• Address decoding circuits
• Simple state machine implementation

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix designation to confirm the exact speed grade and package variant. Ensure compatibility with 5V logic levels and check for any obsolescence notices from Intel/Altera before finalizing component selection for new designs.

Programmable Logic Device Pld Selection Notes

Select this component when low gate count and non-volatile storage are required without external configuration memory. Consider the 7.5 ns speed limit for timing constraints. Evaluate if modern FPGA alternatives better suit complex logic requirements or higher density needs.

Programmable Logic Device Pld Part Context

This part belongs to the EP220/EP224 series of EPROM-based PLDs. These devices were designed to replace fixed-logic gate arrays and offer reprogrammability. The family includes variants like EP220 and EP224 with differing pin counts and gate capacities.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other EP224 variants such as EP224LC-10 or EP224LC-12, which share the same package but differ in speed grades. Modern equivalents may require architectural migration due to the shift from EPROM to Flash or SRAM-based FPGAs.
