Complex Programmable Logic Devices Procurement Notes

Verify component authenticity upon receipt as this part number is from a discontinued product line. Confirm that the specific ordering suffix matches the required speed grade (-7) and package type (PLCC-44). Ensure handling procedures account for moisture sensitivity classification prior to soldering.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. The -7 speed grade provides a 6 ns delay suitable for moderate-frequency applications. Note that MultiVolt I/O interface operation is not available in the 44-pin package configuration; verify voltage compatibility constraints before finalizing the selection.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 family, which utilizes second-generation MAX architecture. The family ranges from 600 to 5,000 usable gates. The EPM7064 variant specifically offers a balance of density and pin count within the 44-pin form factor, serving as a high-density solution for legacy system upgrades.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the same package include the EPM7064AE series (3.3-V operation) and EPM7064B series (2.5-V operation). Verify that the replacement device supports the required 5.0-V supply voltage if the original circuit design does not support multi-voltage I/O.
