Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '7' against official Lattice documentation to confirm the exact speed grade and temperature range, as datasheets may list generic family parameters. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement to ensure compatibility with assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this component when design requirements necessitate low power consumption combined with high-speed logic capabilities. The 1.8V core voltage makes it suitable for battery-powered applications. Ensure the 32 macrocell density meets logic resource needs without excessive overhead compared to larger devices like the LC4064ZE.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000ZE series, an evolution of the ispMACH 4000Z architecture. The ZE series introduces enhanced I/O features such as slew rate control, PCI compatibility, and hot socketing support, distinguishing it from earlier generations while maintaining pin-out retention for migration purposes.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include the LC4032V-7TN48C or other variants in the LC4032ZE series with compatible packages. Verify that any substitute maintains the required 1.8V ISP capability and I/O voltage levels.
