Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued per Product Change Notification (PCN) #06-07. No new units are manufactured by Lattice Semiconductor. Verification of availability requires checking secondary market distributors for existing inventory. Replacement components must be sourced as direct functional equivalents due to the end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with the 22V10 macrocell architecture is required. The -15 suffix indicates a 15 ns speed grade, which is slower than the -7 or -10 variants but offers lower power consumption. Ensure the design accommodates the 5V operating voltage and 75 mA typical supply current. Verify that the 20-pin DIP package fits the target PCB footprint.

Programmable Logic Device Pld Part Context

The GAL18V10 series belongs to Lattice's Generic Array Logic (GAL) family, bridging the gap between simple PALs and complex CPLDs. The 'B' denotes the specific device variant within the GAL18V10 line, while 'L' signifies low power consumption and 'P' indicates the Plastic DIP package. This series was designed to replace bipolar PALs with lower power CMOS alternatives while maintaining pin-to-pin compatibility.

Programmable Logic Device Pld Replacement Considerations

As the device is discontinued, verify cross-compatibility with other GAL18V10 variants (e.g., GAL18V10B-7LP) if speed requirements allow. For modern replacements, consider Lattice's MachXO or iCE40 families, though pinouts and architectures differ significantly. Check PCN #06-07 for official discontinuation details and potential stock from Rochester Electronics.
