Complex Programmable Logic Devices Procurement Notes

Verify current availability status directly with Lattice Semiconductor or authorized distributors. Although the datasheet lists this specific part number as Active/Orderable, confirm lead times and packaging options prior to ordering. Ensure design compatibility with the MACH 4 family specifications.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring 128 macrocells and 64 I/Os with a 7.5 ns speed grade. The 'N' suffix indicates specific internal routing or feature variations compared to standard M4-128/64 variants. Verify package requirements against Table 3 in the datasheet to ensure physical fitment.

Complex Programmable Logic Devices Part Context

This device belongs to the MACH 4 CPLD family, which offers densities from 32 to 256 macrocells. The M4-128N/64 variant provides a specific configuration within the 128-macrocell tier. Other devices in the family include M4-32/32, M4-64/32, and M4-256/128, with varying I/O counts and package options.

Complex Programmable Logic Devices Replacement Considerations

Lattice has issued Product Change Notifications (PCNs) converting many MACH 4 devices to the M4A5 family. However, the M4-128N/64 series is explicitly listed as Active/Orderable in the provided datasheet table, distinct from the converted M4-128/64 series. Consult PCN documentation for any future obsolescence notices.
