Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'ZC' indicates the 1.8V core voltage variant, distinct from the standard 3.3V 'V' series. Confirm the 'I' or 'C' temperature grade matches application requirements. Check for moisture sensitivity level (MSL 3) handling precautions during assembly. Ensure programming tools support the ispMACH 4000Z architecture.

Complex Programmable Logic Devices Selection Notes

Select this part when low power consumption is critical due to its 1.8V operation compared to 3.3V alternatives. Choose over the LC4256V series if higher operating temperatures up to 130°C are required. Consider pin compatibility with existing 100-pin TQFP footprints while noting the voltage difference.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4000Z family, designed for low-power applications. It complements the higher-voltage ispMACH 4000V series by offering reduced power dissipation suitable for battery-operated or thermally constrained environments. The 100-TQFP package provides a balance of I/O count and board space efficiency.
