Series 2 SoCs provide developers with unmatched system design advantages:

• Best-in-class RF performance with +20 dBm output power and up to +124.5 dB link budget
• Robust wireless radio with improved blocking performance
• Powerful processing with an 80 MHz Arm® Cortex®-M33 core with TrustZone technology
• Low active current (50.9 µA/MHz) to meet stringent green energy requirements, a benefit of manufacturing on low-power 40 nm process technology
• Industry’s smallest multiprotocol SoCs in a 4 mm x 4 mm QFN package
• Lower BOM count and system cost with fewer matching components and no need for external inductors or power amplifiers
• Flexible pre-certified modules based on EFR32xG21 SoCs planned for Q3
• Secure by Design

EFR32xG21 SoCs provide enhanced security features that enable developers to implement robust security in connected products:

• A dedicated security core enables faster, lower-power encryption than software techniques.
• A true random number generator (TRNG) strengthens device cryptography.
• Secure boot loading ensures authenticity of firmware images and over-the-air updates.
• Secure debug access control helps OEMs prevent unauthorized access to end products.
