Procurement Notes

Verify the specific speed grade suffix and core voltage variant when ordering, as these determine electrical characteristics. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the supplier provides official datasheets matching the exact part number to validate pinout and timing parameters before integration into production schedules.

Selection Notes

Select this component for designs requiring moderate logic density with mixed-voltage I/O capabilities. Compare against other MX family members if higher I/O counts or different package styles are needed. Verify that the 44-pin PLCC footprint matches the target PCB layout constraints and that the operating temperature range aligns with the final application environment.
