Notes to Figure 2–23:

(2) Figure 2–23 is a graphical representation only. Refer to the pin list and the Quartus II software for exact pin locations.
Each I/O bank has dedicated VCCIOpins that determine the voltage
standard support in that bank. A single device can support 1.5-V, 1.8-V,
2.5-V, and 3.3-V interfaces; each individual bank can support a different
standard. Each I/O bank can support multiple standards with the same
VCCIO for input and output pins. For example, when VCCIO is 3.3 V, Bank 3
can support LVTTL, LVCMOS, and 3.3-V PCI. VCCIO powers both the
input and output buffers in MAX II devices.
The JTAG pins for MAX II devices are dedicated pins that cannot be used
as regular I/O pins. The pins TMS, TDI, TDO, and TCKsupport all the I/O
standards shown in Table 2–4 on page 2–33 except for PCI. These pins
reside in Bank 1 for all MAX II devices and their I/O standard support is
controlled by the VCCIO setting for Bank 1.
