Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm the lead-free TQFP-176 package matches design requirements. Check for moisture sensitivity indicators as the device is humidity sensitive. Ensure programming equipment supports the specific ISP interface protocols defined in the datasheet.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 I/Os and high-speed logic processing up to 81 MHz. The -80 speed grade offers a 10 ns delay suitable for moderate timing constraints. The LT suffix indicates a lead-free TQFP package; verify pinout compatibility if replacing older PQFP versions.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128/A family, which is fully form and function compatible with the original ispLSI 2128. The 'A' variant utilizes advanced 0.35 micron technology while maintaining identical specifications. It serves as a bridge between standard PLDs and FPGAs, offering field programmability.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes include the ispLSI 2128-80LTN176I. For new designs, Lattice recommends using the ispLSI 2128E series instead.
