A block diagram of the MitySOM-5CSX Development Kit is illustrated in Figure 1 on
the following page. Control of the on-board interface hardware and connected Expansion
IO cards require proper configuration of the MitySOM-5CSX Module. While not
required, it is strongly recommended that the MitySOM software development kit and
supplied API be used to manage these interfaces.

Debug UART to USB Interface Description
MitySOM-5CSX Development Kit
6 August 2014
The on-board UART to USB Bridge, FTDI FT230X, provides a serial interface at data
rates up to 115,200 baud. The USB serial interface, J400 - Console, is routed to the
primary MitySOM serial bootloading port, UART0. It allows for general module debug,
remote code download and FLASH upgrades on an attached MitySOM from this
connector when interfaced with a PC.
When connected to a Windows XP, Vista, 7 or 8 PC no drivers are required as Windows
Update is used to obtain the drivers.
USB 2.0 Interface Description
The on-board USB OTG interface utilizes a mini B type connector J401 and interfaces
with the USB phy on the MitySOM-5CSX module. This phy is connected to the USB0
controller within the Cyclone V SoC HPS. Linux drivers are available. This interface
allows for a connection to either a PC or a USB device through the use of a USB-OTG to
USB A type adapter, not included.
MultiMedia Card (SD) Interface Description
The on-board MultiMedia Card (MMC) slot uses a Secure Digital connector J403 which
supports standard (3.3V) cards. U-Boot configuration information and Linux drivers are
available.
Gigabit Ethernet Interface Description
The on-board Ethernet interface features a Micrel KSZ9031 Ethernet PHY capable of
running at 10/100/1000Mbit including link auto-negotiation and RGMII/MDIO
capability. An industry standard RJ-45 connector is provided for external connection.
This Ethernet interface may be used to perform remote code download via U-Boot and
FLASH upgrades on an attached MitySOM-5CSX module in addition to standard
network interfacing.
SATA Interface Description
The on-board SATA connector allows for connection to the MitySOM-5CSX module
gigabit transceivers. To take advantage of the SATA interface an IP core needs to be
used. There are a number of companies that offer such cores and you can contact your
Critical Link representative for a recommendation.
RTC Battery (VBat)
The MitySOM-5CSX Development Board includes a 3V battery to power the RTC on the
module. This battery is identifier B600 and is a Panasonic BR1225-1VC. Note that if the
battery gets discharged, below 1.2V, a new battery may be required for proper module
function. If the battery voltage is between 1.2V and 1.8V a slower JTAG clock frequency
may be needed for JTAG debugging. Please contact a Critical Link representative for
details.

Full HSMC Interface Description
MitySOM-5CSX Development Kit
6 August 2014
The Full High Speed Mezzanine Card (HSMC) interface allows for the use of add-on
cards that are designed for the Altera Cyclone V on the MitySOM-5CSX module. A
number of “off the shelf” boards/kits are available from Critical Link and other third
parties that are compatible with this interface.
Full HSMC JTAG Debug Interface Description
The 10-pin JTAG header J302 is available onboard for debugging of a device that is
connected to the Full HSMC connector, J300.
Partial HSMC Interface Description
The Full High Speed Mezzanine Card (HSMC) interface allows for the use of add-on
cards that are designed for the Altera Cyclone V on the MitySOM-5CSX module. This
interface offers access to a single Gigabit transceiver interface as well.
PCI-e x4 Interface Description
The on-board 4-channel PCI-e interface provides both root port and endpoint mode
support for PCI-e x1, x2 and x4 devices when a MitySOM-5CSX is used. In addition an
on-board 100MHz clock is provided as well as +12V and +3.3V external power supplies.
Dual CAN Interface Description
The on-board CAN provides a set of CAN V2.0B compliant interfaces. These interfaces
are managed by the MitySOM-5CSX module directly.
The galvanic isolation is provided by a dedicated TI ISO1050 transceiver for each
interface. The ISO1050 is powered by an isolated power supply with 1000V* isolation
from the primary supply.
Jumpers JP400 (CAN 1) and JP401 (CAN 0) can provide dedicated bus termination of
120Ohm. To enable termination, place shorting jumper across JP504.
The electrical interfaces are provided via J404 (CAN1) and J405 (CAN0), 10-pin
shrouded headers.
Linux Driver and API examples are available to support CAN functionality.
Debug/User Switch Descriptions
A total of 5 switches are present on the 5CSX Development Kit.
S400, S401 and S402 are tied to HPS GPIO pins on the module edge connector; pins 252,
264 and 266 respectively. These switches can be utilized for any user defined functions.
S403 is for the HPS Warm Reset which just causes the MitySOM Cyclone V SoC to
perform a soft reset.
S404 is for the Cold Reset which causes the MitySOM input power supply to be toggled.
