Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC4032V-10T44I is determined by strict equivalence across the following critical parameters:

• Macrocell Count: 32 macrocells (functional logic capacity)
• Logic Elements/Blocks: 2 blocks (architectural configuration)
• Propagation Delay: 10 ns maximum (timing performance)
• Supply Voltage: 3V ~ 3.6V (power compatibility)
• I/O Count: 30 I/O pins (interface capacity)
• Temperature Range: -40°C ~ 105°C (operational envelope)
• Package Type: 44-TQFP (physical form factor and pin count)
• Programmability: In System Programmable (design flexibility requirement)

The LC4032V-10TN44I meets all these criteria and qualifies as a direct substitute. The primary distinction between the main part and its substitute is product status and packaging configuration, not functional or electrical parameters.

Engineering Selection Recommendations

The LC4032V-10TN44I is the direct functional equivalent of the LC4032V-10T44I. Selection between these parts should be based on the following criteria:

For New Designs: The LC4032V-10TN44I is the appropriate choice. This part carries Active product status, ensuring long-term availability and manufacturer support. It meets ROHS3 compliance requirements, satisfying modern environmental and regulatory standards.

For Legacy System Maintenance: The LC4032V-10T44I remains electrically and functionally identical to its substitute. If existing inventory is available and regulatory compliance is not a constraint, this part maintains full compatibility with established designs.

Compliance Considerations: The LC4032V-10TN44I's ROHS3 compliance status provides regulatory alignment for applications subject to environmental directives. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the LC4032V-10TN44I directly replace the LC4032V-10T44I in existing designs?

A: Yes. Both parts are electrically and functionally identical across all critical parameters: macrocell count, logic blocks, propagation delay, supply voltage, I/O count, temperature range, and package configuration. No design modifications are required.

Q: What is the difference between the tube and tray packaging options?

A: Packaging format affects handling and storage but does not alter electrical or functional characteristics. Tube packaging (LC4032V-10T44I) and tray packaging (LC4032V-10TN44I) contain identical die and performance specifications. Selection depends on assembly process requirements and inventory management practices.

Q: Why is the LC4032V-10T44I marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The LC4032V-10TN44I, carrying Active status, represents the current production equivalent and is recommended for new designs to ensure supply chain continuity.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts specify identical maximum propagation delay of 10 ns and operate within the same voltage supply range of 3V to 3.6V. Functional performance is equivalent.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical characteristics. The ROHS3 compliance of the LC4032V-10TN44I does not alter its functional equivalence to the LC4032V-10T44I.
