What the 17K logic cells and 358 I/O mean for your design
The LFXP2-17E-5FN484I packs 17,000 logic cells (2125 LABs/CLBs) and 282,624 total RAM bits — enough for a modest soft-core processor, a few UART/SPI interfaces, and glue logic without reaching for a larger die. With 358 user I/O in the 484-ball FBGA package, you get plenty of headroom for a wide memory bus, parallel sensor array, or a bunch of peripheral pins — the limiting factor is more likely the board routing than the FPGA itself.
Industrial temperature grade and supply rail
Core supply is 1.14 V — a single 1.2 V rail with a small LDO drop works fine; the 1.14 V figure is the nominal, so a 1.2 V ±5% regulator keeps you inside the operating window.
Package and board-fit realities
The 484-ball FBGA (Fine-pitch Ball Grid Array) demands a multi-layer PCB — four layers minimum for fan-out, six if you want clean power distribution and signal integrity on the high-I/O banks. Supplied in tray format, not tape-and-reel — fine for prototyping or low-volume production; if you need reel for pick-and-place, check with your sourcing contact at quote time.
