MAX II devices have an internal linear voltage regulator which supports external
supply voltages of 3.3 V or 2.5 V, regulating the supply down to the internal operating
voltage of 1.8 V. MAX IIG and MAX IIZ devices only accept 1.8 V as the external
supply voltage. MAX IIZ devices are pin-compatible with MAX IIG devices in the
100-pin Micro FineLine BGA and 256-pin Micro FineLine BGA packages. Except for
external supply voltage requirements, MAX II and MAX II G devices have identical
pin-outs and timing specifications. Table 1–5 shows the external supply voltages
supported by the MAX II family.

Notes to Table 1–5:
(1) MAX IIG and MAX IIZ devices only accept 1.8 V on their VCCINTpins. The 1.8-V VCCINT external supply powers the device core directly.
(2) MAX II devices operate internally at 1.8 V.
