Cyclone IV E — 114k LE workhorse for mid-density logic
The Intel EP4CE115F29I8LN is a Cyclone IV E FPGA with 114480 logic elements and 3981312 RAM bits in a 780-ball FBGA (29x29 mm). It provides 528 user I/O.
Active lifecycle — no LTB clock ticking
Intel lists this device as Active. That means no last-time-buy notice, no end-of-life pressure on your supply chain. You can qualify it into a new design and expect multi-year availability through distribution and independent channels. The base product number EP4CE115 covers multiple speed and temperature grades, so if you ever need to flex to a commercial-temperature or faster-speed variant, the pinout stays the same.
780-FBGA footprint — board integration notes
The 780-FBGA (29x29 mm) is a standard high-density BGA. Route the core plane on an inner layer with sufficient copper pour.
