Product details

Sourcing a legacy PLD — lifecycle and availability

Lattice Semiconductor has marked the GAL22V10D-15QPN as Obsolete. Because the manufacturer no longer produces this exact order code, sourcing runs through independent distribution channels that hold new-old-stock or verified surplus inventory.

Parametric fit for existing designs

The GAL22V10D-15QPN is an electrically erasable PLD (EE PLD) in the GAL®22V10 series. It integrates 10 macrocells with a maximum propagation delay (tpd) of 15 ns — the combinatorial path from input to registered output settles within that window, which sets the upper bound on the clock frequency the device can support in a given logic path. Operating temperature is 0°C to 75°C, the commercial-grade band; this part was not specified for industrial or automotive ambient ranges. The 0.100" pitch and standard DIP footprint make it a drop-in replacement for existing socketed or wave-soldered GAL22V10 designs — no board layout change is needed to swap this specific order code.

Frequently asked questions

Where can I buy the GAL22V10D-15QPN and what is its availability?

The GAL22V10D-15QPN is obsolete from Lattice Semiconductor. No stock-holding or lead-time number is stated here.

What is the closest pin-compatible alternative to the GAL22V10D-15QPN?

The GAL22V10 architecture was replaced by the ispGAL22V10 (in-system programmable, same 24-pin DIP footprint) and later by the ispMACH 4000 family, but those devices use different programming protocols and toolchains — a board redesign is required. Within the same GAL22V10 family, other speed grades (e.g., -7, -10, -25) and temperature ranges exist in the same 24-DIP package, but none is a direct second-source for the -15QPN commercial-grade variant.

What compliance documentation does Lattice Semiconductor provide for the GAL22V10D-15QPN?

The GAL22V10 series predates widespread RoHS adoption — confirm the date code and compliance status with the supplier at quote time.
