RF Transceiver ICS Procurement Notes

Verify the specific suffix T0RGZR against the official datasheet to confirm the tape and reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the VQFN-48 package. Cross-reference the part number with Texas Instruments documentation to validate manufacturing status and lifecycle stage before finalizing procurement plans.

RF Transceiver ICS Selection Notes

Select this component when sub-1 GHz frequency bands are required for long-range connectivity. The high flash capacity suits complex firmware requirements. Evaluate the 48 MHz processing speed against application latency needs. Confirm that the VQFN-48 package dimensions fit the mechanical constraints of the target design.

RF Transceiver ICS Part Context

This part belongs to the CC1311R3 series within the SimpleLink portfolio. It shares architectural similarities with other members like the CC1311R31T0RKPR but differs in package type and specific pinout configurations. The series is optimized for cost-effective, low-power wireless solutions using standard sub-1 GHz ISM bands.

RF Transceiver ICS Replacement Considerations

Direct substitutes include the CC1311R31T0RKPR, which offers identical electrical specifications but utilizes a different QFN package variant. Verify pin-to-pin compatibility and reflow soldering profiles when transitioning between package types.
