Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor under Product Change Notification (PCN) #09-10. Verification of current availability requires checking authorized distributors or secondary market suppliers, as the manufacturer no longer produces this part number.

Programmable Logic Device Pld Selection Notes

Designers should evaluate the ispGAL22LV10 family or newer SPLD alternatives for new designs due to the discontinuation status. Ensure that the 1.8V core voltage requirement and 3.3V I/O interface compatibility match the target system specifications before considering legacy stock.

Programmable Logic Device Pld Part Context

The ispGAL22V10A series represents an evolution of the classic GAL22V10 architecture, offering reconfigurable logic with lower power consumption. The 'AC' suffix denotes the 1.8V core voltage variant, while '-5' indicates the 5.0ns speed grade, and 'I' specifies the Industrial temperature range.

Programmable Logic Device Pld Replacement Considerations

Lattice recommends evaluating the ispMACH 4000V series as a modern replacement for the mature ispGAL22V10 devices. Check specific PCNs for exact cross-referencing guidance.
