Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'A5N' against official Intel/Altera documentation to confirm voltage and temperature ratings, as variations exist within the MAX II series. Confirm RoHS compliance status and lead-free pin availability. Check for obsolescence notices or product change notifications related to this specific part number before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select the EPM570T144A5N when designs require moderate logic density with high I/O count in a surface-mount package. Ensure the design fits within the 440 macrocell limit and utilizes the available 116 I/O pins. Verify that the 7.1 ns delay meets timing requirements for the target clock speeds up to 304 MHz. Consider the 2.5V/3.3V dual-voltage support for interface compatibility.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, which introduced on-chip flash technology to CPLDs, eliminating the need for external configuration devices. The MAX II series is designed for cost-sensitive applications requiring reprogrammability. The EPM570 variant offers a balance between logic capacity and pin count, serving as a drop-in replacement for older GALs or smaller CPLDs in legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other MAX II devices with similar macrocell counts, such as the EPM570T144C5N, though electrical parameters like delay times may vary. Always verify functional equivalence and timing constraints before substitution.
