Always switch the power off, and unplug the power supply unit, before handling the board and/or connecting cables or other

boards.

Avoid using metallic components - like paper clips, screws and similar - near the board when connected to a power supply, to avoid

short circuits due to unwanted contacts with other board components.

If the board has become wet, never connect it to any external power supply unit or battery.

Check carefully that all cables are correctly connected and that they are not damaged.

Whenever handling a SBC-992-pITX board, ground yourself through an anti-static wrist strap. Placement of the board on an anti-

static surface is also highly recommended.

1.4 Safety

The SBC-992-pITX board uses only extremely-low voltages.

While handling the board, please use extreme caution to avoid any kind of risk or damages to electronic components.

1.5 Electrostatic discharges

The SBC-992-pITX board, like any other electronic product, is an electrostatic sensitive device: high voltages caused by static electricity could damage some or all

the devices and/or components on-board.

1.6 RoHS compliance

The SBC-992-pITX board is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.

SBC-992-pITX

2.1 Introduction

SBC-992-pITX is a Single Board Computer in pico-ITX form factor (just 100 x 72mm) based on the newest AMD Embedded G-Series System on Chip (SOC), a

family of Dual/Quad Core x86 CPU with integrated discrete-class GPU and I/O controller on a single Chip.

Such a level of integration allows realizing a PC Desktop-like architecture in an extremely reduced space, with low power consumption and high performances.

This single chip solution include the memory controller, which gives support for up to 8GB of DDR3 SODIMM Memory, and also a high performance GPU, able to

drive up to two independent display using native interfaces available on the module: HDMI, LVDS / embedded Display Port and CRT.

Graphic section is embedded in the SOC; which offers an embedded AMD HD Radeon GPU, able to support dual independent displays using native LVDS /

embedded Display Port, CRT or HDMI interface. Any combinations of these video interfaces are supported. GPUs embedded in the SOC also support DirectX®

11.1, OpenGL® rel.4.2 and OpenCL rel. 1.2.

Further features, managed directly by the G-Series SOC and included in SBC-992-pITX board, are two SATA Channels, SDIO interface, six USB ports (two USB

3.0 and four USB 2.0), HD Audio interface and three PCI Express lanes; two PCI express lanes are then used for the implementation of up to two Gigabit Ethernet

interfaces (one of them is offered as a factory option), the other is carried out on half size miniPCI express slot. This latest slot is also connected to a mini-SIM card

slot, so that the SBC-992-pITX board can also be equipped with miniPCI-express modems.

Please refer to following chapter for a complete list of all peripherals integrated and characteristics.

s responsibility to use any passive cooling solution along with an

application-dependent cooling system, capable to ensure that the

heatspreader / heatsink temperature remains in the range above indicated.

Please also check paragraph 5.1

2.3 Electrical specifications

SBC-992-pITX needs to be supplied only with an external 12VDC ± 10% power supply, minimum 40W for basic functionalities

recommended.

This voltage can be supplied through a standard 6.3mm (internal pin, diameter 2.0 mm) Power Jack.

Internal pin is VIN power line.

2.3.1 Power available

When powering SBC-992-pITX with a PSU with characteristics greater or equal to the one described at beginning of previous paragraph, please consider well

what is the typical scenario for using the board (i.e., which peripherals will be connected)

Internal power section is able to supply a maximum of 8A@5V for external devices supplied directly by the module (i.e. USB devices, optionally SSD or SATA disks,

display).

Consider that each USB 2.0 port requires 500mA, and USB 3.0 ports need 0.9A each, so if all 6 USB ports are used, then the 5V power section would be able to

supply further 4.2A (about 21W) to other peripherals, like SATA Disk and/or LVDS display. Anyway, if all this current is needed by external peripherals, a 40W PSU

cannot supply further power tor internal circuitry of the board.

Since all the power must be supplied by an external PSU only, please balance well the typical final configuration, considering both the power consumption of the

board itself (up to 20W, depending on the SOC used and the total memory soldered onboard. In paragraph 2.3.2 are detailed current consumption for possible

different SOCs) and the power consumption of external devices.

This way it is possible to calculate preliminarily if a 40W PSU can be sufficient for system needing or if most powerful PSUs are required.

SBC-992-pITX

2.3.2 Power consumption

Using the following setup, and using all possible SOCs offered for SBC-992-pITX board, the current consumption has been measured on +12VDC VIN power line.

O.S. Windows 7 ultimate SP1

2GB DDR3 1066MHz CL7 SODIMM (Transcend p/n TS256MSK64V1U)

32GB SSD (p/n SandDisk SDSSDRC-032G) directly plugged on connector CN14.

HDMI display connected, resolution 1920x1200.

Both Network connections plugged to Gigabit Ethernet Network.

CAUTION: handling batteries incorrectly or replacing with not-approved devices may present a risk of fire or explosion.

2.3.3 RTC Battery

For the occurrences when the module is not powered with an external power supply, on board there is a cabled coin Lithium Battery to supply, with a 3V voltage,

the Real Time Clock embedded inside AMD G-Series SOC.

Battery used is a cabled CR2032-LD Lithium coin-cell battery, with a nominal capacity of 220mAh.

The battery is not rechargeable, and can be connected to the board using dedicated connector CN5 which is a 2-pin

p1.27 mm type MOLEX p/n 53398-0271 or equivalent, with pinout shown in the table on the left.

Mating connector: MOLEX 51021-0200 receptacle with MOLEX 50079-8000 female crimp terminals.

In case of exhaustion, the battery should only be replaced with devices of the same type. Always check the orientation before

inserting and make sure that they are aligned correctly and are not damaged or leaking.

Never allow the batteries to become short-circuited during handling.

Batteries supplied with SBC-992-pITX are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of

order SBC-992-pITX, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European Directive

above mentioned. Even when replacing the batteries, the disposal has to be made according to these requirements.

2.3.4 Power rails naming convention

In all the tables contained in this manual, Power rails are named with the following meaning:

_S: Switched voltages, i.e. power rails that are active only when the board is in ACPI’s S0 (Working) state. Examples: +3.3V_S, +5V_S.

_A: Always-on voltages, i.e. power rails that are active both in ACPI’s S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_A, +3.3V_A.

_U: unswitched ACPI S3 voltages, i.e. power rails that are active both in ACPI’s S0 (Working) and S3 (Standby) state. Examples: +1.5V_U

Other suffixes are used for application specific power rails, which are derived from same voltage value of voltage switched rails, if it is not differently stated (for

example, +5VHDMI is derived from +5V_S, and so on).
