Cyclone IV E FPGA — 15408 LEs, 165 I/O in 256-FBGA
It has 165 user I/O and 516096 total RAM bits.
The 15408 logic elements (963 LABs/CLBs) give you roughly 15K usable LUTs for combinatorial and registered logic. The Cyclone IV GX family carries 14400 LEs — the E variant trades the transceivers for more I/O (165 vs 72) and a different package footprint. The 516096 total RAM bits are organized as M9K blocks — enough for a moderate FIFO, a small frame buffer, or coefficient storage without external SRAM.
