Lattice Semiconductor has marked the GAL22V10D-20LJNI as Obsolete. This means the manufacturer has ended production and there is no official last-time-buy window remaining. For a BOM line that still needs this exact order code, supply is limited to existing inventory held by independent distributors. No official successor or pin-compatible replacement is recorded from Lattice for this part.
The GAL22V10D-20LJNI is a member of Lattice's GAL®22V10 series of electrically erasable PLDs (EE PLD). It integrates 10 macrocells with a maximum propagation delay (tpd) of 20 ns. This speed grade determines the maximum system clock frequency the device can support — at 20 ns, the internal logic paths must settle within that window before the next clock edge. These conditions fit typical factory-floor or outdoor telecom enclosures where the ambient temperature stays within this band.
Housed in a 28-lead PLCC (J-Lead) package, the GAL22V10D-20LJNI is a surface-mount device. The PLCC footprint is 11.51 mm x 11.51 mm and uses J-bend leads that sit under the body, saving board area compared to a DIP but requiring a socket or reflow process. The J-lead form factor also provides some compliance for thermal cycling. The device ships in Tube packaging, which is typical for PLCC parts in low-to-medium volume. For pick-and-place assembly, the tube can be loaded into a tube feeder or the parts transferred to tape-and-reel by the distributor.
