SILICON LABS EFR32FG23B020F512IM48-BR

The EFR32FG23 SoC is an ideal solution for sub-GHz “Internet of Things” applications in smart homes, security, lighting, building automation, and metering. The high-performance sub-GHz radio provides long range capabilities and is not susceptible to 2.4 GHz interference from technologies like Wi-Fi. The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and an integrated power amplifier to enable the next level of secure connectivity for IoT devices.
