LC4032ZE-5MN64C

Overview

The LC4032ZE-5MN64C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH® 4000ZE family manufactured by Lattice Semiconductor Corporation. This component features 32 macrocells and supports up to 48 I/O pins within a 64-pin TQFP package. It operates with a 1.8V core voltage and supports interface voltages of 3.3V, 2.5V, 1.8V, or 1.5V. The device offers a maximum operating frequency of 260 MHz and a typical propagation delay of 4.7 ns. Designed for low-power applications, it includes in-system programmability via IEEE Standard 1532.

Feature Summary

• ispMACH® 4000ZE architecture with 32 macrocells and 48 I/Os
• Maximum operating frequency of 260 MHz and 4.7 ns propagation delay
• 1.8V core supply with support for 3.3V/2.5V/1.8V/1.5V I/O levels
• In-system programmability using IEEE Standard 1532

Applications

• Low-power consumer electronics requiring flexible logic control
• Interface bridging between different voltage domains
• Address decoding and state machine implementation
• General-purpose digital logic replacement

Procurement Notes

Verify the specific suffix MN64C corresponds to the 64-pin TQFP package and commercial temperature range during sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure compatibility with the required programming hardware for IEEE 1532 in-system programming.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic density. The 48 I/O count suits moderate pin-count requirements. Choose this part over standard 4000Z variants if IEEE 1532 in-system programming capability is required. Verify that the 1.8V core voltage aligns with the system power budget.

Part Context

This CPLD is part of the ispMACH® 4000ZE family, which enhances the original ispMACH 4000Z architecture. The family provides improved timing predictability and routing through a robust Global Routing Pool. It serves as a drop-in upgrade for legacy designs needing lower power consumption and modern programming interfaces.

Replacement Considerations

Direct replacements include other devices from the ispMACH® 4000ZE family with equivalent or higher macrocell counts, such as the LC4064ZE series, provided pin-out retention or re-routing is acceptable. Cross-family migration to newer Lattice CPLDs may require schematic changes.
