LC4032V-5TN44C

Overview

The LC4032V-5TN44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It integrates 32 macrocells and 36 logic blocks within a 44-pin TQFP package, providing 30 user I/O pins. The device supports In-System Programming (ISP) via JTAG and utilizes non-volatile EEPROM technology for configuration storage. It operates on a supply voltage range of 3.0 V to 3.6 V with a maximum propagation delay of 5 ns. The component is designed for industrial temperature ranges and features 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces.

Feature Summary

• 32 Macrocells and 36 Logic Blocks
• In-System Programmability (ISP) via JTAG
• Non-Volatile EEPROM Configuration Memory
• 5 V Tolerant I/Os

Applications

• General-purpose digital logic replacement
• Bus bridging and protocol conversion
• Address decoding and control logic

Procurement Notes

Verify the specific suffix '5T' against official Lattice documentation to confirm the exact speed grade and temperature rating. Confirm package availability as distribution channels may vary. Check for end-of-life status or obsolescence notices directly from the manufacturer before procurement planning.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. Ensure the system power budget accommodates the 3.0 V to 3.6 V operating range. Verify that the 44-pin TQFP footprint fits the PCB layout constraints compared to BGA alternatives in the same family.

Part Context

This part belongs to the ispMACH 4000V series, which blends ispLSI 2000 and ispMACH 4A architectures. It offers SuperFAST performance with low power consumption, featuring a 1.8 V core voltage while maintaining 5 V tolerant I/Os for broader interface compatibility.

Replacement Considerations

Compatible variants within the same density include the LC4032V-5T44I for industrial temperature grades. Higher density options in the family include the LC4064V series.
