The LFXP2-40E-5FN484C is a Lattice Semiconductor XP2-series FPGA delivering 40000 logic cells and 363 user I/O in a 484-ball FBGA package. On-chip block RAM totals 906240 bits, and the device is built around 5000 LUT-4-based logic slices (Labs/CLBs) — enough for moderate-complexity glue logic, bridge functions, or a soft-core MCU peripheral set.

The LFE3-35EA-6FN484C is a higher-density ECP3-series sibling with 33000 logic cells, 295 I/O, and 1358848 bits of block RAM. It is not pin-compatible — the 484FBGA footprint differs in ball assignment — so a board spin is required to swap. For a drop-in replacement within the same package, stay with the XP2 family; the LFXP2-40E-5FN484C is the largest I/O-count variant in that series.
