LC4032ZC-5M56I

Overview

The LC4032ZC-5M56I is a complex programmable logic device (CPLD) belonging to the ispMACH 4000Z 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 utilizes a 56-pin TQFP package and supports in-system programming via JTAG. It is designed for high-density applications requiring low power consumption and flexible I/O configurations within a compact form factor.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells and up to 180 usable I/O pins
• High performance with fmax of 250 MHz and tpd of 5 ns
• Supports in-system programming and boundary scan testing via JTAG interface
• Low power consumption with advanced CMOS technology

Applications

• Interface bridging between different voltage domains
• Address decoding and control logic in embedded systems
• State machine implementation for industrial control
• Replacement for legacy GAL devices in existing designs

Procurement Notes

Verify the specific suffix 'ZC' indicates the commercial temperature range and lead-free status. Confirm the '5' speed grade matches the required timing constraints for the target design. Ensure the 'M56I' designation corresponds to the 56-pin TQFP package with industrial temperature rating if applicable, though standard Z series often implies commercial; cross-reference the full part number against the manufacturer's current datasheet to confirm exact electrical specifications and availability.

Selection Notes

Select this component when 32 macrocells are sufficient for the logic density requirements. The 5 ns delay meets most medium-speed digital logic needs. Consider the TQFP package for through-hole or standard surface mount assembly. Verify that the I/O voltage levels (3.3V, 2.5V, or 1.8V) align with the system interfaces. Compare against the LC4032V/B/C variants if higher speed or different packaging options are needed.

Part Context

This part is part of the ispMACH 4000Z family, which succeeded the earlier ispMACH 4000V/B/C series. It offers improved performance and lower power compared to previous generations while maintaining pin-to-pin compatibility with many legacy CPLDs. The Z series is optimized for cost-effective, high-volume applications requiring reliable programmable logic.

Replacement Considerations

Direct replacements include other parts from the ispMACH 4000Z family with equivalent or higher macrocell counts, such as the LC4032ZE-5T100I for larger packages. Legacy equivalents like the GAL16V8 or GAL22V10 may require logic restructuring. Check for pin-compatible upgrades from the LC4032V/B/C series if the original design used those variants.
