I/O Structure
December 2010 Altera Corporation
The 5M1270Z and 5M2210Z devices support four I/O banks, as shown in
Each of these banks support all of the LVTTL, LVCMOS, LVDS, and RSDS standards
shown in
PCI clamping diode on inputs and PCI drive compliance on outputs. You must use
Bank 3 for designs requiring PCI compliant I/O pins. The Quartus II software
automatically places I/O pins in this bank if assigned with the PCI I/O standard.

(4) Emulated LVDS output using a three resistor network (LVDS_E_3R).
(5) Emulated RSDS output using a three resistor network (RSDS_E_3R).
Each I/O bank has dedicated V
in that bank. A single device can support 1.2-V, 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 V

both the input and output buffers in MAX V devices.
The JTAG pins for MAX V devices are dedicated pins that cannot be used as regular
I/O pins. The pins TMS, TDI, TDO, and TCK support all the I/O standards shown in
Table 2–4 on page 2–29
for all MAX V devices and their I/O standard support is controlled by the V
setting for Bank 1.
