LC4032V-75T48I

Overview

The LC4032V-75T48I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 32 user I/Os 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 EEPROM non-volatile memory technology for configuration, allowing for in-system programmability. The component functions on a single 3.3 V supply voltage and is rated for commercial temperature ranges.

Feature Summary

• ispMACH 4000V architecture with 32 macrocells
• EEPROM-based non-volatile configuration
• In-system programmability via JTAG
• 400 MHz maximum operating frequency

Applications

• Interface bridging between different logic families
• Address decoding and control logic
• State machine implementation
• Bus protocol conversion

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range variant compared to the 'C' commercial grade. Confirm the package type is TQFP-48. Ensure the design tool suite supports the ispMACH 4000V family for programming and simulation.

Selection Notes

Select this model when 32 macrocells are sufficient for the logic density requirements. The 7.5 ns delay suits moderate-speed applications. Compare against the LC4032B series if higher speed or different pin counts are needed. Verify power consumption constraints align with the 3.3 V operation.

Part Context

This part belongs to the Lattice ispMACH 4000V family, which succeeded earlier ispMACH 4000 devices. The 'V' denotes the 4000V series enhancements over the original 4000 series. It serves as a drop-in replacement for legacy CPLDs in designs requiring non-volatile configuration without external flash memory.

Replacement Considerations

The LC4032V-75TN48C is a commercial grade equivalent with identical electrical specifications but a lower temperature rating. Cross-reference with the LC4032B-75T48I for potential performance differences in the older B-series architecture.
