Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Ensure compatibility with existing PCB footprints for the 256-LBGA package before procurement. Check for available EDA/CAD models for design integration.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macrocells are sufficient for the target logic density. The 7.5 ns speed grade is suitable for moderate-frequency applications. Consider the FT256 package only if the system requires 192 accessible I/O pins. Verify that the 3V-3.6V internal supply range aligns with the system's power budget and I/O voltage requirements.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000V series, which integrates features from the ispLSI 2000 and ispMACH 4A families. The 'B' suffix typically denotes a 2.5V core voltage variant, while 'V' indicates the broader family characteristics including SuperFast performance. It serves as a successor to older PLD technologies, offering higher density and lower power consumption.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may be limited due to the obsolete status. Consider the LC4384V-75FT256C for similar specifications with potentially updated manufacturing processes. Evaluate the LC4512V series for increased macrocell count if future scalability is required. Verify pin-to-pin compatibility before substituting with other CPLD families.
