Procurement Notes

Verify the specific suffix codes against official Intel (formerly Altera) documentation to ensure correct temperature range and package variant. Confirm that the component matches the required pinout and electrical specifications for your design. Cross-reference the date code and lot number if traceability is required. Ensure compliance with RoHS directives applicable to the manufacturing batch.

Selection Notes

Choose this component when high logic density and integrated transceivers are required for networking or DSP tasks. Evaluate the power consumption profile against thermal constraints in the target enclosure. Consider the availability of development tools and IP cores compatible with the Stratix II family. Assess the need for specific I/O standards supported by the device pins.

Part Context

This part belongs to the Stratix II family, representing a generation of FPGAs designed for mid-to-high performance applications. It bridges the gap between lower-density devices and the larger Stratix III series. The family introduced enhanced transceiver technology and improved DSP capabilities compared to previous generations.

Replacement Considerations

Direct replacements within the same family include other 1SX280 variants with different package or speed grades. Upgrades may involve Stratix III or IV devices for increased capacity. Verify pin compatibility and software toolchain support before substituting.
