Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-70) against design timing requirements. Confirm package type (LQ indicates 128-pin PQFP). Check RoHS compliance status as older manufacturing runs may vary. Ensure programming tools support the ispLSI family architecture.

Complex Programmable Logic Devices Selection Notes

Select this component when 8,000 PLD gates and 96 I/Os are required. The -70 speed grade provides a 70 MHz maximum frequency. Compare against the functional superset ispLSI 1048EA for new designs. Consider thermal management if operating at high frequencies or temperatures.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 1048E series, which is an enhanced version of the ispLSI 1048 architecture. It adds two global output enable pins and two dedicated inputs compared to the base model. The datasheet recommends using the ispLSI 1048EA for new designs.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 1048C-70LQ is functionally compatible but lacks the enhanced features of the E variant. The ispLSI 1048EA series is the recommended successor for new designs, offering improved performance and features while maintaining pin compatibility.
