LC4032V-5T48I

Overview

The LC4032V-5T48I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It integrates 32 macrocells and supports up to 32 I/Os in a TQFP-48 package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes a 3.3 V core voltage for low dynamic power consumption while providing 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. The component features JTAG In-System Programmability and is rated for industrial temperature ranges.

Feature Summary

• ispMACH 4000V architecture with 32 macrocells and Global Routing Pool
• SuperFAST performance reaching 400 MHz with 7.5 ns max propagation delay
• 5 V tolerant I/Os supporting LVCMOS 3.3, LVTTL, and PCI standards
• JTAG In-System Programmability (ISP) for flexible configuration

Applications

• General-purpose logic replacement for legacy PLDs
• Interface bridging between 3.3 V and 5 V logic domains
• Control logic for embedded systems requiring non-volatile configuration

Procurement Notes

Verify the specific suffix 'I' indicates the Industrial temperature grade (-40°C to +85°C) as per Lattice naming conventions. Confirm package availability in TQFP-48. Check RoHS compliance status on the latest datasheet revision. Ensure ESD handling procedures are followed during assembly due to CMOS technology sensitivity.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic density. Choose the -5 speed grade if timing requirements exceed 7.5 ns propagation delay. Consider the -75 variant if faster switching speeds are necessary. Verify that the target system supports 3.3 V core voltage and requires 5 V tolerant inputs for interfacing.

Part Context

This part belongs to the ispMACH 4000V family, which blends ispLSI 2000 and ispMACH 4A architectures. The family offers high density and performance with low power consumption. Other members include LC4064V, LC4128V, and LC4256V, scaling up to 512 macrocells while maintaining similar interface and programming features.

Replacement Considerations

Direct pin-compatible replacements within the same family include LC4032V-75TN48C for faster speed grades. Cross-family migration to ispMACH 4000Z may offer enhanced features but requires schematic review. Legacy GAL devices can be replaced by verifying logic equivalence and timing constraints.
