The Altera EP2S180F1508C5 is a Stratix® II FPGA with 179400 logic elements, 1170 I/O pins, and 9383040 total RAM bits, packaged in a 1508-FBGA for surface-mount assembly. This is a high-density device aimed at communications infrastructure, high-end signal processing, and ASIC prototyping—any application where the logic count and I/O bandwidth of a smaller Cyclone series device would run out of headroom.
Logic density and memory — sizing the resource budget
With 179400 logic elements, the EP2S180F1508C5 has more than double the logic count of the EP4CE75F23C7N (75408 LEs). The 9383040 total RAM bits provide on-chip storage for deep packet buffers or DSP coefficient tables, reducing external SRAM count in a datapath design.
I/O and package — what the 1508-FBGA means for layout
The 1170 I/O pins on a 1508-ball FBGA require a multi-layer PCB with fine-pitch routing.
