22320 logic elements in a 256-FBGA — what that means for the board
The Intel EP4CE22F17C7 is a Cyclone IV E FPGA with 22320 logic elements and 153 user I/O in a 256-FBGA package (17x17 mm). Total RAM bits are 608256, distributed across the embedded memory blocks. That is enough for a few small FIFOs or coefficient tables, but not for a frame buffer or large packet queue — plan external SRAM or SDRAM if the design needs more than a few hundred kilobits of on-chip storage.
Active lifecycle — no LTB pressure
The EP4CE22F17C7 carries an Active product status. No last-time-buy notice, no end-of-life window on the horizon. That makes it a safe choice for a production BOM that needs to run for another few years without a requalification event. The base product number is EP4CE22, which covers the 22K LE density tier across multiple speed grades and temperature options. If the design later needs a faster speed grade or industrial temperature, the same base number with a different suffix keeps the pinout and footprint identical — no board spin required.
