Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'RR' against official Intel/Altera documentation to confirm it denotes a standard tape-and-reel packaging variant rather than a distinct electrical specification change. Ensure the ordering part number matches the exact package marking and moisture sensitivity level requirements for your assembly process. Cross-reference the datasheet revision history for any recent label or PCN updates that may affect physical dimensions or marking codes.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile CPLD solution is required to eliminate boot-up delays associated with volatile SRAM-based FPGAs. The MAX II family provides a cost-effective alternative for designs needing moderate logic density without the complexity of FPGA configuration controllers. Consider the 256-pin FBGA footprint for board space constraints and verify thermal dissipation capabilities within the 0°C to 85°C industrial temperature range.

Complex Programmable Logic Devices Part Context

This device is part of the Altera MAX II family, which targets low-power, high-density applications requiring instant-on functionality. The family is characterized by its use of non-volatile Flash technology, allowing for immediate operation upon power application. The EPM1270 variant represents a mid-range density option within this series, balancing logic capacity with pin count for versatile digital design implementations.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing programming tools such as Quartus software before considering alternative devices from the same manufacturer or competitor families.
