Complex Programmable Logic Devices Procurement Notes

Verify the specific package type for the QU suffix against official documentation, as datasheet diagrams show TQFP and PQFP options for 100-pin variants. Confirm temperature range requirements, as commercial and industrial grades are available within this family. Ensure design files account for the specific VCCINT and VCCIO power connections required for mixed-voltage operation.

Complex Programmable Logic Devices Selection Notes

Select this component when high-density logic with fast propagation delays is required. The 10 ns speed grade provides 7.5 ns max delay. Consider the 3.3V/5.0V dual-supply capability if interfacing with mixed-voltage systems. Verify that the 100-pin package fits the board layout constraints compared to 84 or 160-pin alternatives.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1508AS series of EEPLDs. It shares architectural features like enhanced routing resources and security fuses with other members of the family. The 'AS' designation indicates standard performance characteristics, while the '10' denotes the 7.5 ns speed grade. It is designed for applications requiring reprogrammability and robust I/O drive capabilities.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other ATF1508AS variants with different pin counts or speeds, such as ATF1508AS-10AU100 (TQFP) or ATF1508AS-10PU100 (PQFP), provided the package footprint matches. Verify voltage compatibility and pin assignments before substitution.
