Complex Programmable Logic Devices Procurement Notes

Verify component status as this specific part number may be discontinued or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design files and programming tools before procurement. Check for RoHS compliance documentation if required by local regulations.

Complex Programmable Logic Devices Selection Notes

Select this CPLD when a moderate density solution with fast propagation delays is required. The 5 ns delay specification suits high-speed synchronous designs. Consider pin count requirements carefully, as the 144-pin package offers 96 usable I/Os. Evaluate thermal performance within the specified commercial temperature range during board layout.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V series, designed for cost-effective, low-power programmable logic solutions. The series targets applications requiring reliable, non-volatile configuration without the complexity of FPGA flows. It serves as a drop-in replacement for older GAL devices in many legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes within the same family include other speed grades or package variants of the LC4256V series, such as the LC4256V-5TN100C for smaller form factors. Verify pinout compatibility when selecting alternative packages. Cross-reference with newer Lattice families only if architectural differences are acceptable.
