Logic capacity and I/O budget
The LFXP2-17E-6FTN256C packs 17000 logic cells (2125 LAB/CLB slices) and 282624 bits of embedded block RAM — enough for a moderate-size state machine, a small soft-core processor, or a glue-logic consolidation that would otherwise eat a dozen 44-pin PLDs.
Surface-mount only; the tray packaging suits both hand-assembly prototypes and reflow production runs.
Active lifecycle — sourcing posture
Lattice Semiconductor lists the LFXP2-17E-6FTN256C as Active.
Peer comparison — I/O count difference
The closest sibling, LFXP2-17E-5FN484I, shares the same 17000 logic cells and 282 Kbit RAM but offers 358 I/O in a 484-ball BGA — a 157-I/O increase over the 256-ball package. The 5FN484I also extends the temperature range to -40°C to 100°C. The two parts are not pin-compatible; a board designed for the 256-ball FTBGA cannot accept the 484-ball BGA without a layout change.
