Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the package matches the 176-pin TQFP specification. Check for moisture sensitivity indicators as the device requires proper handling. Ensure the ordering suffix corresponds to the industrial or commercial grade required for the specific application environment.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 100 MHz performance are sufficient for the design requirements. The -100 speed grade provides a 10 ns propagation delay. The LT176 suffix indicates the 176-pin TQFP package. Consider the ispLSI 2128E for new designs if higher density or updated features are needed, as the 2128A is functionally compatible with the original 2128.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2128/A family of high-density PLDs. It is fully form and function compatible with the ispLSI 2128, sharing identical timing specifications and packaging options. The device utilizes a Global Routing Pool (GRP) to provide complete interconnectivity between its 32 Generic Logic Blocks and I/O cells.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128A-100LT176 is functionally equivalent to the ispLSI 2128-100LT176. For new designs, Lattice recommends using the ispLSI 2128E series. Verify pinout compatibility before substituting with other CPLD families.
