Programmable Logic Device Pld Procurement Notes

This part number has been officially discontinued per Product Change Notification (PCN) #13-10 issued by Lattice Semiconductor. Verification of availability requires checking authorized distributors or secondary market suppliers such as Rochester Electronics. No new production units are available directly from the manufacturer.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with specific PAL architectures (e.g., 20R8, 20L8) is required. Verify that the 25 ns speed grade meets system timing requirements. Ensure design tools support the GAL20V8 device type for proper OLMC configuration mapping.

Programmable Logic Device Pld Part Context

The GAL20V8B series belongs to the GAL family of Electrically Erasable PLDs. This specific variant represents the industrial temperature grade (-40°C to +85°C) with a 25 ns speed rating. It is packaged in a 28-pin Plastic Leadless Chip Carrier (PLCC) with lead-free solder composition indicated by the 'N' suffix.

Programmable Logic Device Pld Replacement Considerations

No direct functional replacements are listed in the provided documentation due to the discontinuation of the entire GAL20V8 product line. Legacy designs may require migration to modern CPLD families or verification of existing stock through third-party inventory channels.
