Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '135' corresponds to the required 135 MHz performance specification. Confirm the 'LB100' suffix indicates the 100-lead Thin Quad Flat Package (TQFP) variant. Ensure design tools support the ispLSI 2128VE family for programming and configuration.

Complex Programmable Logic Devices Selection Notes

Select this component when high density and fast global interconnect are required for complex logic functions. The 135 speed grade suits applications needing up to 135 MHz operation. Consider the 128 I/O pin version if extensive external connectivity is necessary compared to the 64 I/O variant.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128VE series, which offers enhanced pin locking and flexible pin placement. It is functionally and pinout compatible with the earlier ispLSI 2128V devices, allowing for potential migration or replacement in existing designs utilizing the V series.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128VE is 100% functionally and pinout compatible with the ispLSI 2128V. Designers can substitute the VE series for the V series without hardware changes, provided the VE speed grades meet the timing requirements.
