Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix '35' corresponds to the required 35ns speed grade against official datasheets. Check for RoHS compliance status and current production lifecycle stage, as older CPLD families may have limited availability or obsolescence notices.

Complex Programmable Logic Devices Selection Notes

Select this model when high pin count (up to 208) and moderate speed (35ns) are required in a compact 256-ball BGA footprint. Ensure the design accommodates the 1.65V-1.95V core voltage requirement. Compare against the LC4512C-5 variant if faster switching speeds are necessary, noting the trade-off between performance and potentially cost or power characteristics.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C series, a high-performance CPLD family known for low power consumption and high density. It serves as a successor to earlier GAL and EPLD technologies, offering reprogrammability and higher integration levels suitable for complex digital logic applications in industrial and communication equipment.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same family include other speed grades of the LC4512C, such as the LC4512C-5FTN256C or LC4512C-10FT256C, provided timing constraints allow for slower speeds. Verify package compatibility (FT256 vs FTBN256) and voltage requirements before substitution.
