiency and robust connection stability profiles. Developed inside Silicon Labs’ advanced BG22 Series 2 framework, this system processes continuous high-frequency Bluetooth 5.2 data transmission and localized smart sensor telemetry loops flawlessly without code execution latency hazards or current draw spikes. Housed in a compact, thermally enhanced 32-pin QFN package format, it secures pure, deterministic low-power software execution loops and completely cuts off hardware energy waste bottlenecks.
- Optimized 352 Kilobytes (352KB) of on-chip flash flash paired with 32 Kilobytes of high-stability RAM
- High-efficiency 76.8MHz ARM Cortex-M33 processing core maximizing computational math throughput safely
- Ultra-low active radio currents (3.6 mA TX at 0 dBm, 2.6 mA RX) maximizing continuous coin-cell device battery lifetimes
