Cyclone IV E FPGA — 28848 LEs, 532 I/O, 780-BGA
It is a mid-density member of the Cyclone IV E family, sized for cost-sensitive applications that still need substantial logic and pin count — think motor-drive control logic, industrial Ethernet bridges, or multi-axis servo interfaces where a hard ARM core would be overkill and you want the deterministic timing of LUT-based logic. That covers most indoor industrial and telecom enclosures, but if the board sits in an unventilated cabinet near a hot motor drive, check the thermal profile — the 780-BGA (29x29 mm) has no heatsink pad on the bottom, so forced airflow or a thermal plane in the PCB stack-up may be needed.
For dual-sourcing resilience, the EP4CE40F29C8 is the closest density sibling in the same package and I/O count. It is a higher-density variant.
