Complex Programmable Logic Devices Procurement Notes

Verify the component status as some devices in this family may be discontinued per PCN #02-06. Confirm that the 'LJN' suffix denotes a lead-free 44-pin PLCC package. Ensure design tools support the specific timing constraints for the -110 speed grade. Check for availability through authorized distributors or secondary market suppliers like Rochester Electronics if standard channels are depleted.

Complex Programmable Logic Devices Selection Notes

Select the ISPLSI2032A-110LJN44 when a non-volatile PLD with 32 I/Os and 1000 gates is required. The -110 speed grade provides an fmax of 111 MHz, suitable for moderate-speed applications. Choose the LJN package for lead-free compliance in a 44-pin PLCC form factor. Consider the ispLSI2032E series for new designs if higher performance or updated features are needed.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2032/A family, which is fully form and function compatible with the original ispLSI 2032. The 'A' variant is built on an advanced 0.35 micron process. The 'LJN' suffix indicates a Lead-Free PLCC package. The '-110' suffix specifies the 111 MHz maximum frequency speed grade.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI2032A-110LJN44 is functionally equivalent to the ispLSI2032-110LJN44. For new designs, Lattice recommends using the ispLSI2032E series. Verify pinout compatibility if substituting with other packages like TQFP (LT44).
