Complex Programmable Logic Devices Procurement Notes

Verify component status as obsolete before procurement planning. Confirm exact suffix specifications against official datasheets, as distributor listings may contain typos or generic descriptions. Ensure compatibility with existing design constraints regarding the FTBGA package dimensions and thermal requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring high pin counts in a compact BGA footprint. Verify that the system power budget accommodates the 1.65V–1.95V core voltage requirement. Consider the 5ns delay specification for timing closure in high-frequency applications compared to faster variants in the same family.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000C series, designed for super-fast, high-density PLD applications. The '5' indicates the 5ns speed grade, while 'FT256' denotes the 256-ball FTBGA package. It serves as a successor to earlier CPLD generations, offering improved density and lower power consumption.

Complex Programmable Logic Devices Replacement Considerations

Check for direct cross-references within the ispMACH 4000C family, such as other speed grades or package options like the LC4512C-5TN176I for different pin counts. Verify if newer Lattice FPGA families offer functional equivalents with updated availability.
