Figure 9: Pin Numbering for the Module Connector
Warning!
Do not use excessive force to latch a Mercury module into the Mercury connectors on the base board,
as this could damage the module and the base board; always make sure that the module is correctly
oriented before mounting it into the base board.

Pinout

Information on the Mercury SA1 SoC module pinout can be found in the Enclustra Mercury Master Pinout
[11], and in the additional document Enclustra Module Pin Connection Guidelines [10].
Warning!
Please note that the pin types on the schematics symbol of the module connector and in the Master
Pinout document are for reference only. On the Mercury SA1 SoC module it may be possible that
the connected pins do not have the targeted functions (such as primary clocks, differential pins, MGT
signals, etc).
The naming convention for the user I/Os is:
IO_B<BANK>_<FUNCTION>_<PIN_NAME>_<PACKAGE_PIN>_<POLARITY>
For example, IO_B5A_TX_R5_AC24_P is located on pin AC24 of I/O bank 5A, and when used in a differential
pair it is a transmit pin and has positive polarity.
The clock capable pins are marked with "CLK" in the signal name. For details on their function and usage,
please refer to the Intel documentation.
Table 5 includes information related to the total number of I/Os available in each I/O bank and possible
limitations.
Please note that Cyclone V devices can only use I/O pins marked with "RX" in the signal name as differential
inputs and only pins marked with "TX" as differential outputs. The I/O pins marked with "CLK" are receive-
only differential signals and can be used as dedicated clock differential inputs. All pins can be used as
single-ended inputs or outputs.
