EFR32xG27 Small 2.4GHz Wireless SoCs

Silicon Labs EFR32xG27 Small 2.4GHz Wireless SoCs are single-die solutions combining a 76.8MHz Cortex-M33 with a high-performance 2.4GHz radio to provide energy-efficient, wireless SoCs for IoT-connected applications. The EFR32BG27 SoCs (WLCSP and QFN packaged) enable BLUETOOTH^® 5.x networking, while the EFR32MG27 components (QFN packaged) permit multiprotocol networking. These devices have boost or buck DC-DC capabilities, allowing for direct power from various battery sources.
