Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'LJN' corresponds to the lead-free 44-pin PLCC package as defined in the datasheet. Confirm industrial temperature grade availability via the 'I' suffix. Check current product status as some variants may be discontinued per PCN #02-06.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 32 I/Os and non-volatile reconfigurability. Ensure the system operates at 5V for ISP functionality. Compare against the recommended ispLSI 2032E for new designs if higher performance or updated features are required.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which bridges the gap between PLDs and FPGAs. The 'A' variant is fully form and function compatible with the original ispLSI 2032 but utilizes an advanced 0.35 micron process for improved performance and density.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E is recommended by Lattice for new designs. Direct pin-compatible replacements include other members of the ispLSI 2032/A series with different speed grades or package types, such as the -110 or -135 variants.
