Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels. Confirm package integrity for the 176-pin TQFP variant. Check for lead-free compliance if required by environmental standards. Ensure programming tools support the specific E2CMOS architecture. Review datasheet for absolute maximum ratings to prevent damage during handling.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring high pin count and moderate speed. The -80 speed grade provides 81 MHz performance. Choose the LT package for surface mount applications needing 176 pins. Consider the ispLSI 2128E for new designs as recommended by the manufacturer. Verify voltage compatibility with 5V TTL logic levels.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2000AE family of PLDs. It serves as an upgrade to the original ispLSI 2128 with identical functionality but improved manufacturing processes. It bridges the gap between standard PLDs and FPGAs in terms of density and flexibility.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128 is functionally compatible. For new designs, Lattice recommends the ispLSI 2128E. Verify pinout compatibility when substituting with other high-density PLDs from different manufacturers.
