Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC5512MV-75F484I is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 484-BBGA (23x23) package to ensure mechanical fit and PCB routing compatibility.

I/O Pin Count: The substitute must provide a minimum of 253 I/O pins to maintain signal connectivity in existing designs.

Programmable Architecture: The substitute must support In System Programmable (ISP) functionality to enable field programming and reconfiguration.

Voltage Supply Range: The substitute must operate within or encompass the 3V ~ 3.6V supply range to ensure compatibility with existing power distribution networks.

Operating Temperature Range: The substitute must support the full -40°C ~ 105°C operating temperature range for thermal compatibility.

Logic Capacity: The substitute must provide sufficient logic elements to accommodate designs originally targeting 512 macrocells.

The LCMXO2-2000UHC-4FG484I meets these substitution criteria through identical package geometry, expanded I/O capability (278 pins), ISP support, compatible voltage specifications, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LC5512MV-75F484I is classified as obsolete, while the LCMXO2-2000UHC-4FG484I maintains active product status with ongoing manufacturer support and availability.

Compliance Status: The LCMXO2-2000UHC-4FG484I is ROHS3 compliant, whereas the LC5512MV-75F484I is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the substitute provides superior environmental and regulatory alignment.

Voltage Supply Compatibility: The LCMXO2-2000UHC-4FG484I voltage range (2.375V ~ 3.465V) encompasses the LC5512MV-75F484I range (3V ~ 3.6V), ensuring direct compatibility with existing power supplies.

Package and Thermal Specifications: Both devices share identical 484-BBGA (23x23) package geometry and equivalent moisture sensitivity levels, enabling direct PCB substitution without layout modifications.

Operating Temperature Range: The LC5512MV-75F484I supports -40°C ~ 105°C, while the LCMXO2-2000UHC-4FG484I supports -40°C ~ 100°C. Applications requiring operation above 100°C require design review.

I/O Expansion: The LCMXO2-2000UHC-4FG484I provides 278 I/O pins compared to 253 on the original device, offering additional signal routing flexibility without package constraints.

Frequently Asked Questions (FAQ)

Q: Can the LCMXO2-2000UHC-4FG484I directly replace the LC5512MV-75F484I on existing PCBs?

A: Yes. Both devices use identical 484-BBGA (23x23) package geometry, enabling direct mechanical and electrical substitution without PCB redesign. Pin assignments must be verified against design documentation to ensure signal routing compatibility.

Q: What is the primary reason for substitution?

A: The LC5512MV-75F484I is obsolete. The LCMXO2-2000UHC-4FG484I is an active product from the same manufacturer, ensuring long-term availability, technical support, and compliance with current regulatory standards.

Q: Are there voltage supply differences that affect circuit design?

A: The LCMXO2-2000UHC-4FG484I operates at 2.375V ~ 3.465V, which overlaps and extends the LC5512MV-75F484I range of 3V ~ 3.6V. Existing 3.3V supply designs are fully compatible without modification.

Q: Does the operating temperature range differ?

A: The LC5512MV-75F484I supports -40°C ~ 105°C, while the LCMXO2-2000UHC-4FG484I supports -40°C ~ 100°C. Applications requiring operation above 100°C must evaluate thermal requirements against the substitute's maximum rating.

Q: What is the significance of the additional I/O pins on the substitute?

A: The LCMXO2-2000UHC-4FG484I provides 278 I/O pins versus 253 on the original device. Unused pins can remain unconnected without affecting device operation, providing design flexibility for future enhancements.

Q: Is RoHS compliance a factor in substitution?

A: The LCMXO2-2000UHC-4FG484I is ROHS3 compliant, while the LC5512MV-75F484I is not. For new designs or systems subject to environmental regulations, the substitute provides compliance alignment.

Q: Are both devices In System Programmable?

A: Yes. Both the LC5512MV-75F484I and LCMXO2-2000UHC-4FG484I support In System Programming, enabling field configuration and reconfiguration without device removal.

Q: What packaging considerations apply to both devices?

A: Both devices share MSL 3 (168 Hours) moisture sensitivity classification and identical 484-FPBGA/FBGA (23x23) package dimensions, ensuring equivalent handling, storage, and assembly requirements.
