Programmable Logic Device Pld Procurement Notes

This part number is officially discontinued per Product Change Notification PCN#09-10 issued by Lattice Semiconductor. No new production units are available from the manufacturer. Verification of authenticity is critical when sourcing from secondary markets due to the age of the component and potential availability of obsolete stock.

Programmable Logic Device Pld Selection Notes

Select this component only for legacy designs requiring specific pinouts and timing characteristics of the GAL16V8D series. The -20 speed grade indicates a 20 ns maximum propagation delay. Designers must account for the end-of-life status and ensure that alternative SPLDs or CPLDs can meet the functional requirements if replacement becomes necessary.

Programmable Logic Device Pld Part Context

The GAL16V8D-20QPI belongs to the GAL16V8D product line, which represents the low-power variant of the Generic Array Logic family. The 'Q' suffix denotes Quarter Power consumption, and 'PI' indicates a Plastic PLCC package with Industrial temperature rating capabilities, although the datasheet primarily lists Commercial specifications for this specific ordering code context.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinuation status, designers should evaluate modern Lattice CPLDs or generic FPGA alternatives that offer pin-compatible footprints and similar logic density.
