Substitute Part Grouping Explanation

Substitution of the EP2S90F780C4 is determined by strict equivalence across the following critical parameters:

• Logic element count: 90,960 elements
• RAM capacity: 4,520,488 bits
• I/O pin count: 534 pins
• Supply voltage range: 1.15V ~ 1.25V
• Package type: 780-BBGA / 780-FBGA (29x29)
• Operating temperature range: 0°C ~ 85°C (TJ)
• Mounting configuration: Surface Mount

The EP2S90F780C5 qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status from Altera (now part of Intel).

Parameter Comparison

Engineering Selection Recommendations

The EP2S90F780C5 is the qualified substitute for the obsolete EP2S90F780C4. Both devices maintain identical electrical specifications, logic capacity, memory configuration, and thermal operating range. The primary distinction is product status: the EP2S90F780C5 is actively manufactured and supported, whereas the EP2S90F780C4 is obsolete.

Selection of the EP2S90F780C5 is appropriate for new designs and ongoing production requiring Stratix® II FPGA functionality at the 90,960 logic element density. Both parts share equivalent RoHS non-compliance status and REACH unaffected classification. Moisture sensitivity handling (MSL 3, 168 hours) applies uniformly to both variants.

Frequently Asked Questions (FAQ)

Q: Can the EP2S90F780C5 directly replace the EP2S90F780C4 in existing designs?

A: Yes. The EP2S90F780C5 maintains identical electrical and mechanical specifications, including logic element count, RAM capacity, I/O pin configuration, supply voltage, package dimensions, and operating temperature range. Pin-for-pin compatibility is assured.

Q: What is the primary reason for substitution?

A: The EP2S90F780C4 is classified as obsolete. The EP2S90F780C5 provides equivalent functionality with active product status and ongoing manufacturer support.

Q: Are there package differences between these parts?

A: Both parts use the 780-FBGA (29x29) supplier device package. The EP2S90F780C5 documentation references both 780-BBGA and FCBGA designations, but the physical package and pin configuration remain identical to the EP2S90F780C4.

Q: Do supply voltage and thermal requirements differ?

A: No. Both parts operate at 1.15V ~ 1.25V supply voltage and share the same operating temperature range of 0°C ~ 85°C (TJ).

Q: What is the moisture sensitivity consideration?

A: Both parts carry MSL 3 rating with a 168-hour floor life. Identical moisture handling and storage protocols apply to both variants.
