Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) against design timing requirements, as this indicates the maximum propagation delay specification. Confirm that the 48-pin TQFP package dimensions match the target PCB footprint. Ensure the supply voltage regulator supports the specified 2.375 V to 2.625 V range, as the MAX 7000 family typically requires precise voltage levels for reliable operation. Check for moisture sensitivity labeling if the component has been stored for extended periods.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density of logic resources is required with non-volatile configuration capabilities. The MAX 7000 family is suitable for applications where power consumption must be minimized while maintaining deterministic timing characteristics. Consider the 40 I/O count and 64 macrocell capacity to ensure sufficient resource headroom for the intended logic functions. The TQFP package offers a surface-mount solution suitable for compact board designs.

Complex Programmable Logic Devices Part Context

The EPM7064BTC48-7 is part of the broader MAX 7000S series, which represents Altera's second-generation CPLD technology. This family bridges the gap between simple PLDs and more complex FPGAs, providing a cost-effective solution for medium-complexity logic designs. The 'B' in the part number typically denotes a specific speed grade or variant within the EPM7064 line, while 'TQFP-48' specifies the physical package type.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other speed grades within the same package, such as the EPM7064BTC48-3, though timing parameters will differ. Cross-family migration to newer Intel/Altera CPLD families requires schematic and code adaptation due to architectural differences.
