Microcontrollers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm that the 'I' designation corresponds to the industrial temperature range requirements for your deployment environment. Ensure compatibility with the QFN-28 package dimensions during PCB layout planning.

Microcontrollers Selection Notes

Select this component for designs requiring low-voltage operation down to 2.0 V while maintaining standard PIC18 performance. Consider the QFN-28 package for space-constrained layouts. Evaluate the 5-channel ADC requirement against application needs, as other family members offer more channels.

Microcontrollers Part Context

This part belongs to the PIC18F2331/2431/4331/4431 family datasheet DS39616D. It is the low-voltage variant (LF) of the PIC18F2331. The 'T' suffix denotes tape and reel packaging, while 'MM' specifies the QFN-28 package type.

Microcontrollers Replacement Considerations

PIC18F2331T-I/MM serves as the standard voltage equivalent. PIC18LF2331-I/MM is the tube-packaged version of the same silicon.
