• State machine implementation in industrial control systems

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant in available records. Confirm lead times and availability through authorized distributors, noting that specific stock levels vary by region. Ensure the ordering suffix matches the required package type and temperature grade.

Complex Programmable Logic Devices Selection Notes

Select this part when a 208-pin PQFP package is required for legacy board designs. Compare against FTBGA variants if space constraints allow for smaller footprints. Verify that the 12 ns delay meets the timing requirements of the target application circuit.

Complex Programmable Logic Devices Part Context

This component belongs to the XCR3256XL family, which provides high-density logic in compact packages. It serves as a drop-in replacement for older GALs and PALs in existing designs, offering reprogrammability without significant PCB layout changes.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited due to the specific PQFP-208 package. Consider XC2C256 or LC4256V series devices only if package adaptation or redesign is feasible.
