Table 9: I/O Banks
2.9.5 VCC_IO Usage
The VCC_IO voltages for the I/O banks located on the module connector are configurable by applying the
required voltage to the VCC_IO_B[x], respectively VCC_CFG_[x] pins. All VCC_IO_B[x] or VCC_CFG_[x] pins of
the same bank must be connected to the same voltage.
For compatibility with other Enclustra Mercury modules, it is recommended to use a single I/O voltage per
module connector.

If the Mercury+ XU1 SoC module is used in combination with a base board having only two module con-
nectors, the VCC_IO_B64 pin that powers I/O bank 64 is connected to the on-board generated 1.8 V supply
voltage.
2
The MGTs in bank 128 are available on the module connector only on “G1” assembly variants. On these variants, certain I/Os from
banks 65 and 66 are not routed to the module connector. Please check the assembly variants description in Section 2.9.2.
3
There are limitations on the I/Os from bank 64 routed via level shifters when VCC_IO_B64 is less than 1.2 V. Refer to Section 2.9.2
for details.
4
When using voltages lower than 1.8 V for VCC_IO_B66, the I2C bus on FPGA bank 66 is not operational (I2C on PL side is available
starting with revision 2).
5
For voltages of 3.3 V for VCC_IO_B47 and VCC_IO_B48 the tolerance range is -5% to +3%.
