LC4032ZE-7MN64C

Overview

The LC4032ZE-7MN64C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000ZE family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 28 I/Os within a TQFP-48 package. The device operates at a supply voltage of 1.8V with a maximum propagation delay of 5.8ns and a maximum operating frequency of 260MHz. Designed for low power applications, it includes in-system programmability via IEEE 1532 and offers enhanced I/O flexibility.

Feature Summary

• ispMACH 4000ZE architecture with 32 macrocells and 4 Logic Array Blocks (LABs)
• Maximum operating frequency of 260 MHz with 5.8 ns typical propagation delay
• Supports 1.8V core voltage with 3.3V, 2.5V, 1.8V, and 1.5V I/O interface compatibility
• In-system programmability using IEEE 1532 standard

Applications

• High-speed interface bridging
• Address/data bus decoding
• Logic replacement for legacy discrete components

Procurement Notes

Verify component status as the LC4032ZE series may be subject to lifecycle changes such as NRND (Not Recommended for New Designs). Confirm package availability in TQFP-48 and ensure compliance with RoHS directives. Check for moisture sensitivity levels and storage conditions prior to assembly.

Selection Notes

Select this model for designs requiring moderate logic density with high speed and low power consumption. Ensure the design fits within 32 macrocells and 28 I/O constraints. Verify that the 1.8V core voltage aligns with system power rails and that I/O standards match the target interfaces.

Part Context

Part of the ispMACH 4000ZE CPLD family, offering enhanced features over the original 4000Z series including improved routing pools for better timing predictability and first-time-fit success rates. It serves as a bridge between simple PLDs and larger FPGAs.

Replacement Considerations

Direct pin-to-pin replacements within the same family include LC4032ZE variants with different speed grades or packages. Cross-family migration to ispMACH 4000Z requires verification of timing and I/O compatibility.
