37
/ USB_P6-: USB Port #4 differential pair; it is managed by OHCI #2 and EHCI #2
internal controllers.
W_DISABLE#: Wireless Disable signal, managed by a G-Series SOC GPIO signal. It is
provided for those Wireless miniPCI-express cards able to manage the software switching
on/off.
UIM_PWR: Power line for UIM module
UIM_DATA: Bidirectional Data line between miniPCI-express card and UIM module
UIM_CLK: Clock line, output from miniPCI-express card to the UIM module.
UIM_RST: Reset signal line, sent from miniPCI-express card to the UIM module.
UIM_SPU: UIM Standard or Proprietary Use signal
Please be aware that all signals related to User Identity Modules are managed directly by the miniPCI-express card circuitry, they don
’
t involve AMD G-series
SOC
’
s management. The SBC-992-pITX board embeds only clamping diodes for ESD protection on UIM signal and voltage lines.

FAN connector
Depending on the usage model of SBC-992-pITX, for critical applications/environments on SBC-992-pITX it is available a 3-pin
dedicated connector for an ex12VDC FAN.
FAN Connector is a 3-pin single line SMT connector, type MOLEX 53261-0371 or equivalent, with pinout shown in
the table on the left.
Mating connector: MOLEX 51021-0300 receptacle with MOLEX 50079-8000 female crimp terminals.
Please be aware that the use of an external fan depends strongly on customer
’
s application/installation.
Please refer to chapter 5.1 for considerations about thermal dissipation.
FAN_POWER: +12V
IN
derived power rail for FAN, managed by AMD G-Series SOC via PWM signal
FAN_TACHO_IN: tachometric input from the fan to the G-Series SOC, +3.3V_S electrical level signal with 10k
Ω
pull-up resistor.
3.3.12
SO-DIMM DDR3 Slot
Depending on the version of the SOC used, the SBC-992-pITX board supports DDR3 memories up to 1600MHz. Please refer to Technical Specifications chapter
for a detail of memory speeds supported by each type of AMD G-Series SOC.
For use of these memories, on board there is one SO-DIMM DDR3 socket (CN2), type LOTES p/n AAA-DDR-111-K01 or equivalent, a right angle, high profile
socket, used for high speed system memory applications.
