Complex Programmable Logic Devices Procurement Notes

This specific part number is officially discontinued per Product Change Notification #09-10. Verification of current product status is required before procurement. Alternative orderable devices within the same family may be available; consult the manufacturer's discontinuation table for valid replacements.

Complex Programmable Logic Devices Selection Notes

Select this component only if legacy compatibility with the ispLSI 2032V pinout is mandatory. For new designs, the datasheet recommends using the ispLSI 2032VE-300 series due to superior speed performance. Ensure design tools support the specific speed grade of 225 MHz.

Complex Programmable Logic Devices Part Context

The ispLSI 2032VE-225LJ44 belongs to the SuperFAST™ PLD family. It is functionally and pinout compatible with the earlier ispLSI 2032V devices but utilizes advanced E²CMOS technology for lower voltage operation and higher speeds. The 'LJ44' suffix denotes the commercial grade temperature range and the 44-pin PLCC package type.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends the ispLSI 2032VE-300LT44 or ispLSI 2032VE-300LB49 for new designs. These parts offer improved timing specifications (3.0 ns) compared to the -225 variant.
