Programmable Logic Device Pld Procurement Notes

This specific part number is officially discontinued. Product Change Notifications (PCNs) confirm that all devices in the GAL20V8 datasheet are no longer in production. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory, as direct manufacturing supply has ceased.

Programmable Logic Device Pld Selection Notes

Designers requiring new production should select modern equivalents from Lattice's CrossLink-NX or iCE40 families, or consider alternative SPLDs from manufacturers such as Microchip Technology. The GAL20V8Z-15QP is functionally compatible with other GAL20V8 variants regarding pinout and logic structure, though electrical parameters like speed grade may vary.

Programmable Logic Device Pld Part Context

The GAL20V8 series represents a generation of Electrically Erasable Programmable Logic Devices (EPLDs) designed to replace hardwired logic gates. The 'Z' suffix typically denotes a specific speed grade or package variant within the broader GAL20V8 product line, while 'QP' indicates the plastic quad flat pack package type.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements are limited due to discontinuation. Functional substitutes include the GAL20V8B-15QP or GAL20V8C-15QP from Lattice if obsolete stock exists. For new designs, Lattice recommends migrating to the CrossLink-NX series for comparable logic density with enhanced features.
