Microcontrollers Procurement Notes

Verify the specific suffix M445T corresponds to the tape and reel packaging configuration when ordering. Confirm that the AZA variant meets the required automotive or industrial qualification standards for your specific application environment. Ensure compatibility with the 64-TQFP footprint during PCB layout finalization.

Microcontrollers Selection Notes

Select this model if 64 kB of Flash memory is sufficient for the application firmware requirements. Consider alternative pin counts if more than 51 general-purpose I/O pins are needed. Verify that the 48 MHz processing speed aligns with real-time execution constraints. Ensure the 1.71 V minimum operating voltage matches the system power rail design.
