All user I/O pins are capable of differential signalling and can implement LVDS, ULVDS, BLVDS,
LVPECL, or LDT pairs. Each user I/O is labeled “IO_LXXY_#”, where:
• IO indicates a user I/O pin.
• LXXY indicates a differential pair, with XX a unique pair in the bank and Y = P/N for the positive
• # indicates the bank number (0 through 7).
The dual-function pins are labelled “IO_LXXY_#/ZZZ”, where ZZZ can be one of the following
pins:
• Per Bank – VRP, VRN, or VREF
• Globally – GCLKX(S/P), BUSY/DOUT, INIT_B, DIN/D0 – D7, RDWR_B, or CS_B
In SelectMAP mode, D0 through D7 are configuration data pins. These pins become user I/Os
after configuration, unless the SelectMAP port is retained.
In bit-serial modes, DIN (D0) is the single-data input. This pin becomes a user I/O after
configuration.
In SelectMAP mode, this is the active-Low Chip Select signal. This pin becomes a user I/O after
configuration, unless the SelectMAP port is retained.
In SelectMAP mode, this is the active-Low Write Enable signal. This pin becomes a user I/O after
configuration, unless the SelectMAP port is retained.
In SelectMAP mode, BUSY controls the rate at which configuration data is loaded. This pin
becomes a user I/O after configuration, unless the SelectMAP port is retained.
In bit-serial modes, DOUT provides preamble and configuration data to downstream devices in a
daisy chain. This pin becomes a user I/O after configuration.
When Low, this pin indicates that the configuration memory is being cleared. When held Low, the
start of configuration is delayed. During configuration, a Low on this output indicates that a
configuration data error has occurred. This pin becomes a user I/O after configuration.
These are clock input pins that connect to Global Clock Buffers. These pins become regular user
I/Os when not needed for clocks.
This pin is for the DCI voltage reference resistor of the P transistor (per bank).
This pin is for the DCI voltage reference resistor of the N transistor (per bank).
This is the alternative pin for the DCI voltage reference resistor of the P transistor.
This is the alternative pin for the DCI voltage reference resistor of the N transistor.
These are input threshold voltage pins. They become user I/Os when an external threshold
voltage is not needed (per bank).

Each device is split into eight I/O banks to allow for flexibility
in the choice of I/O standards (see the QPro Virtex-II Data
Sheet). Global pins, including JTAG, configuration, and
power/ground pins, are listed at the end of each table.
