Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'N' against official Lattice documentation to confirm package type and lead-free status. Ensure design compatibility with the recommended ispLSI 1048EA variant for new projects. Confirm voltage requirements match the 5V ISP specification.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 100 MHz performance with 10 ns propagation delay. Consider the -70 grade if lower speed is acceptable. Verify pin-out compatibility with existing ispLSI 1048C designs if migrating legacy systems.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 1048E family, which is a functional superset of the ispLSI 1048 architecture. It adds two global output enable pins and two dedicated inputs compared to previous versions. The device is designed as a drop-in replacement for ispLSI 1048C in terms of functionality and pin-out.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 1048EA for new designs. For existing designs, the ispLSI 1048E-70 is suggested as an alternative to the -50 grade.
