Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status as datasheets may indicate variations between compliant and non-compliant versions for this part number. Confirm the specific suffix 'N' denotes the correct environmental rating required for the target assembly process. Check for recent Product Change Notifications regarding label changes or manufacturing site updates before finalizing orders.

Complex Programmable Logic Devices Selection Notes

Select this model when 440 macrocells and 160 I/Os are sufficient for the design. Ensure the PCB layout accommodates the 256-FBGA footprint. Compare against EPM570GT variants if TQFP packaging is preferred over BGA. Verify that the 1.8V core voltage aligns with the system's power delivery network capabilities.

Complex Programmable Logic Devices Part Context

This component is part of Intel's (formerly Altera) MAX II family, designed for low-cost, low-power applications requiring non-volatile programmability. It serves as a drop-in replacement for many older discrete logic solutions. The GF suffix typically indicates a specific pinout or package variant within the broader EPM570 series.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other EPM570 variants with different packages such as EPM570GT256C3N (TQFP) or EPM570GF256I3N (Industrial temp). Cross-family upgrades like EPM1270GF256C3N offer higher density but require verification of pin compatibility and software tool support.
