3. System Components
3.1. Intel Atom CPU
The SBC-FitPC2 utilizes an Intel® Atom Z5xx series CPU.
The Intel® Atom Z5xx series processor is built on 45-nanometer process technology — the
first generation of low-power IA-32 micro-architecture specially designed for the new class
of Mobile Internet Devices (MID).
The following list provides some of the key features on this processor:
• New single-core processor for mobile devices with enhanced performance
• On die, primary 32-kB instructions cache and 24-kB write-back data cache
• 100-MHz and 133-MHz Source-Synchronous front side bus (FSB)
• Supports Hyper-Threading Technology 2-threads
• On die 512-kB, 8-way L2 cache
• Support for IA 32-bit and Intel® 64 architecture
• Intel® Virtualization Technology (Intel® VT)
• Intel® Streaming SIMD Extensions 2 and 3 (Intel® SSE2 and Intel® SSE3) and
Supplemental Streaming SIMD Extensions 3 (SSSE3) support
• Supports new CMOS FSB signaling for reduced power
• Micro-FCBGA8 packaging technologies

• New C6 Deep Power Down Technology
• L2 Dynamic Cache Sizing
• New Split-VTT support for lowest processor power state
• Advanced power management features including Enhanced Intel SpeedStep®
Technology
• Execute Disable Bit support for enhanced security
3.2. Chipset
The SBC-FitPC2 uses an Intel® System Controller Hub (Intel® SCH) US15W chipset.
The Intel® SCH chipset component of the Atom low power platform, combines
functionality normally found in separate GMCH (integrated graphics, processor interface,
memory controller) and ICH (on-board and end-user I/O expansion) components into a
single component consuming less than 2.3 W of thermal design power.
3.3. Graphics System
The SBC-FitPC2 graphics system is based on the Intel® SCH integrated graphics
controller, based on Intel® GMA500 architecture. The SBC-FitPC2 board features an
HDMI connector (J14) providing DVI output. DVI output is formed using a Chrontel
CH7307C DVI transmitter in revisions 1.2 and 1.2x.
Graphics Controller Description:
The Intel SCH provides integrated graphics (2D and 3D) and high-definition video decode
capabilities with minimal power consumption.
The highly compact IGD contains advanced shader architecture (model 3.0+) that performs
pixel shading and vertex shading within a single hardware accelerator. The processing of
pixels is deferred until they are determined to be visible, which minimizes access to
memory and improves render performance.
The Intel SCH supports full hardware acceleration of video decode standards such as
H.264, MPEG2, MPEG4, VC1, and WMV9.
3.4. Audio System
The audio system of the SBC-FitPC2 is implemented using Realtek’ ALC260 – a 2
Page 8

channel high-definition audio codec chip.
• The headphone stereo output connects to the on-board audio jack (P4). This output is
designed to drive a 8Ω - 32Ω headphone or line output.
• The line-in and microphone inputs are connected to dedicated 3.5mm audio jacks, P9
and P15 respectively.

3.5. Power System and Power Consumption
The SBC-FitPC2 is designed to work with a large range of power sources. It provides
stable system functionality with input voltage in the range of 7.5V-15V. An unregulated
power supply may be used as long as peaks of supply voltage don’t exceed the input
voltage range.
Power Modes and Power Consumption
There are three typical working modes: Off, Suspend to RAM (STR) and Full Operating
mode.
During Full Operating mode, power consumption may vary depending on both the
software installed on the system and on the CPU / system load.
Current consumption
Measuring conditions: Vin = 12V, no peripheral devices connected
Mode Min Max
Off 70mA 90mA
Suspend to RAM 70mA 100mA
Full Operating 0.45A 0.8A
Backup Power for RTC and CMOS memory
The SBC-FitPC2 implements backup power for RTC and CMOS settings. There is an onboard rechargeable Li-AL battery, 18mAh. The battery is constantly charged while the
power supply is connected. The RTC will retain system time and CMOS setting for at
least 100 days when the system is unpowered (as long as the system was connected to a
power supply for at least 24 hours prior to power-down).
It’s possible to reset CMOS data to default shorting J4B2 connector pins for several
seconds once the system is unpowered.
Power Supply for USB Devices
The SBC-FitPC2 has 6 USB ports, each one capable of providing up to 500mA. Total
power consumption from USB ports should not exceed 1.5A.

4. Peripheral Interfaces & Connectors
4.1. USB Interface (P1, P2, U11, U12)
The SBC-FitPC2 USB provides a total of 6 USB ports. The USB interface is provided
directly by Intel® SCH USB controller that implements UHCI and EHCI host controller
architecture and complies with USB 1.1 and 2.0 standards.
USB connector P2 is connected to the EHCI USB 2.0 controller only. Therefore it works
only with high-speed devices (480Mbps) such as storage devices, advanced cameras, etc.

4.2. MMC/SDIO/SD (P7)
The SBC-FitPC2 MMC/SDIO/SD interface is based on the SDIO controller of the Intel®
SCH chipset.
The controller supports MMC4.0 and SDIO1.1 specifications. MMC 4.0 transfer rates can
be up to 48 MHz with bus widths of 1 or 4 bits. SDIO 1.1 supports transfer rates of up to
24 MHz and bus widths of 1 or 4 bits.
The MMC controller signals are routed to the on-board mini-SD socket (P7).
