Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status as indicated on official datasheets. Check for End-of-Life (EOL) notices or Product Change Notifications (PCNs) from Altera/Intel prior to procurement decisions.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells and high-density I/O in a TQFP package. Ensure design timing constraints align with the -10 speed grade (5 ns tPD). Verify that the 3.3 V core voltage meets system power requirements and that ISP capabilities are utilized for manufacturing efficiency.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A family, which offers low-cost, high-performance CPLDs ranging from 600 to 10,000 usable gates. The EPM3128A variant specifically provides 2,500 usable gates and supports industrial temperature ranges. It is designed to replace legacy PALs, GALs, and pLSI devices with modern reprogrammable logic.

Complex Programmable Logic Devices Replacement Considerations

Compatible speed grades within the MAX 3000A family include -4, -5, -6, and -7 variants of the EPM3128A. These share identical pinouts and functionality but offer different propagation delays. No direct cross-manufacturer substitutes are documented in the provided source material.
