EFR32FG23 Flex Gecko Wireless SoCs

Silicon Labs EFR32FG23 Flex Gecko Wireless SoCs (System-on-a-Chip) are ideal for sub-GHz loT 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, low power consumption with fast wakeup times. An integrated power amplifier to enable the next generation of secure connectivity for loT devices. 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.
