LC4032ZC-75MN56C

Overview

The LC4032ZC-75MN56C is a complex programmable logic device (CPLD) from the Lattice ispMACH 4000Z family. It features 32 macrocells and 36 logic blocks, housed in a 56-pin MN56 package. The component supports In-System Programmability (ISP) via EEPROM technology, allowing for non-volatile configuration without removal from the circuit board. Key electrical specifications include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 400 MHz. It operates within a supply voltage range of 1.8 V to 3.6 V and supports industrial temperature ranges.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells and 36 logic blocks
• In-System Programmability (ISP) using embedded EEPROM technology
• High performance with 7.5 ns max propagation delay and 400 MHz max frequency
• Flexible I/O support with independent output enable controls

Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for control logic
• Interface translation between different voltage domains
• General-purpose digital logic replacement

Procurement Notes

Verify the specific suffix 'MN56' corresponds to the required 56-pin package type during sourcing. Confirm that the design toolchain supports the ispMACH 4000Z family for programming. Ensure the selected supplier provides genuine components with traceable origins to avoid counterfeit risks associated with legacy CPLDs.

Selection Notes

Select this model when a low pin count solution with ISP capability is required. The 32 macrocell density is suitable for simple logic functions. Compare against the LC4032V series if lower cost is prioritized over the enhanced features of the Z family. Verify power supply requirements match the 1.8V to 3.6V operational range.

Part Context

This part belongs to the Lattice ispMACH 4000Z family, which offers high-density logic in small packages. The 'Z' designation typically indicates enhanced features or specific process improvements over the standard 'V' or 'B' variants. It serves as a drop-in replacement for older GALs and PALs in modern designs requiring reprogrammability.

Replacement Considerations

Direct substitutes include other parts from the LC4032 family such as LC4032V-75MN56C, provided pin compatibility and feature sets are verified. Cross-family replacements may require schematic changes due to differences in macrocell architecture and I/O capabilities.
