Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-100) against design timing requirements, as the datasheet specifies performance metrics for -100, -135, and -180 variants. Confirm package integrity for the 160-pin LQFP form factor. Ensure programming tools support the ISP TAP interface for in-system configuration.

Complex Programmable Logic Devices Selection Notes

Select this component when 6000 gate density and 100 I/Os are required within a 160-pin footprint. The -100 speed grade offers a balance between performance and power consumption compared to faster variants. Consider the -250 variant if higher switching speeds up to 250 MHz are necessary for new designs.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128VE family, which provides enhanced pin locking and flexible pin placement compared to previous generations. It is functionally and pinout compatible with the older ispLSI 2128V series, allowing for direct upgrades in existing designs while benefiting from improved 3.3V operation and lower power consumption.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128VE-100LQ160 is functionally equivalent to the ispLSI 2128V-100LQ160. Designers upgrading from the V series can utilize this VE version without schematic changes due to pinout compatibility.
