Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet have been officially discontinued via Product Change Notifications (PCNs). The GAL16V8D-10QJ is no longer manufactured or distributed as a new product. Verification of availability requires checking secondary market sources or contacting authorized distributors for obsolete inventory status.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with specific PAL fuse maps or parametric characteristics is required. The 'Q' suffix indicates a Quarter Power variant with reduced typical supply current (45 mA) compared to Low Power versions. Ensure design tools support the GAL16V8 device type for proper OLMC configuration synthesis.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's high-speed PLD line based on E2CMOS technology. The 'D' suffix denotes the specific device family iteration, while 'QJ' identifies the Quarter Power speed grade packaged in a 20-pin Plastic Leadless Chip Carrier (PLCC). This part belongs to the broader GAL16V8 product line which includes DIP, SOIC, and PLCC package options.

Programmable Logic Device Pld Replacement Considerations

As the device is discontinued, direct replacements are not provided by Lattice. Designers should evaluate modern FPGA alternatives such as the iCE40 or MachXO series for new designs requiring similar logic density and low-power characteristics.
