Programmable Logic Device Pld Procurement Notes

This component is officially discontinued by Lattice Semiconductor. Product Change Notifications (PCNs), specifically PCN#06-07 and PCN#13-10, confirm the end-of-life status for all devices in the GAL26CV12 datasheet. Verification of current availability requires checking secondary market distributors, as original manufacturer stock is no longer produced.

Programmable Logic Device Pld Selection Notes

Select this part for legacy designs requiring a 26-input, 12-output SPLD with registered outputs. The 20 ns speed grade suits applications with moderate timing requirements up to 50 MHz. Ensure compatibility with the 28-pin DIP footprint. For new designs, consider modern CPLD alternatives due to the discontinued status of this specific part number.

Programmable Logic Device Pld Part Context

The GAL26CV12 series belongs to Lattice's Generic Array Logic (GAL) family, designed to replace complex bipolar PALs with lower power CMOS equivalents. This specific model represents a high-density variant within the GAL line, offering 12 macrocells. The 'LJI' suffix indicates a specific industrial temperature range and lead-free compliant packaging option available at the time of production.

Programmable Logic Device Pld Replacement Considerations

As the GAL26CV12B-20LJI is discontinued, direct pin-to-pin replacements are not guaranteed. Review Lattice's product change notifications for any final recommended substitutes. Modern FPGA or CPLD families may require schematic modifications due to differences in logic architecture and I/O configurations.
