RF Transceiver ICS Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm regional compliance or temperature grade variations. Ensure the QFN-40 package dimensions match the target PCB footprint. Confirm that the 256 kB Flash configuration meets the firmware storage requirements before finalizing the bill of materials.

RF Transceiver ICS Selection Notes

Select this model when a balance of moderate program memory and high RF output power is required for Sub-GHz links. Compare against variants with larger RAM if complex protocol stacks are needed. Consider the QFN-40 form factor for space-constrained designs requiring surface-mount assembly.

RF Transceiver ICS Part Context

This component belongs to the EFR32FG23 Series 2 family, which is certified for PSA Level 3 and SESIP Level 3 security standards. The series utilizes common development tools and SDKs, facilitating migration between different memory and performance tiers within the same product line.

RF Transceiver ICS Replacement Considerations

EFR32FG23A020F512GM40-C offers identical RF and core specifications but provides 512 kB Flash and 64 kB RAM. EFR32FG23A011F512GM40-C shares the memory size but reduces output power to +14 dBm.
