Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'F' against official manufacturer documentation, as standard MAX II part numbers typically utilize suffixes such as 'G', 'T', or 'Z'. Confirm RoHS compliance status, as some variants in this series are noted as non-compliant in public records. Check for active production status or Obsolete notices via official PCNs before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density of 440 macrocells is required with a 256-ball BGA footprint. Ensure the design accommodates the 1.8V core voltage requirements. Verify that the 160 I/O count meets interface needs, noting that not all pins may be available for general use depending on the specific pinout assignment.

Complex Programmable Logic Devices Part Context

This part belongs to the Intel (Altera) MAX II family, designed for low-power, cost-sensitive applications requiring non-volatile programmability. It serves as a successor to older GAL technologies, offering higher density and JTAG-based programming capabilities while maintaining compatibility with standard CPLD design flows.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other MAX II variants with similar macrocell counts, such as the EPM570GF256C3N or EPM570ZM256C6N. Pin-to-pin replacements require verifying the package dimensions and electrical characteristics match the original design constraints.
