I/O Standards and Voltage Levels
Stratix IV and HardCopy IV devices support different I/O counts per bank.
Therefore, always set the HardCopy IV companion device for your Stratix IV design
project in the Quartus II software. For more information, refer to Table 6–2.
Table 6–1 lists the differences between HardCopy IV GX and Stratix IV GX devices.

DPRIO settings, and MRAM size reduced to 8 kB for retry and receive buffers.
I/O Standards and Voltage Levels
HardCopy IV devices support a wide range of industry I/O standards, including
single-ended, voltage-referenced single-ended, and differential I/O standards.
Table 6–2 lists the supported I/O standards and the typical values for input and
output V_CCIO, V_CCPD, V_REF, and board V_TT.
