Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPF10K10ATC100-1 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use a 100-pin TQFP/VQFP package format (14x14mm) to ensure PCB footprint compatibility and pin assignment alignment.

I/O Pin Count: The substitute must provide a minimum of 66 I/O pins to maintain signal routing capability. The XC3S50A-4VQG100C provides 68 I/O pins, meeting this requirement.

Logic Capacity: The substitute must provide sufficient logic elements to accommodate the original design. The EPF10K10ATC100-1 contains 576 logic elements; the XC3S50A-4VQG100C provides 1584 logic elements, offering increased capacity.

Memory Resources: The substitute must provide adequate embedded RAM. The EPF10K10ATC100-1 contains 6144 RAM bits; the XC3S50A-4VQG100C provides 55,296 RAM bits, exceeding the original specification.

Mounting Type: Both parts use surface mount technology, ensuring assembly process compatibility.

Moisture Sensitivity: Both parts share MSL 3 classification, requiring identical handling and storage protocols.

Parameter Comparison

Engineering Selection Recommendations

The XC3S50A-4VQG100C serves as a functional substitute for the obsolete EPF10K10ATC100-1 based on the following engineering criteria:

Package Compatibility: Both devices use 100-pin TQFP/VQFP packages with identical 14x14mm footprints, enabling direct PCB layout compatibility without redesign.

I/O Capacity: The XC3S50A-4VQG100C provides 68 I/O pins compared to the original 66 pins, maintaining signal routing capability with additional I/O availability.

Logic Resources: The substitute provides 1584 logic elements versus the original 576, offering 2.75x greater logic capacity for design flexibility and future enhancements.

Memory Resources: The XC3S50A-4VQG100C provides 55,296 RAM bits compared to 6144 bits in the original, delivering 9x greater embedded memory capacity.

Moisture Sensitivity: Both parts share MSL 3 classification, requiring identical handling protocols during storage and assembly.

Product Status Consideration: The EPF10K10ATC100-1 is obsolete, while the XC3S50A-4VQG100C is Last Time Buy status, providing a defined procurement window for design transitions.

Compliance: The XC3S50A-4VQG100C is RoHS3 compliant, meeting current environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the XC3S50A-4VQG100C directly replace the EPF10K10ATC100-1 without PCB modifications?

A: The 100-pin TQFP and 100-pin VQFP packages share identical 14x14mm footprints and pin spacing, enabling direct PCB compatibility. However, design implementation differences between FLEX-10KA® and Spartan®-3A architectures require HDL code adaptation and re-compilation.

Q: What are the key differences in electrical specifications between these parts?

A: The primary difference is supply voltage: the EPF10K10ATC100-1 operates at 3V–3.6V, while the XC3S50A-4VQG100C operates at 1.14V–1.26V. This requires separate power supply design and may necessitate level-shifting circuitry for I/O interfacing with 3.3V logic.

Q: Does the increased logic capacity of the XC3S50A-4VQG100C affect compatibility?

A: Increased logic elements (1584 vs. 576) and RAM bits (55,296 vs. 6144) provide design headroom but do not affect pin-level compatibility. The substitute can accommodate the original design with additional resources available for future expansion.

Q: Are there any moisture sensitivity or handling differences?

A: Both parts share MSL 3 classification (168 hours), requiring identical moisture control protocols during storage, handling, and assembly. No additional precautions are necessary.

Q: What is the significance of the product status difference?

A: The EPF10K10ATC100-1 is obsolete and no longer manufactured. The XC3S50A-4VQG100C is Last Time Buy status, indicating a defined procurement window before discontinuation. Long-term availability planning is recommended.
