SBC-C90

1.4 Safety

The SBC-C90 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-C90 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-C90 board is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.

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-C90 board, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static

surface is also highly recommended.

2.1 Introduction

SBC-C90 is a Single Board Computer in 3.5’’ form factor (146 x 102mm) based on the AMD Ryzen Embedded R1000 / V1000 family of System-on-Chips (SOCs),

a series of multicore CPUs with a powerful mobile GPU - AMD Radeon Vega 11, AMD Radeon Vega 8 or AMD Radeon Vega 3 Graphics.

The SBC-C90 can mount a Dual-Core Quad-Thread or a Quad-Core eight-thread SoCs, base frequency up to 3.35 GHz (Turbo boost 3.8 GHz), with 64-bit

instruction set. This single chip solution includes the memory controller, which gives support for up to 32GB of DDR4-2400 MT/s memory on two SO-DIMM Slots,

also capable of supporting ECC memory.

All SoCs embed an AMD Radeon Vega Graphics controller, with up to 11 Execution units, which offers extremely high graphical performances, supporting also

High Dynamical range (HDR) Imaging. DirectX® 12, EGL 1.4, OpenCL 2.1, OpenGL® ES 1.1/ 2.x / 3.x (Halti), OpenGL® Next (Vulkan®), OpenGL® 4.6 are also

supported by this GPU, which can also offer H.265 10-bit video decoding and 8-bit encoding.

Finally, this embedded GPU is able to drive four 4K independent displays, by using the 4x DP++ interfaces available (3 with R1000 SoCs).

Mass Storage capabilities of the board include two external S-ATA Gen3 channels (available on two standard SATA 7p Male connectors). In addition, SBC-C90

offers an M.2 Key M Slot, which allows the plugging of M.2 High Capacity SSD drives with PCI-e x4 interface. Finally, a microSD Card slot is available for a standard

4-bit SD interface.

Networking capabilities of the board include up to two Gigabit Ethernet ports, available on 2x RJ-45 connectors, one WWAN M.2 Socket 2 Key B Slot connected to

a miniSIM card slot for modems and one M.2 Socket 1 Key E Slot for WiFi+BT M.2 modules.

Further features usable on SBC-C90 board are four USB ports (two USB 3.0 and two USB 2.0 only), HD Audio, 2x RS-232/RS-422/RS-485 UARTS, 8 x GPI/Os,

2x I2C, one Antitamper connector, and optional TPM 1.2 or 2.0 on board.

The board is available both in commercial and in industrial temperature range.

2.3.2 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 the SoC.

Battery used is a cabled CR2032S-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 CN31 which is a 2-pin

p1.27 mm type HR p/n A1250WRA-S-02PNLNG1G00R or equivalent, with pinout shown in the table on the left.

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-C90 are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of order

SBC-C90, 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.

2.3.3 Power rails naming convention

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

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

_ALW: 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_ALW, +3.3V_ALW.

_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_RUN, and so on).
