EFR32ZG23A010F512GM40-B

Overview

The EFR32ZG23A010F512GM40-B is a Sub-GHz RF System on Chip (SoC) from Silicon Labs, designed for Z-Wave and ISM applications. It integrates an ARM Cortex-M33 core operating at up to 78 MHz with 512 kB of Flash memory and 64 kB of RAM. The device supports frequencies between 863-870 MHz and 902-928 MHz, delivering +14 dBm output power and -110 dBm sensitivity. It features a maximum data rate of 100 kbps, operates within a 1.71 V to 3.8 V supply range, and is housed in a QFN-40 package.

Feature Summary

• Integrates an ARM Cortex-M33 processor with hardware cryptographic acceleration for secure communication.
• Supports Z-Wave Long Range and standard Z-Wave protocols with optimized low-power performance.
• Includes high-sensitivity receiver architecture enabling reliable connectivity in noisy environments.

Applications

• Z-Wave smart home devices
• ISM band wireless sensors
• Low-power IoT gateways

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout compatibility and regulatory certifications. Ensure the order matches the exact memory configuration and frequency band requirements. Cross-reference the revision level with any applicable errata documents to account for known silicon revisions before finalizing procurement.

Selection Notes

Select this component when Z-Wave protocol support and long-range reliability are prioritized over raw data throughput. The 100 kbps limit distinguishes it from higher-speed FG series variants. Evaluate the +14 dBm output against antenna design constraints to ensure compliance with regional emission regulations while maintaining adequate link budget for the intended deployment environment.

Part Context

This part belongs to the EFR32ZG23 family, specialized for Z-Wave applications. Unlike the FG series which targets general Sub-GHz use, the ZG series includes dedicated hardware accelerators for Z-Wave security and protocol handling. It shares the same physical footprint as other QFN-40 variants but differs in internal software optimization and certified protocol stacks.

Replacement Considerations

Direct replacements include other EFR32ZG23 variants with matching memory sizes, such as EFR32ZG23A010F512GM40-CR, provided the package and pinout remain compatible. Verify that alternative parts support the required Z-Wave certification status if regulatory approval is mandatory for the end product.
