Active lifecycle — no LTB clock ticking
The EP4CE15F23C7N: The Cyclone IV E family is a mature, low-power mainstream FPGA line. Intel continues to support it alongside the newer Cyclone V and Cyclone 10 families, so the supply outlook is stable for ongoing production runs.
Logic density and I/O — what 15,408 LEs gets you
15,408 logic elements (963 LABs) place this device between the 10,320-LE EP4CE10 and the 22,320-LE EP4CE22 in the Cyclone IV E lineup. It is a mid-density part suited for glue logic, motor control state machines, sensor fusion, or moderate-throughput video bridging. 343 user I/O in a 484-ball BGA gives exceptional pinout flexibility for a device of this logic count — the I/O-to-LE ratio is high enough to route a wide parallel bus alongside dozens of discrete control signals without starving the core.
Memory and supply — on-chip RAM and voltage rail
516,096 total RAM bits (M9K blocks) provide 64 Kbytes of embedded memory for FIFOs, coefficient tables, or small frame buffers. For designs that need more than this, external SRAM or SDRAM is the next step. No negative rail or sequencing complexity beyond standard FPGA power-up.
This is the commercial grade — the part is not qualified for -40 °C cold start or extended industrial ambient. If the end equipment sees outdoor winter storage or an unheated enclosure, the industrial-temperature variant (I suffix) is the correct choice.
