Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#09-10. Verification of availability requires checking secondary market sources or authorized distributors for remaining inventory. Ensure compatibility with existing designs as the device is no longer in active production by Lattice Semiconductor.

Programmable Logic Device Pld Selection Notes

Select this part for legacy 22V10-compatible designs requiring E2CMOS reprogrammability. Verify that the 15 ns speed grade meets timing requirements, as faster variants like the -7LP exist. Confirm package compatibility with the 28-pin PLCC footprint and ensure the commercial temperature range suits the application environment.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents Lattice's high-performance Generic Array Logic devices. The 'D' suffix indicates the DIP/PLCC/SOIC package family, while 'Q' denotes Quarter Power consumption. This specific model is part of the broader GAL22V10 family, which is fully function and fuse-map compatible with standard bipolar and UVCMOS 22V10 devices.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the discontinuation status. Designers should consult Lattice Semiconductor or authorized distributors for potential obsolescence management strategies or equivalent modern FPGA/CPLD alternatives.
