EFR32FG22C121F512GM40

Proprietary 2.4 GHz EFR32FG22 SoCs (Series 2)

EFR32FG22C121F512GM40 EFR32FG22 Series 2 wireless SoCs include a 38.4 MHz ARM Cortex-M33 core, providing plenty of processing capability, while integrated security features provide fast encryption, secure boot loading and a debug access control. This device includes 512 kB of flash, 32 kB of RAM and is available in a QFN40 package. With up to 6 dBm maximum power output and an excellent receive sensitivity of -102.1 (250 kbit/s OQPSK) dBm, the EFR32FG22C121F512GM40 provides a robust RF link for reliable communications and industry-leading energy efficiency for electronic shelf label, building automation and industrial wireless sensor applications. EFR32FG22C121F512GM40 devices use the same tools as EFR32FG Series 1, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps and our patented network analyzer.
