Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific speed grade (-150) and package type (LJ44) match design requirements. Check current product status as some devices in this family may be discontinued; consult official Product Change Notifications for availability details.

Complex Programmable Logic Devices Selection Notes

Select the -150 speed grade for designs requiring up to 154 MHz performance. Ensure the 44-pin PLCC package fits the PCB layout constraints. Verify that the 5V supply voltage and TTL-compatible I/O levels align with the system interface requirements. Consider the -180 grade if higher speed is needed, or the -135/-110 grades for lower power consumption.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2032/A family of high-density CPLDs. The 'A' suffix denotes an enhancement built on 0.35-micron technology while maintaining form and function compatibility with the original ispLSI 2032. The '150' indicates the 154 MHz speed bin, and 'LJ44' specifies the leaded 44-pin PLCC package.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032A is fully form and function compatible with the ispLSI 2032. For new designs, Lattice recommends using the ispLSI 2032E series instead.
