Substitute Part Grouping Explanation

Substitute parts for the EPF8282ATC100-3 are identified based on the following critical parameters that determine functional and physical compatibility:

Primary Matching Criteria:

• Number of I/O pins: 78 (exact match required for pinout compatibility)
• Package type: 100-TQFP / 100-LQFP (same physical footprint and pin count)
• Mounting type: Surface Mount (consistent assembly process)
• Supplier device package: 100-TQFP (14x14) physical dimensions

Secondary Compatibility Parameters:

• Logic element count: Minimum 208 (equal or greater capacity acceptable)
• Supply voltage range: Must support operational requirements of target application
• Operating temperature range: Must encompass or exceed 0°C ~ 70°C minimum
• ECCN and HTSUS classifications: Maintained for regulatory consistency

The LCMXO256C-4TN100C meets these substitution criteria with 256 logic elements (exceeding the 208 minimum), identical 78 I/O pin count, and compatible 100-LQFP package in 14x14 dimensions.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EPF8282ATC100-3 is obsolete, while the LCMXO256C-4TN100C is active. Selection of the active substitute part ensures ongoing availability, manufacturer support, and access to updated documentation and technical resources.

Compliance and Certification: The LCMXO256C-4TN100C holds ROHS3 compliance, whereas the EPF8282ATC100-3 is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the substitute part provides regulatory alignment. Both parts maintain identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent export and trade compliance.

Physical and Electrical Compatibility: Both parts feature 78 I/O pins in 100-pin packages with identical physical dimensions (14x14 mm). The LCMXO256C-4TN100C provides 256 logic elements compared to 208 in the original part, offering increased design capacity without footprint changes. The substitute operates at a lower supply voltage range (1.71V ~ 3.465V versus 4.75V ~ 5.25V), requiring voltage regulation adjustments in the target application. The operating temperature range of the substitute (0°C ~ 85°C) exceeds the original specification (0°C ~ 70°C).

Frequently Asked Questions (FAQ)

Q: Can the LCMXO256C-4TN100C directly replace the EPF8282ATC100-3 without PCB modifications?

A: Physical pin count and package dimensions are identical (78 I/O, 100-TQFP/LQFP, 14x14 mm), allowing direct footprint compatibility. However, the supply voltage requirement differs significantly (1.71V ~ 3.465V versus 4.75V ~ 5.25V), necessitating power supply circuit modifications. Firmware or HDL code may require validation due to architectural differences between FLEX 8000 and MachXO series.

Q: What are the key differences in logic capacity between these parts?

A: The LCMXO256C-4TN100C provides 256 logic elements compared to 208 in the EPF8282ATC100-3, representing a 23% increase in available logic resources. This additional capacity does not affect pin count or package size, making it suitable for designs requiring expanded functionality within the same physical constraints.

Q: Are there voltage compatibility concerns when substituting?

A: Yes. The original part operates at 4.75V ~ 5.25V (5V logic), while the substitute requires 1.71V ~ 3.465V (low-voltage logic). Applications must implement appropriate voltage regulation and level-shifting circuits if interfacing with 5V logic domains. This is a critical design consideration and not a transparent substitution.

Q: How do the operating temperature ranges compare?

A: The LCMXO256C-4TN100C supports 0°C ~ 85°C (TJ), exceeding the EPF8282ATC100-3 specification of 0°C ~ 70°C (TA). The substitute part provides a wider thermal operating window, beneficial for applications in elevated temperature environments.

Q: What is the significance of the RoHS compliance difference?

A: The EPF8282ATC100-3 is RoHS non-compliant, while the LCMXO256C-4TN100C is ROHS3 compliant. For applications subject to RoHS directives or customer requirements mandating lead-free components, the substitute part satisfies regulatory and procurement specifications. Both parts maintain identical moisture sensitivity levels (MSL 3, 168 Hours).

Q: Are both parts classified under the same export control and tariff codes?

A: Yes. Both the EPF8282ATC100-3 and LCMXO256C-4TN100C share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent export compliance and tariff treatment in international trade scenarios.
