Procurement Notes

Verify the specific ordering suffix GM40-BR corresponds to the required tape and reel packaging quantity and lead time status through authorized distributors. Confirm that the temperature range and voltage supply specifications meet your system requirements before finalizing procurement orders.

Selection Notes

Select this component when Zigbee or Thread connectivity is required alongside moderate processing power. Ensure the application benefits from the integrated radio performance and low power modes available in the Series 2 family compared to previous generations.

Part Context

This model belongs to the EFR32ZG23 series designed for cost-sensitive Zigbee and Thread nodes. It shares the same core architecture as other variants in the family but differs in memory size and package type. The ZG designation indicates a general-purpose Zigbee focus within the broader Gecko portfolio.

Replacement Considerations

Direct replacements include other EFR32ZG23 variants with compatible pinouts and similar memory configurations. Cross-reference with EFR32ZG22 series parts if lower performance thresholds are acceptable, ensuring software compatibility with existing firmware libraries.
