EFR32FG23 Flex Gecko Wireless SoCs

Silicon Labs EFR32FG23 Flex Gecko Wireless SoCs (System-on-a-Chip) are ideal for sub-GHz Internet of Things (IoT) wireless connectivity for smart home, security, lighting, building automation, and metering. The EFR32FG23 are high-performance sub-GHz radios that provide long-range and are not susceptible to 2.4GHz interference from technologies. The single die, multi-core solution provides industry-leading security and low power consumption with fast wakeup times. An integrated power amplifier enables the next generation of secure connectivity for IoT devices. The EFR32FG23L variants are low-power. Silicon Labs EFR32FG23 Flex Gecko Wireless SoCs are available in 40-pin and 48-pin Quad Flat No-Lead (QFN) packages with a wide -40°C to +125°C operating temperature range.
