Complex Programmable Logic Devices Procurement Notes

Product Change Notification (PCN) #09-10 indicates that the ispLSI 2032VE series, including this part number, has been discontinued. Verification of current product status against the manufacturer's official discontinuation list is required before procurement planning.

Complex Programmable Logic Devices Selection Notes

This component provides 100% functional and pinout compatibility with the older ispLSI 2032V devices. For new designs requiring higher performance, the datasheet recommends using the ispLSI 2032VE-300 variant instead.

Complex Programmable Logic Devices Part Context

The 'LJ44' suffix identifies the specific package as a 44-pin Plastic Leaded Chip Carrier (PLCC). This packaging option is distinct from the TQFP, LT48, or caBGA variants available within the same electrical family.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032VE-300LJ44 is functionally compatible but offers higher speed (300 MHz fmax, 3.0 ns tpd). Other speed grades like -110LJ44 or -135LJ44 are also pin-compatible alternatives within the same package.
