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.","metaTitle":"Intel Cyclone IV E EP4CE55F23C9LN FPGA, 55856 LEs, 324 I/O","metaDescription":"Intel Cyclone IV E EP4CE55F23C9LN FPGA with 55856 logic elements, 324 I/O, 2396160 bits RAM. 0.97–1.03V core, 0–85°C.

The part is fully RoHS compliant."},{"question":"What is the difference between EP4CE55F23C9LN and EP4CE55F23C8LN?","answer":"The difference is the speed grade: the 'C9' variant (this part) is the standard-speed grade, while the 'C8' variant is a faster speed grade. Both share the same logic density, I/O count, and package. The C8 part will achieve higher fMAX in timing-critical paths, but the C9 part is sufficient for many designs and typically carries a lower cost."},{"question":"Where can I buy EP4CE55F23C9LN?","answer":"This part is sourced and quoted to order through independent distribution.
