Ensure that the ordering information matches the required package type and speed grade. Confirm that any requested revisions align with current manufacturing availability and lifecycle status before finalizing purchase orders.

Selection Notes

Select this device when high logic density and substantial embedded memory are required for complex FPGA designs. Evaluate the available I/O count and transceiver bandwidth against interface requirements. Consider thermal management solutions due to the power consumption characteristics of high-performance Stratix II devices. Verify that the chosen package option fits the mechanical constraints of the target PCB design.

Part Context

This component is part of the Stratix II product line, representing a generation of FPGAs designed for high-performance applications prior to the introduction of Stratix III and IV families. It serves as a legacy solution for existing designs requiring robust programmable logic capabilities. The device remains relevant for maintenance and upgrade cycles in established industrial and telecommunications hardware platforms.

Replacement Considerations

Direct pin-to-pin replacements may not be available due to architectural differences in newer generations. Upgrades typically require redesigning the board layout and updating the FPGA configuration files. Consult official migration guides from Intel for recommended alternatives such as Stratix III or IV devices, ensuring functional equivalence and interface compatibility.
