Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific ordering suffixes match required package variants and temperature grades. Ensure compliance with relevant export control classifications (ECCN 3A991) prior to acquisition.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for the target logic design. Verify that the 3.3V I/O levels align with connected system voltages. Consider the 256-pin FBGA footprint for PCB layout requirements. Compare against MAX 7000S series if 5.0V compatibility is necessary.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000AE family, representing an enhanced version of the original MAX 7000 series. It maintains pin compatibility with older 5.0V devices while offering improved performance and lower power consumption through 3.3V operation. The family is characterized by its robust ISP capabilities and widespread adoption in industrial applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other variants within the MAX 7000AE family such as EPM7128AETC100-6. For functional equivalents with different packages, consult Altera's cross-reference documentation for gate-count matching.
