Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000C series, designed as a drop-in replacement for older GALs and PALs while offering significantly higher density. The 'C' suffix denotes the specific generation within the 4000 family, characterized by its SuperFAST technology which balances speed and power consumption for general-purpose digital logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible substitutes within the same package may include other variants from the LC4128 family with different speed grades (e.g., LC4128C-75TN100I). Designers should verify voltage compatibility and timing requirements when selecting alternative speed grades.
