Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Check for moisture sensitivity level (MSL) handling requirements if the lead-free PLCC variant is selected. Confirm that the specific speed grade matches design timing constraints before procurement.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring moderate logic density with 5V I/O compatibility. Ensure the 81 MHz operating speed meets system timing requirements. Consider the 84-pin PLCC package dimensions for PCB layout. Verify that the 4 mA source and 8 mA sink output drive capabilities are sufficient for the connected loads.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispLSI 2000A family of complex programmable logic devices. It is functionally compatible with the earlier ispLSI 2064 model but utilizes an advanced 0.35 micron process node. The device represents a transition point in Lattice's PLD portfolio, offering enhanced performance over previous generations while maintaining pin-to-pin compatibility.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI2064E is recommended by Lattice for new designs as a successor to the 2064/2064A series. Direct pin-compatible replacements may be available from third-party foundries like Rochester Electronics for discontinued standard packages, but verify electrical specifications carefully.
