Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I5N' against official manufacturer documentation to confirm the industrial temperature grade and speed variant. Confirm current production status and lifecycle stage, as availability may vary by region. Ensure compliance with RoHS directives and check Moisture Sensitivity Level (MSL 3) requirements for surface-mount assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this model when a 1.8V core voltage CPLD is required for high-density logic replacement. Compare pin counts and I/O capabilities against alternatives like the EPM570T series if different packaging is needed. Verify that the 116 available I/O pins meet the design's connectivity requirements and that the 440 macrocell count is sufficient for the target logic complexity.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, designed to replace complex discrete logic gates. The 'G' suffix typically denotes the specific generation or feature set within the EPM570 line, while 'I' indicates the industrial temperature range. It serves as a drop-in replacement for many older programmable logic devices in communication and industrial control equipment.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include EPM570GT144C3N and EPM570GT144C5N, though these differ in temperature ratings or speed grades. Cross-family migration to newer Intel FPGA families requires retiming and resource verification.
