Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence. Confirm that the specific ordering suffix matches required speed grades and environmental specifications before procurement.

Complex Programmable Logic Devices Selection Notes

Select the -5 speed grade for designs requiring a maximum propagation delay of 5 ns and operating frequencies up to 192.3 MHz. Ensure the design utilizes the 144-pin TQFP package constraints and accounts for the 96 available user I/O pins within the MAX 3000A architecture.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A series, which provides high-density PLDs ranging from 600 to 10,000 usable gates. The EPM3128A variant specifically offers 2,500 usable gates and 128 macrocells, bridging the gap between smaller EPM3064A and larger EPM3256A devices.

Complex Programmable Logic Devices Replacement Considerations

Compatible alternatives within the same family include EPM3128ATC144-10N and EPM3128ATC144-7N, which share identical pinouts and logic resources but differ in speed grades.
