LC4064ZE-4MN144C

Complex Programmable Logic Devices Overview

The LC4064ZE-4MN144C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000ZE family. It integrates 64 macrocells and features 128 I/Os within a 144-pin TQFP package. The device operates with a 1.8 V core voltage, achieving a maximum frequency of 333 MHz and a typical propagation delay of 2.7 ns. It supports LVCMOS 3.3, LVTTL, and PCI interfaces with 5 V tolerant I/Os. The component utilizes EECMOS non-volatile technology and includes JTAG in-system programmability for flexible configuration.

• Address decoding and bus arbitration in embedded computing architectures.
• State machine implementation for test and measurement instrumentation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '4MN144C' against official Lattice documentation to confirm pinout and electrical characteristics, as variations exist within the 4000ZE series. Confirm RoHS compliance status through current manufacturer declarations. Check for end-of-life or not-for-new-designation notices, as older CPLD families may have limited long-term availability. Ensure design tools support the specific device variant for accurate timing analysis.

Complex Programmable Logic Devices Selection Notes

Select this device when 64 macrocells are sufficient for the target logic density and 128 I/Os are required. The 1.8 V core voltage offers lower dynamic power compared to older 3.3 V CPLDs, while 5 V tolerant inputs simplify interfacing. The TQFP-144 package provides accessible pins for prototyping but requires consideration of thermal dissipation in dense PCB layouts. Compare against the LC4064ZE-4TCN100C if fewer I/Os are acceptable for a smaller footprint.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000ZE family, which blends ispLSI 2000 and ispMACH 4A architectures. The ZE series emphasizes low power consumption and SuperFAST performance. It serves as a successor to earlier generations, offering improved timing predictability and routing resources. The family is designed for applications requiring non-volatile logic with high reliability and ease of use.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, 144-pin TQFP package, and 1.8 V core voltage. Verify that any substitute maintains 5 V tolerant I/O capabilities and similar propagation delays. Cross-reference pinouts carefully, as package variations within the same logic density may differ. Consult Lattice's official migration guides for architectural compatibility.
