Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC5512MB-75FN256C is determined by the following critical parameters:

• Package Compatibility: Both devices must use 256-pin BGA packaging (256-FPBGA/256-FTBGA, 17x17 form factor) to ensure PCB footprint compatibility
• I/O Count: The substitute must provide sufficient I/O pins to match or exceed the 193 I/O of the original device
• Programmable Architecture: Both devices must support in-system programmability to maintain design flexibility
• Voltage Supply Range: Operating voltage must be compatible with system power distribution
• Operating Temperature Range: The substitute must support the required thermal operating window
• Manufacturer Continuity: Lattice Semiconductor Corporation maintains design tool compatibility and technical support across product families

The LCMXO2-1200UHC-4FTG256I meets these substitution criteria as a functionally equivalent alternative from the same manufacturer.

• Regulatory Compliance: Both devices maintain REACH Unaffected status and identical MSL ratings, ensuring equivalent handling and storage requirements
• Manufacturer Support: Lattice Semiconductor Corporation provides design migration resources and tool compatibility between ispXPLD® 5000MB and MachXO2 product families
• Enhanced Capabilities: The substitute offers extended operating temperature range (-40°C to 100°C) and increased I/O count (206 vs. 193), providing design margin for future applications

Frequently Asked Questions (FAQ)

Q: Can the LCMXO2-1200UHC-4FTG256I be used as a direct replacement without PCB modification?

A: Yes. Both devices use identical 256-pin BGA packaging (17x17 form factor), enabling direct footprint compatibility. No PCB layout changes are required.

Q: What are the key differences in electrical specifications?

A: The substitute supports a wider voltage supply range (2.375V ~ 3.465V vs. 2.3V ~ 2.7V) and extended operating temperature range (-40°C ~ 100°C vs. 0°C ~ 90°C). Verify that your system power supply output falls within the substitute's voltage specification.

Q: Are design files and programming tools compatible between these devices?

A: Both devices are Lattice Semiconductor products supporting in-system programmability. Design migration typically requires tool updates and design file recompilation. Consult Lattice technical documentation for specific migration procedures.

Q: Does the substitute provide equivalent logic capacity?

A: The LCMXO2-1200UHC-4FTG256I provides 1280 logic elements and 75776 RAM bits, compared to the LC5512MB-75FN256C's 512 macrocells. The substitute offers enhanced logic capacity and on-chip memory resources.

Q: Are moisture sensitivity and handling requirements identical?

A: Yes. Both devices carry MSL rating 3 (168 Hours), requiring identical storage, handling, and reflow procedures.

Q: What is the supply availability status?

A: The LC5512MB-75FN256C is obsolete with limited remaining inventory. The LCMXO2-1200UHC-4FTG256I is in active production with established supply availability.
