What this Cyclone IV E FPGA brings to the board
The Intel EP4CE6E22C7 is a Cyclone® IV E FPGA with 6272 logic elements and 91 user I/O pins in a 144-EQFP package with an exposed pad. It carries 276480 bits of embedded RAM, organized as 392 LABs/CLBs.
6272 logic elements — what that means for your design
With 6272 logic elements, this part sits in the entry-to-mid tier of the Cyclone IV E family. It is sized for designs that need a few hundred flip-flops and some combinatorial logic.
Package and footprint: 144-EQFP with exposed pad
The 144-EQFP (20x20 mm) with an exposed pad requires a thermal land on the PCB. The exposed pad must be soldered to a ground plane for both thermal relief and electrical grounding — a cold joint here can cause intermittent failures under load. The 91 I/O are distributed around the four sides; verify your pin assignment against the Intel pinout file before committing the layout. The package is surface-mount, tray-shipped.
