Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate temperature range or packaging variations. Ensure design-in documentation matches the exact part number to avoid pinout mismatches.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design logic requirements. The 1.8V supply voltage dictates the I/O voltage levels; ensure compatibility with connected components. The 25ns speed grade offers a balance between performance and power consumption compared to faster variants like the -10 or -75 series.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000C family, designed as a high-density, low-power CPLD solution. It serves as a successor to earlier GAL-based designs, offering reprogrammability and higher density while maintaining low static power consumption suitable for battery-operated applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include LC4064C-75TN100C and LC4064C-10TN100C, which offer different speed grades but identical pinouts and functionality.
