LC4032V-75TN48I

Overview

The LC4032V-75TN48I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 32 user I/O pins within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes an in-system programmable EEPROM technology for non-volatile configuration, allowing for repeated reprogramming without removal from the circuit board.

Feature Summary

• 32 Macrocells with 32 User I/Os
• In-System Programmability via EEPROM
• 400 MHz Maximum Operating Frequency
• 7.5 ns Typical Propagation Delay

Applications

• High-density logic replacement
• Bus protocol conversion
• Address decoding and control logic

Procurement Notes

Verify the specific suffix 'I' against the datasheet to confirm the industrial temperature range (-40°C to +85°C). Confirm the package type is TQFP-48. Ensure compatibility with existing programming tools such as ispVM System software for configuration.

Selection Notes

Select this component when 32 macrocells are sufficient for the design complexity. Compare against the LC4032V-75TN48C if commercial temperature range (0°C to +70°C) is adequate, potentially offering different availability or cost structures. Verify voltage levels match the 3.3V supply requirement.

Part Context

This part belongs to the ispMACH 4000V family, designed for high-performance applications requiring low power consumption and small form factors. It serves as a successor to earlier ispMACH devices, offering improved speed and density while maintaining backward compatibility with legacy designs.

Replacement Considerations

Direct pin-compatible replacements within the same family include LC4032V-75TN48C (commercial grade). Cross-family replacements may require schematic review due to differences in I/O characteristics and power requirements.
