Logic capacity and I/O count for BOM fit
The EP4CE115F29C7: With 528 user I/O in a 780-BGA package (29x29 mm FBGA), the pin density supports wide parallel buses or a high count of discrete interfaces, but the 0°C~85°C commercial temperature grade restricts deployment to controlled indoor environments, not extended or industrial ranges.
On-chip memory and supply rail planning
3981312 total RAM bits (roughly 4 Mbit) provide on-chip buffer headroom for FIFOs, line buffers, or small packet stores — enough for a 1080p video line buffer at 8-bit depth, but insufficient for full-frame storage without external SDRAM. The core supply range is 1.15V to 1.25V — the regulator output must stay within this window under load transients; a 1.2V nominal rail with ±3% tolerance covers it, but a 1.1V fixed-output LDO does not.
Active lifecycle and sourcing posture
Listed as Active — no last-time-buy pressure for existing designs, and the Cyclone IV E family remains a supported Intel FPGA tier for cost-sensitive, high-I/O applications where the 28-nm low-power process is sufficient.
