EFR32MG21B020F512IM32-B

EFR32MG21B020F512IM32-B EFR32MG21 Series 2 wireless SoC includes a 80MHz ARM Cortex-M33 core, providing plenty of processing capability while an integrated security subsystem provides leading security features that greatly reduce the risk of IoT security breaches and compromised intellectual property. The device includes Secure Vault, 512KB flash, 64KB RAM and is available in a QFN32 package. With up to + 20dBm maximum power output and excellent receive sensitivity of -104 (250 kbps O-QPSK DSSS) dBm, this provides a robust RF link for reliable communications for Zigbee, thread and multiprotocol applications and enables greater range and reliable RF communications. It uses Simplicity Studio 5 development tools, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps and our patented network analyser. Typical applications are IoT multi-protocol devices, lighting, connected home, gateways and digital assistants, building automation and security.
