Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when sourcing components. Confirm that the 'L' designation corresponds to the lower voltage operating range of 2.7V to 5.5V. Ensure compatibility with existing PCB footprints for the 32-lead TQFP package. Check current lifecycle status as older variants may be marked as not recommended for new designs.

Selection Notes

Select this component for applications requiring a balance of processing speed and power efficiency at lower voltages. The 8MHz speed grade is suitable for moderate throughput requirements. Consider the TQFP package for surface mount assembly needs. Evaluate the available I/O lines and peripheral counts against system interface requirements before finalizing the selection.
