EFR32FG25 Sub-GHz Wireless SoCs

Coming Soon

EFR32FG25 wireless SoCs are an ideal solution for long range, Sub-GHz wireless connectivity for smart metering, lighting, city and building automation. The inclusion of multi-rate OFDM, FSK, and OPSK modulation schemes allows for data rates up to 2.4 Mbps while keeping immunity to 2.4 GHz interference. The large memory footprint and increased IO count allows for design consolidation and when combined with Secure Vault™ can provide higher level system security.
