Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix for lead-free compliance, as the datasheet distinguishes between conventional and lead-free packages. Confirm current product status, as certain devices in this family have been discontinued per PCN #02-06. Ensure compatibility with existing 44-pin TQFP footprints during procurement planning.

Complex Programmable Logic Devices Selection Notes

Select the -80 speed grade for designs requiring an 84 MHz maximum operating frequency. Verify that the application requires a 5V core voltage, as the device is not compatible with lower voltage cores without specific variants. Consider the ispLSI 2032E series for new designs due to enhanced performance specifications.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which offers form and function compatibility with the original ispLSI 2032. It is built on an advanced 0.35 micron E2CMOS process. The device provides non-volatile storage for logic configurations, allowing for field reprogrammability without erasing the entire chip.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E series is recommended for new designs. For direct pin-compatible replacements within the same family, consider the ispLSI 2032A-80LJ44 (PLCC package) or ispLSI 2032A-80LTN48 (Lead-Free TQFP). Verify discontinuation status before substitution.
