Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFXP20C-3FN484C is determined by the following critical parameters:

• Package compatibility: 484-BBGA form factor with identical 23x23mm footprint
• I/O pin count: Minimum 340 I/O pins required for pinout compatibility
• Logic element capacity: Minimum 20,000 logic elements to support design complexity
• RAM capacity: Minimum 405,504 total RAM bits for memory requirements
• Operating temperature range: 0°C ~ 85°C (TJ) compatibility
• Surface mount capability for PCB assembly compatibility

The LFXP2-30E-5FN484C qualifies as a direct substitute based on these parameters. This XP2 series device maintains the identical 484-BBGA package, exceeds the minimum I/O count (363 I/O), provides greater logic element capacity (29,000 elements), and maintains compatible operating temperature specifications.
