LC4032V-10TN44I

Overview

The Lattice LC4032V-10TN44I is a complex programmable logic device (CPLD) belonging to the ispMACH 4000ZE family. It features 32 macrocells and supports up to 44 I/O pins within a TQFP-44 package. The device operates at supply voltages of 1.8 V or 3.3 V, with a maximum operating frequency of 250 MHz and a typical propagation delay of 5 ns. Designed for industrial environments, it functions across a temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile configuration memory (NVCM) eliminates external configuration components.
• In-system programmability via JTAG interface for flexible design updates.
• High-density architecture with 32 macrocells and 44 I/Os in a compact TQFP-44 package.

Applications

• Interface bridging between legacy systems and modern digital protocols.
• Address decoding and control logic in embedded systems.
• State machine implementation for industrial automation controllers.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the '-10' speed grade corresponds to the 5 ns propagation delay specification. Ensure the TQFP-44 package matches the required footprint for PCB layout compatibility.

Selection Notes

Select this model when non-volatile storage is required to retain configuration without external flash memory. Compare against the LC4032Z variant if lower voltage operation or different thermal characteristics are needed. Verify that 32 macrocells provide sufficient logic resources for the target state machine complexity.

Part Context

This component is part of the Lattice ispMACH 4000ZE series, which integrates high-performance CPLD logic with on-chip non-volatile memory. This series is designed to replace discrete logic gates and simple PLDs in applications requiring reprogrammability and reduced board space.

Replacement Considerations

Direct functional equivalents within the same density include other variants from the LC4032V/Z family with compatible pinouts. Cross-referencing with the LC4000ZE datasheet is necessary to confirm electrical parameter alignment before substitution.
