The MAX II architecture supports the MultiVolt
allows MAX II devices to support multiple V
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
guaranteed for voltages that are between the maximum recommended
2.5-V operating voltage and the minimum recommended 3.3-V operating
voltage.
For external 1.8-V supplies, MAX IIG devices are required. The voltage
regulator on these devices is bypassed to support the 1.8-V V
supply path to the 1.8-V internal supply. Contact Altera for latest
information regarding MAX IIG devices.
