Exact-Part Selection Insight
The exact STM32U5A5RJT6 orderable code ties 4MB program memory to the LQFP-64(10×10) implementation and 51 listed I/O. Moving to a nearby family member can change memory capacity or pin availability, so the firmware memory map and PCB pinout should be checked together rather than treating the family name as interchangeable.
Selection Notes
- Package: LQFP-64(10×10)
- Supply voltage: 1.71V~3.6V
- CPU Core: ARM Cortex-M33
- Maximum CPU speed: 160MHz

Application Fit
This exact part is appropriate for designs that require a microcontroller with the confirmed package and electrical/function parameters above. Final fit depends on the surrounding circuit, interface, thermal and mechanical requirements of the target design.
Design Considerations
Confirm the available supply rail stays inside the stated operating range, including startup and transient conditions.
Confirm memory size, available I/O, clocking and required peripheral set for the exact orderable device before freezing firmware and PCB pinout.
Use the exact LQFP-64(10×10) footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.
