Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T100C' against official Lattice documentation to confirm pinout compatibility and temperature grade. Ensure that the ordering information matches the exact package type and electrical specifications required for the target application. Cross-reference with authorized distributors to confirm component authenticity and availability status.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with in-system programming capabilities is required. The 75 speed grade offers a balance between performance and power consumption suitable for general-purpose logic applications. Consider the 100-pin TQFP package constraints regarding board space and thermal management during the initial design phase.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V series, designed for low-power, high-performance programmable logic solutions. The LC4256 variant provides a scalable platform for designers needing reliable, non-volatile configuration without the complexity of FPGA-based designs. It serves as a robust alternative to traditional discrete logic gates in compact form factors.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include variants with different speed grades or package options, such as the LC4256V-5TN100C. Verify that any substitute maintains the same pinout and electrical characteristics to ensure seamless integration without requiring PCB layout modifications.
