Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000A series, an evolution of the original MAX 7000 line. The 'AE' suffix denotes the 3.3V variant with enhanced performance characteristics compared to the standard 5V or lower-speed 3.3V versions. The FC256 suffix indicates the 256-pin FineLine BGA package. This specific model represents a high-density option within the 128-macrocell class, offering higher speed than the S-series counterparts while maintaining the same logical capacity.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the end-of-life status of the MAX 7000 family. Functional equivalents may require redesigning the PCB layout. Alternative CPLDs from current product lines, such as the MAX 10 or Agilex families, offer similar logic density but differ significantly in pinout, voltage requirements, and programming interfaces.
