Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPF8282ATC100-2 is determined by the following critical parameters:

• Package Compatibility: 100-pin TQFP/LQFP form factor with 14x14mm footprint
• I/O Pin Count: 78 I/O pins minimum
• Logic Capacity: Minimum 208 logic elements to support equivalent functionality
• Supply Voltage: Operating voltage range must accommodate system requirements
• Mounting Type: Surface mount configuration
• Operating Temperature Range: Must support the application's thermal environment

The LCMXO256C-4TN100C from Lattice Semiconductor Corporation qualifies as a substitute based on matching package geometry, I/O count, logic element capacity, and surface mount characteristics. This device maintains functional equivalence while offering enhanced specifications in certain parameters.

Parameter Comparison

Engineering Selection Recommendations

The LCMXO256C-4TN100C is an active product with current manufacturing support and ROHS3 compliance, addressing the obsolescence status of the EPF8282ATC100-2. The substitute maintains identical I/O pin count and footprint dimensions, ensuring mechanical and electrical compatibility at the board level.

The substitute device provides 256 logic elements compared to the original 208, offering additional design margin. Operating temperature range extends to 85°C, supporting broader thermal environments. Supply voltage operates at 1.71V to 3.465V, which differs from the original 4.75V to 5.25V specification and requires voltage regulation verification in the target application.

Both devices share identical MSL ratings and ECCN/HTSUS classifications. The substitute's active product status ensures long-term availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can the LCMXO256C-4TN100C directly replace the EPF8282ATC100-2 without PCB modifications?

A: The 100-pin TQFP and 100-pin LQFP packages share identical 14x14mm footprints and pin pitch. Direct PCB-level substitution is possible without layout changes. However, supply voltage requirements differ significantly and must be addressed through power delivery circuit modifications.

Q: What is the primary difference in supply voltage between these devices?

A: The EPF8282ATC100-2 requires 4.75V to 5.25V (5V nominal), while the LCMXO256C-4TN100C operates at 1.71V to 3.465V (3.3V nominal). System power architecture must be evaluated to accommodate the lower voltage requirement of the substitute.

Q: Are the I/O pin assignments identical between these parts?

A: Both devices feature 78 I/O pins in the same 100-pin package. Pin-to-pin compatibility at the package level is maintained. Design verification is required to confirm functional equivalence for specific application requirements.

Q: Does the LCMXO256C-4TN100C support the same operating temperature range?

A: The substitute supports 0°C to 85°C (TJ), which exceeds the original 0°C to 70°C (TA) specification. This provides enhanced thermal margin for applications operating in elevated temperature environments.

Q: What is the significance of the active product status for the substitute?

A: Active product status indicates current manufacturing, ongoing technical support, and long-term availability. This addresses the obsolescence constraint of the original EPF8282ATC100-2 and ensures supply chain continuity.

Q: Are both devices RoHS compliant?

A: The EPF8282ATC100-2 is RoHS non-compliant. The LCMXO256C-4TN100C is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and manufacturing environments.
