Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to End-of-Life status. Check for moisture sensitivity packaging requirements before reflow soldering. Confirm RoHS compliance markings as original specifications may vary by production batch.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring high pin counts (100 I/O) in a compact FBGA footprint. Ensure voltage levels match the 3.3 V operating range. Consider thermal dissipation capabilities within the 256-ball grid array package for dense PCB layouts.

Complex Programmable Logic Devices Part Context

Part of the Altera MAX 7000B series, designed for high-density applications. It serves as a successor to the 5V MAX 7000S family while maintaining pin compatibility where applicable. The B suffix indicates specific speed grade and package variations within the EPM7128B line.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other EPM7128B variants with different speed grades or packages. Cross-family migration to MAX II or MAX V requires schematic redesign due to architectural differences.
