Procurement Notes

Verify the component revision against the datasheet errata section prior to implementation. Confirm that the selected speed grade aligns with the required operating voltage range. Ensure programming tools support the specified SPI interface for in-system programming. Check for any known silicon revisions affecting EEPROM write operations or watchdog timer functionality.

Selection Notes

Select this model when a 20-pin through-hole package is required for prototyping or manufacturing. Choose the -20 suffix variant if operation at 20 MHz is necessary within the 2.7 V to 5.5 V supply range. Consider alternative packages like SOIC or QFN if board space constraints exist. Verify that the 18 available I/O lines meet the peripheral requirements of the target application.
