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 -5 speed grade matches the required 5 ns propagation delay for the target design. Ensure the TQFP-144 package footprint aligns with the PCB layout specifications.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 96 user I/O pins are sufficient for the design complexity. The -5 speed grade provides a 5 ns delay, suitable for applications requiring up to 192.3 MHz counter frequencies. Consider the MultiVolt capability if interfacing with mixed-voltage peripherals.

Complex Programmable Logic Devices Part Context

This device is part of the MAX 3000A series, which offers high-density PLDs ranging from 600 to 10,000 usable gates. The EPM3128A variant specifically bridges lower-density options like the EPM3064A and higher-density models such as the EPM3256A, providing a balance of logic resources and pin count.

Complex Programmable Logic Devices Replacement Considerations

Compatible alternatives within the same family include EPM3128ATC144-10N and EPM3128ATC144-7N. These variants share identical pinouts and logical structures but differ in speed grades (-10 ns and -7.5 ns respectively). Verify timing requirements before substitution.
