With 179 user I/O and 645 LABs/CLBs, it fits mid-density glue logic, motor drive control bridges, and display interface aggregation where a separate MCU plus CPLD would eat board area.
The logic density sits between the Cyclone IV E 6K-class (6272 LEs in the EP4CE6F17C8N) and the 22K-class. For a design currently mapped to a 6K part that is running out of routing headroom, this is the natural step-up in the same 256-FBGA footprint — no board respin needed. The 423936 bits of block RAM handle moderate FIFO depths or small frame buffers without external SRAM.
Package and supply constraints
The 256-FBGA (17x17 mm) requires a multi-layer PCB. I/O banks can be configured for 3.3 V operation by setting VCCIO.
