Overview
The EFR32ZG23A010F512GM40-CR is a Sub-GHz RF System on Chip (SoC) from Silicon Labs, designed for Z-Wave and IoT applications. It features an ARM Cortex-M33 core operating at 78 MHz, integrated with 512 kB of Flash memory and 64 kB of RAM. The device supports frequencies below 1 GHz, offering robust wireless connectivity for smart home and building automation systems.
Feature Summary
- Integrates a high-performance ARM Cortex-M33 processor with dedicated security cores for encryption and secure boot.
- Provides advanced RF technology optimized for Sub-GHz proprietary and Z-Wave protocols in a compact package.
- Includes Secure Vault middleware to facilitate PSA Level 3 and SESIP Level 3 certification compliance.
Applications
- Smart home devices
- Home security systems
- Lighting control solutions
- Building automation
Procurement Notes
Verify the specific suffix 'CR' indicates reel packaging if required by your assembly process. Confirm that the A010 variant matches your frequency band requirements. Ensure compatibility with the EFR32FG23 toolchain if migrating from other Gecko Series 2 families. Check current availability status as distribution may vary by region.
Selection Notes
Select this model for applications requiring Z-Wave certification or Sub-GHz proprietary links. The QFN-40 package suits space-constrained designs. Consider the +14 dBm output power for range needs. Evaluate the 78 MHz processing speed against application complexity. Verify support for required peripherals like ADC and digital I/O pins.
Part Context
This component belongs to the EFR32ZG23 series, part of Silicon Labs' Gecko Series 2 family. It shares development tools and SDKs with the EFR32FG23 and EFR32BG23 variants, allowing for flexible migration between different wireless protocol stacks within the same hardware ecosystem.
Replacement Considerations
EFR32ZG23A010F512GM40-C is the tape-and-reel equivalent without the 'R' suffix distinction in some catalogs. EFR32FG23A010F512GM40-C offers similar specs but targets proprietary rather than Z-Wave specific optimizations. Cross-reference pinouts and software libraries when substituting.
