RF Transceiver ICS Procurement Notes

Verify the specific suffix RSMR corresponds to the 32-VQFN (4x4) package with exposed pad. Confirm that the order quantity matches the tape and reel packaging format specified by the manufacturer. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for 2.4GHz networks. It is suitable for designs needing moderate flash capacity and integrated GPIOs. Consider alternative variants if different package sizes or memory configurations are necessary for space-constrained PCB layouts.

RF Transceiver ICS Part Context

This part belongs to the Texas Instruments SimpleLink CC26xx family of wireless MCUs. It shares architectural similarities with other members like the CC2650 but is specifically tuned for 2.4GHz operations. The RSMR suffix denotes the specific surface-mount package type used for high-volume manufacturing integration.

RF Transceiver ICS Replacement Considerations

CC2620F128RGZR offers the same electrical specifications in a different QFN package variant. Cross-reference pinouts and thermal characteristics when substituting to ensure mechanical fit on the existing PCB footprint.
