Digital ground from the RMC connector host system.

Power (Output) 3.3 V 48 O

3.3 V from the RMC connector host system. The rail is always on when the main host system is not in sleep mode.

5 V 54, 60, 66, 72 O

5 V from the RMC connector host system. The rail is always on when the main host system is not in sleep mode.
FPGA_VIO<47..0> 234 O

I/O voltage for DIO<47..0>. 3.3 V or 2.5 V configurable via the CLIP wizard.
FPGA_VIO<96..48> 240 O

I/O voltage for DIO<96..48>. 3.3 V or 2.5 V configurable via the CLIP wizard.
Power (Input) VIN_FILTERED 1, 7, 14, 20 I

9 V to 30 V input to power the device through the RMC connector rather than through the front panel connector.

VBAT 236 I

This pin may be used to connect a longer life battery to the RTC on the host system. The RTC will track absolute time as long as either the main system battery or RMC battery through VBAT pin contains sufficient charge.

 O
Resets RST# 38 O

Reset that indicates that the main power is not ideal, or that the RMC connector host system has been reset.

SYS_RST# 43 I

System reset used to reset the RMC connector host system. Asserting this pin causes the RST# pin to also assert. This signal is pulled to 3.3 V with a 4.75 kΩ resistor when in Run Mode, Safe Mode, and Sleep Mode.
