Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C3N' against official manufacturer documentation to confirm the commercial temperature grade and package variant. Ensure compatibility with the Quartus software environment for programming. Check RoHS compliance status as indicated in current datasheets.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with Flash retention is required. Compare the 1270 logic element count against design requirements. Verify that the 144-LQFP footprint fits the PCB layout constraints. Confirm that the 6.2 ns delay meets timing specifications for the target application frequency.

Complex Programmable Logic Devices Part Context

This part is part of the Altera MAX II series, designed for low-power, cost-sensitive applications requiring reprogrammability. It serves as a successor to older EPROM-based CPLDs, offering easier integration through ISP capabilities.

Complex Programmable Logic Devices Replacement Considerations

Compatible variants within the same package include EPM1270T144I5N, which differs in temperature rating and speed grade. Verify pinout compatibility before substitution.
