RF Receivers Procurement Notes

Verify the specific suffix 'I/LQ' against official Microchip documentation to confirm industrial temperature rating and LQFP-32 packaging. Ensure compatibility with target PCB footprint dimensions of 7x7 mm. Confirm that the intended application does not require FM demodulation capabilities, as this variant is optimized for ASK/FSK protocols.

RF Receivers Selection Notes

Select this component when a cost-effective, integrated solution for short-range UHF reception is required. It is suitable for designs prioritizing reduced bill-of-materials count due to its internal microcontroller and minimal external circuitry requirements. Consider the 300-450 MHz operational window and 80 kbps maximum data rate constraints during system planning.

RF Receivers Part Context

This part belongs to the rfRXD0420/0920 family of UHF receivers designed for short-range applications. These modules are characterized by their low profile and high integration levels, distinguishing them from discrete receiver solutions.
