What this Cyclone IV E FPGA delivers
The Intel EP4CE55F23C9LN is a Cyclone® IV E FPGA in a 484-BGA package, offering 55856 logic elements and 324 user I/Os. It carries 2396160 bits of embedded block RAM, enough for moderate FIFO buffers or frame storage without external SRAM. The core supply runs at 0.97 V to 1.03 V — a tight window that demands a clean, low-noise regulator. Operating temperature is 0°C to 85°C, so this part is aimed at commercial indoor equipment: test gear, industrial controllers, communications infrastructure, and similar rack-mount or benchtop systems.
Logic density and memory — what fits
With 55856 logic elements and 3491 LABs/CLBs, this FPGA sits in the mid-range of the Cyclone IV E family. The 2396160 bits of RAM support moderate buffering and pipelining. Compared to the EP4CE40F29C8 (39600 LEs, 1161216 bits RAM), this part offers roughly 40% more logic and double the block RAM — a meaningful step up for designs that need extra combinatorial depth or larger FIFOs without migrating to a larger package.
I/O and package — board-level fit
The 324 I/Os are distributed across a 484-ball BGA (23×23 mm). The 0.97–1.03 V core rail is separate from the I/O banks.
Lifecycle and sourcing
This part carries an Active lifecycle status — no end-of-life notice, no last-time-buy window. It remains a current production device suitable for new designs and ongoing production. For dual-sourcing or supply resilience, the Cyclone 10 LP 10CL055YF484C6G offers the same logic density (55856 LEs), same RAM (2396160 bits), same I/O count (321), and the same 484-BGA footprint, though its core voltage is 1.2 V — a regulator change on the board. The EP4CE55F23C9LN is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time.
