LC4032V-5T44I

Overview

The LC4032V-5T44I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It integrates 32 macrocells and supports up to 30 I/O lines within a 44-pin TQFP package. The device operates with a 1.8 V core voltage for low dynamic power consumption while providing 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. Key electrical parameters include a maximum clock frequency of 156 MHz, a propagation delay (tpd) of 5 ns, and a typical standby current of 11.3 µA.

Feature Summary

• Integrates 32 macrocells with 5 V tolerant I/Os supporting LVCMOS 3.3, LVTTL, and PCI standards.
• Features JTAG In-System Programmability (ISP) for flexible design updates.
• Operates on a 1.8 V core voltage with a typical standby current of 11.3 µA.
• Delivers SuperFAST performance with a maximum frequency of 156 MHz.

Applications

• General-purpose logic replacement in industrial control systems.
• Interface bridging between 5 V and 3.3 V logic domains.
• Address decoding and bus buffering in embedded systems.
• State machine implementation in communication equipment.

Procurement Notes

Verify component authenticity as this specific part number may be discontinued or superseded by newer revisions within the ispMACH 4000V family. Confirm that the 44-TQFP (10x10 mm) package matches the target PCB footprint. Ensure the design accounts for the 1.8 V core supply requirement despite the 5 V tolerant I/O capabilities.

Selection Notes

Select this model when 32 macrocells are sufficient for the logic density requirements. Compare against the LC4032V-5FT256I if a BGA package is preferred for higher pin counts. Consider the LC4032ZE variant if automotive temperature range support (-40 to +130 °C junction temperature) is required for the application environment.

Part Context

This component belongs to the Lattice ispMACH 4000V series, which blends ispLSI 2000 and ispMACH 4A architectures. The 'V' suffix denotes the 3.3 V/1.8 V core voltage variant. The '5' indicates the speed grade, and 'T44' specifies the 44-pin Thin Quad Flat Package (TQFP) with a 1.0 mm pitch.

Replacement Considerations

Public confirmed substitute part numbers: LC4032V-5FT256I (BGA package), LC4032ZE-5T44I (Automotive grade).
