LC4032ZE-5MN64I

Overview

The LC4032ZE-5MN64I is a complex programmable logic device (CPLD) belonging to the ispMACH 4000EZ family, manufactured by Lattice Semiconductor Corporation. It features 32 macrocells and operates with a maximum frequency of 250 MHz and a propagation delay of 5 ns. The device supports 3.3V I/O levels and includes 28 user I/O pins within a 64-pin TQFP package. Key specifications include 16K bits of system memory and support for in-system programming via JTAG.

Feature Summary

• ispMACH 4000EZ architecture with 32 macrocells and 16K bits of embedded SRAM
• High performance: 250 MHz max frequency, 5 ns propagation delay
• Supports 3.3V I/O with flexible voltage translation capabilities
• In-system programmability via JTAG interface

Applications

• Interface bridging between different voltage domains
• Address decoding and glue logic in embedded systems
• State machine implementation for control applications
• Bus buffering and protocol conversion

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status. Confirm the '-E' variant meets extended temperature range requirements if operating in harsh environments. Ensure the MN64 package matches the PCB footprint design. Check for recent product change notices regarding marking or packaging updates from Lattice Semiconductor.

Selection Notes

Select this part when 32 macrocells are sufficient for the logic density required. The 5 ns speed grade is suitable for moderate-speed digital interfaces. Consider the 64-pin TQFP package for through-hole or surface-mount assembly depending on manufacturing capabilities. Verify power supply constraints align with the 3.3V operation mode.

Part Context

This component is part of the ispMACH 4000EZ family, designed for high-density, low-power CPLD applications. It succeeds earlier ispMACH 4000 variants with improved performance and lower power consumption. The EZ series integrates non-volatile configuration memory, allowing for instant-on functionality without external configuration devices.

Replacement Considerations

Direct pin-to-pin replacements may include other members of the ispMACH 4000EZ family with similar macrocell counts, such as the LC4032ZE-5TN100I for larger packages. Cross-family migration to MachXO2 or iCE40 FPGA families requires significant design re-verification due to architectural differences.
