Overview
Cyclone IV E is the low-power, transceiver-free branch of the Cyclone IV family. The EP4CE115 offers 114,480 logic elements, 3,888 Kb of M9K memory and 266 embedded 18 × 18 multipliers on a 60 nm low-power process, with four PLLs and up to 528 user I/O.
It remains one of the most widely deployed low-cost FPGAs in industrial equipment, and it is still actively supplied because a very large installed base of machines depends on it. The EP4CE115 sits at the top of the family's density range and is usually the part sourced for board respins and spares.
Key Benefits
Very large installed base with long-term supply for machine retrofits and spares. 266 hardware multipliers deliver real DSP throughput at low cost. Up to 528 user I/O on the F1152 package for multi-channel video and I/O-heavy boards.
Applications
Industrial automation controllers, multi-channel video and LCD switching, broadcast glue logic, motor and drive control, medical instrumentation, and legacy Cyclone-family board maintenance.
