Cyclone IV E FPGA — 55856 logic elements in a 484-ball BGA
The Intel Cyclone IV E EP4CE55U19I7N is a mid-density FPGA in the Cyclone IV E family, packing 55856 logic elements and 2396160 total RAM bits into a 484-UBGA (19x19) package. The 324 user I/Os give enough headroom for parallel memory interfaces, camera links, or a bank of LVDS pairs — typical for motor-drive control, industrial vision, and communications bridging where you need moderate gate count without stepping to a larger BGA.
What the I/O count and RAM mean for the BOM
The 2396160 total RAM bits are distributed across M9K blocks. That is enough for moderate-sized FIFOs, line buffers for a VGA-resolution image sensor, or coefficient storage for a FIR filter.
That means it is still a valid selection for new designs and standard-channel procurement — no NRND or last-time-buy clock ticking. The base product number EP4CE55 covers multiple speed and temperature grades; the 'I7' suffix denotes the industrial temperature range and the fastest speed grade available in this density.
