Procurement Notes

Verify component authenticity and datasheet revisions prior to procurement. Confirm package integrity and pin compatibility during integration. Check for RoHS compliance status as this legacy item may not meet current environmental standards. Ensure supply chain stability due to potential discontinuation or limited availability from original manufacturers.

Selection Notes

Select this component when a specific 32-bit i960 core is required for backward compatibility or legacy system maintenance. Consider the 132-PQFP package constraints for board layout. Evaluate thermal management requirements given the 100°C junction temperature limit. Assess if the 25MHz performance meets application timing needs compared to modern alternatives.

Part Context

This microprocessor belongs to the Altera i960 family, which was widely used in networking and industrial applications before being superseded by newer architectures. Altera's acquisition by Intel integrated these legacy processors into broader embedded portfolios. The TG suffix typically denotes specific packaging and temperature grade variations within the i960 product line.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific legacy variant. Engineers should evaluate modern 32-bit ARM or RISC-V cores for new designs, ensuring software compatibility migration strategies are in place for existing i960 codebases.
