Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet have been officially discontinued via Product Change Notifications (PCNs). The GAL16V8Z-15QJ is no longer manufactured by Lattice Semiconductor. Verification of availability requires contacting authorized distributors such as Rochester Electronics or Arrow Electronics for existing inventory or obsolescence management services.

Programmable Logic Device Pld Selection Notes

Select this component only for legacy system maintenance where pin-compatible replacement is critical. The 'Z' suffix indicates lead-free packaging, while '15' denotes a 15 ns speed grade and 'QJ' specifies Quarter Power consumption in a PLCC package. Ensure design tools support the GAL16V8 architecture for registered, complex, or simple macrocell configurations.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's entry into electrically erasable programmable logic devices, bridging the gap between one-time programmable PALs and flash-based FPGAs. It emulates various 20-pin PAL architectures with full function and parametric compatibility. The device was widely used before the dominance of modern low-power FPGAs like the iCE40 and MachXO series.

Programmable Logic Device Pld Replacement Considerations

Lattice recommends evaluating newer product families for new designs. Potential replacements include the Lattice MACH XO series or iCE40 ultra-low power FPGAs, which offer higher density and lower power consumption. Contact Lattice Semiconductor or authorized partners for specific cross-reference recommendations.
