Programmable Logic Device Pld Procurement Notes

This component is officially discontinued by Lattice Semiconductor under Product Change Notification #09-10. No new production units are available from the manufacturer. Verification of authenticity is critical when sourcing from third-party distributors, as availability is limited to existing stock or surplus inventory.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with GAL22V10 or ispGAL22LV10 architectures is required. Ensure the design accommodates the 3.3V core voltage and 5V tolerant I/O levels. For new designs, consider modern SPLD replacements as this device is no longer in production.

Programmable Logic Device Pld Part Context

The ispGAL22V10A family represents Lattice's low-voltage E2CMOS SPLD line, functionally compatible with older GAL22V10 devices. The 'AV' suffix denotes the 3.3V supply variant, while '5' indicates the 5.0 ns speed grade. The 'LJ' suffix identifies the 28-pin PLCC package. This series was succeeded by newer technologies but remains relevant for maintaining existing industrial systems.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed direct substitutes are not listed in the provided datasheet due to the discontinuation status. Designers should consult Lattice's current SPLD portfolio for functional equivalents that support modern packaging and programming interfaces.
