• 6LoWPAN IoT node implementations
• High data rate ISM band applications

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'ZUR' indicates the tape and reel packaging variant distinct from tray options. Confirm the 48-pin VFQFN package dimensions match the target PCB footprint. Ensure the industrial temperature rating aligns with environmental requirements. Cross-reference the datasheet revision for any pinout or electrical characteristic updates prior to finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for 2.4 GHz protocols. The 256 KB Flash capacity supports complex application logic alongside protocol stacks. Consider the 32 KB SRAM size for buffer management in high-throughput scenarios. Evaluate the 1.8 V to 3.6 V operating range against available power supply rails in the target design.

RF Transceiver ICS Part Context

This part belongs to the ATmegaRFR2 series of single-chip solutions designed for low-power wireless applications. It complements variants like the ATMEGA128RFR2 and ATMEGA64RFR2 by offering increased memory resources while maintaining the same interface and radio standards. The series targets developers needing integrated processing and communication without external RF components.
