Logic density and I/O for mid-density co-processing
The LFE2-20E-6FN484I packs 21,000 logic elements and 331 user I/O in a 484-ball FBGA — enough fabric to handle a modest soft-core processor, a video scaler, or a multi-channel serial bridge without bumping to a larger device.
The core supply is 1.14 V — a single 1.2 V rail with a small LDO drop is typical; the 1.14 V minimum means the regulator must hold regulation under load transients.
On-chip block RAM and package format
282,624 total RAM bits are distributed as ECP2 block RAMs — enough for a 256×32 FIFO, a small lookup table, or a coefficient store for a digital filter. The 484-ball FBGA is a 1.0 mm pitch package; the inner rows need micro-vias or blind vias on a 6+ layer board, so budget PCB stack-up accordingly. Supplied in tray.
