Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'LB272' corresponds to the 272-pin Ball Grid Array package option as defined in the official Lattice Semiconductor datasheet. Ensure design compatibility with the 3.3V VCC supply and optional 2.5V or 3.3V VCCIO requirements. Confirm that the -70 speed grade meets the timing constraints for the target application frequency.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require high density (512 macrocells) with flexible I/O voltage options. The SuperWIDE architecture with 68 inputs per GLB is optimal for large combinational functions. Consider the -70 speed grade for applications needing up to 110 MHz performance. Ensure the PCB layout supports the 272-pin BGA footprint and thermal requirements for the E2CMOS technology.

Complex Programmable Logic Devices Part Context

The ispLSI 5512VA belongs to the Lattice ispLSI 5000V family of high-density PLDs. It shares architectural similarities with the ispLSI 5000 series but offers enhanced pin-locking capabilities and SuperWIDE GLBs. This family is designed for applications transitioning from standard PLDs to higher complexity logic while maintaining in-system programmability benefits.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 5512VA is functionally compatible with previous generation ispLSI 5000 devices regarding logic density but differs in architecture. Direct pin-for-pin replacements may not exist for all packages; verify pinout compatibility if substituting into existing designs. Check for equivalent gate counts and I/O availability in other Lattice families like ispMACH 4000 if newer technologies are preferred.
