Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'G' against the manufacturer's current Max II Device Order Guide, as packaging or label changes may affect part identification. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Check for any Product Change Notices regarding lead-free soldering profiles or labeling updates before finalizing procurement orders.

Complex Programmable Logic Devices Selection Notes

Select this component when 570 logic elements are required in a high-pin-count BGA footprint. Ensure the design utilizes the 1.8V core voltage domain compatible with the specified 1.71V–1.89V range. Verify that the target application requires ISP capabilities rather than external configuration devices. Compare pin counts and I/O flexibility against smaller variants like the EPM570T256 if space constraints allow.

Complex Programmable Logic Devices Part Context

This part belongs to the Intel (formerly Altera) MAX II family of non-volatile CPLDs. It utilizes Flash technology to retain configuration without external memory, simplifying board design compared to SRAM-based FPGAs. The MAX II series is positioned for low-power, cost-sensitive applications requiring moderate logic density and robust industrial reliability.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents within the same MAX II family include the EPM570M256I5N and EPM570T256I5N. These parts share identical logic resources and pinouts but differ in package type (MBGA vs. FBGA). Verify mechanical compatibility and thermal characteristics when substituting between package styles.
