Complex Programmable Logic Devices Procurement Notes

Verify product status against Product Change Notification #09-10, which indicates discontinuation for select devices in the ispLSI 2032VE family. Confirm current availability directly with Lattice Semiconductor or authorized distributors before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 135 MHz performance in a 44-pin PLCC package. Ensure compatibility with 3.3V supply rails while maintaining interface capability with 5V TTL signals. Consider alternative speed grades or packages if higher frequencies or different form factors are required.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2032VE family of SuperFAST™ High Density PLDs. It is functionally and pinout compatible with the earlier ispLSI 2032V devices but operates on a 3.3V architecture. The -135LJ44 suffix denotes the 135 MHz speed grade and 44-pin PLCC package.

Complex Programmable Logic Devices Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Refer to Lattice Semiconductor for recommended upgrades or cross-references due to the discontinuation notice.
