Hi,
The document says:
"The 7 series FPGAs offer both high-performance (HP) and high-range (HR) I/O banks. The
HP I/O banks are designed to meet the performance requirements of high-speed memory
and other chip-to-chip interfaces with voltages up to 1.8V. The HR I/O banks are designed
to support a wider range of I/O standards with voltages up to 3.3V. Table 1-1 highlights
the features supported in the HP and HR I/O banks. Refer to Table 1-1 for help when
making initial decisions on I/O banks for a particular design's requirements. See the
specific device family data sheet for details on the performance and other electrical
requirements of the HP and HR I/O banks.
The 7 series FPGAs contain different combinations of HR and HP I/O banks. The 7 Series
FPGAs Overview documents the available number of each type of bank for all devices."
Did you read this?
Did you go through table 1-1?
Did you go through the device family datasheet?
What else information do you need?
(It's better to ask one elaborated question than a couple of vague questions)
