Procurement Notes

Verify the specific suffix 'QMSR' against the manufacturer's official datasheet to confirm package type and temperature grade. Check current availability status as supply constraints may affect lead times. Ensure compatibility with existing PCB footprint designs using the TQFN-64 package dimensions.

Selection Notes

Select this component when a combined MCU and power driver solution is required for 70V BLDC applications. Consider the integrated CAFE for simplified sensor signal conditioning. Evaluate the need for the specific memory configuration (32KB Flash, 8KB SRAM) against application algorithm complexity.

Part Context

The PAC55723 belongs to Qorvo's PAC family, which consolidates power management, analog front-end, and MCU functions. This integration reduces bill-of-materials count and board space compared to discrete solutions. It is part of a broader portfolio including variants like PAC55710 and PAC55713, tailored for different voltage and performance tiers.

Replacement Considerations

Direct substitutes within the same PAC family include PAC55710QMSR and PAC55713SR, though pinouts and feature sets may differ. Verify functional equivalence regarding GPIO mapping and peripheral availability before replacement.
