EFR32FG23B020F128GM40

EFR32FG23 Series 2 SoCs

EFR32FG23B020F128GM40 EFR32FG23 Series 2 wireless SoCs include a 78 MHz ARM Cortex-M33 core, providing plenty of processing capability, while a dedicated security core provides fast encryption, secure boot loading and a debug access control. This device includes 128 kB of flash, 32 kB of RAM and is available in a QFN40 package. With up to 20 dBm maximum power output and an excellent receive sensitivity of -125.8 (4.8 kbps OQPSK @ 915 MHz) dBm, the EFR32FG23B020F128GM40 provides a robust RF link for reliable communications for sub-GHz proprietary applications. EFR32FG23B020F128GM40 devices use the same tools as EFR32FG23 Series 2, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps and our patented network analyzer. The EFR32FG23 family is the first Sub-GHz radio to achieve a PSA Level 3 certification and SESIP Level 3 certification.
