Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by the manufacturer per Product Change Notification PCN#13-10. Verification of availability requires checking secondary market distributors or authorized liquidation partners. Designers should confirm that legacy inventory meets current functional specifications before integration into new systems.

Programmable Logic Device Pld Selection Notes

Select this part only if specific legacy compatibility with 20-pin PAL devices is required. The GAL16V8D-10LPI emulates various PAL architectures including 16R8, 16L8, and 10L8. Ensure the design tool supports the GAL16V8 device type for proper compiler configuration of the macrocell modes.

Programmable Logic Device Pld Part Context

The GAL16V8D series represents a line of Generic Array Logic devices designed to replace standard bipolar PALs with lower power CMOS alternatives. The 'D' suffix indicates the use of Electrically Erasable technology, allowing for reprogramming without UV exposure. This specific variant offers a balance between speed and power consumption compared to faster or lower-power siblings in the family.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available as the entire GAL16V8 device family has been discontinued. Replacement strategies typically involve migrating to modern FPGA families such as the MachXO or iCE40 series, which require architectural redesign rather than pin-for-pin substitution.
