EFR32SG23B020F512IM40-C

EFR32SG23B020F512IM40-C is an EFR32SG23 Amazon Sidewalk SoC. It is the 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 2.4GHz 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. Typical applications are metering, access control, street lighting, energy management.
