Introduction
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 devices only accept 1.8 V
as an external supply voltage. 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 devices do not have an internal voltage regulator and only accept 1.8 V
on their VCCINTpins. Contact Altera for availability on these devices.
(2) MAX II devices operate internally at 1.8 V.
