Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix corresponds to the required temperature range and package variant. Ensure compliance with RoHS directives if lead-free packaging is mandated for the target assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model when design requirements exceed the capacity of lower-density PLDs but do not necessitate FPGA flexibility. The 128 macrocell count and 28 I/Os suit moderate complexity logic. Verify that the 3.3V core voltage aligns with the system power budget and that the TQFP-100 footprint fits the PCB constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2128VE family, representing an evolution of the popular ispLSI 2128 series. It maintains functional compatibility with the original 2128 while offering improved speed performance and enhanced in-system programming capabilities. The device bridges the gap between traditional PLDs and FPGAs in terms of density and ease of use.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128VE-135LTN100I is functionally and pin-compatible with the ispLSI 2128V-135LTN100I. Designers migrating from the V-series can utilize this VE-version as a drop-in replacement without schematic modifications.
