Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'I5' confirms the industrial temperature grade (-40°C to 100°C) and 6.2ns speed grade. Confirm RoHS compliance status as historical data indicates some variants may not meet current standards. Ensure the 256-FBGA footprint matches the target PCB design constraints.

Complex Programmable Logic Devices Selection Notes

Select this model over commercial grades when operation in extreme temperatures is required. Verify that the 2.5V/3.3V dual voltage capability aligns with the system's power rails. Consider the 256-pin package size relative to available board space compared to smaller pin-count alternatives.

Complex Programmable Logic Devices Part Context

This component belongs to the Intel (formerly Altera) MAX II family, designed for low-cost, low-power CPLD applications. It serves as a successor to older GAL and PAL devices, offering reprogrammability and higher density than discrete logic solutions while maintaining simplicity.

Complex Programmable Logic Devices Replacement Considerations

Direct substitute: EPM1270F256I5. Note that the 'N' suffix typically denotes lead-free packaging; verify if the base part number without 'N' is functionally identical regarding electrical parameters.
