MultiVolt Core  
The MAX II architecture supports the MultiVolt core feature, which allows MAX II  
devices to support multiple VCC levels on the VCCINT supply. An internal linear voltage  
regulator provides the necessary 1.8-V internal voltage supply to the device. The  
voltage regulator supports 3.3-V or 2.5-V supplies on its inputs to supply the 1.8-V  
internal voltage to the device, as shown in Figure 2–18. The voltage regulator is not  
guaranteed for voltages that are between the maximum recommended 2.5-V  
operating voltage and the minimum recommended 3.3-V operating voltage.  
The MAX IIG and MAX IIZ devices use external 1.8-V supply. The 1.8-V VCC external  
supply powers the device core directly.
