Part Context

This part belongs to the Lattice ispMACH 4000V series, designed for high-performance applications requiring low power consumption. The 'V' suffix indicates the specific variant within the family, while 'TN128' denotes the 128-pin Thin Quad Flat Package. It serves as a drop-in replacement for older GAL devices in many legacy designs.

Replacement Considerations

Direct pin-compatible alternatives within the same package include the LA4128V-75TN144E (144-pin) or LA4128ZC-75TN128E if voltage requirements differ. Verify logic density needs against the LA4256V series for higher capacity.
