Table 48 X43 Pinout Description
Pin Signal
Description
Pin Signal
Description
1
+V5S
5V main supply (0.75 A fuse)
2
+V5A
5V standby supply (0.75 A fuse)
3
SUS_CLK
Clock used by carrier board
peripherals such as M.2 cards in
their low power modes.
4
RAPID_
SHUTDOWN
Trigger for rapid shutdown. Must be driven to 5V
through a <=50 ohm source impedance for ≥ 20 µs.
Pull-down or disable on module if pin is not asserted.
5
TAMPER#
Tamper or intrusion detection line
on VCC_RTC power well. Carrier
hardware pulls this low on a
Tamper event.
6
SUS_S4_S5#
Active low output that indicates the system is in
Suspend to Disk (S4) or Soft Off (S5) state.
7
PS_ON#
ATX power supply on (active low)
8
CARRIER_HOT#
Input from off-module temperature sensor indicating
an over-temperature situation.
9
SUS_S3#
Suspend to RAM state (active low
output)
10
N.C
Not connected
11
THERMTRIP#
Active low output indicating that
the CPU has entered thermal
shutdown.
12
WAKE1#
General purpose wake up signal. It may be used
to implement wake-up on PS2 keyboard or mouse
activity.
13
WD_OUT
Output indicating that a watchdog
time-out event has occurred.
14
N.C
Not connected
15
WD_STROBE# Strobe input to watchdog timer.
16
VIN_PWROK
Power OK from main power supply. A high value
indicates that the power is good.
17
