EP1S40F780C8N

Overview

The Altera EP1S40F780C8N is a Stratix I field-programmable gate array (FPGA) designed for high-performance digital logic applications. It features 39,600 logic elements and 2,375 LABs/CLBs within its fabric. The device integrates 2,322,432 total RAM bits for data storage and processing tasks. It supports up to 429 input/output terminals, facilitating extensive external connectivity. Operating at supply voltages between 1.15V and 1.25V, the component functions reliably within a junction temperature range of 0°C to 85°C. It is housed in a 780-ball FBGA package measuring 29x29 mm.

Procurement Notes

Verify the specific suffix 'C8N' against official Intel/Altera documentation to confirm voltage grade and environmental rating. Confirm current availability status as older Stratix families may have limited stock or end-of-life implications. Ensure compatibility with legacy programming tools if integrating into existing design flows.

Selection Notes

Select this component when Stratix I performance levels are required rather than newer Cyclone or Arria series. Evaluate the 780-ball FBGA footprint constraints during PCB layout. Compare power consumption profiles against alternative FPGAs if thermal management is a critical design constraint for the target application environment.

Part Context

This part belongs to the Stratix I family, representing an earlier generation of Altera's high-end FPGA portfolio. It serves as a predecessor to subsequent Stratix generations, offering distinct architectural characteristics suited for specific legacy or cost-sensitive high-performance designs compared to modern Agilex or Stratix 10 devices.

Replacement Considerations

Direct pin-to-pin replacements are generally unavailable due to architectural differences. Consider migrating to Stratix IV, V, or 10 series for enhanced performance, though redesign efforts will be necessary. Verify software toolchain support for legacy devices if maintaining backward compatibility.
