Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I5' against official datasheets to confirm industrial temperature range (-40°C to +85°C) and voltage specifications. Ensure compatibility with Quartus II software versions supporting the MAX II family. Check for RoHS compliance documentation and moisture sensitivity levels prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 440 macrocells and 160 I/Os are required in a 256-pin BGA footprint. Compare against EPM570F256C5N for commercial temperature variants or EPM570GF256I5N for Green/lead-free options. Confirm that the 5.4 ns speed grade meets the target clock frequency requirements of the design.

Complex Programmable Logic Devices Part Context

This part is a member of the Altera MAX II family, designed as a low-cost, high-density CPLD solution. It serves as a successor to older MAX 7000 series devices, offering improved power efficiency and modern programming capabilities while maintaining pin-compatible options for legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include EPM570F256C5N (commercial temp) and EPM570GF256I5N (Green variant). For higher density needs, consider the EPM570T series, though pin counts may differ.
