Microcontrollers Procurement Notes

Verify that the ordering suffix 'SO' corresponds to the 28-pin Small Outline Integrated Circuit (SOIC) package type. Confirm the '-E' designation indicates the Extended temperature range (-40°C to +125°C). Ensure the specific revision matches the required datasheet version DS40002338B or later for accurate electrical specifications.

Microcontrollers Selection Notes

Select this component when 14 KB of program memory and 1 KB of RAM are sufficient for the application logic. The 28-pin SOIC package is suitable for surface-mount designs requiring moderate I/O density. Consider the extended temperature rating if the operating environment exceeds standard industrial limits.

Microcontrollers Part Context
