ΣyG-S7G2 Modular Development Kit (MDK) Overview
1.1 Introduction
The Future Designs, Inc. ΣyGTM Family provides a complete and qualified Graphical User
Interface (GUI) / Human Machine Interface (HMI) platform for the rapid release of customer
products. The core of ΣyG (pronounced, “sig”) is Renesas SynergyTM – a comprehensive and
integrated software-based microcontroller platform. FDI adds the Synergy platform to its GUI
hardware, systems and production expertise. The end result is a sum of high-quality products that
provide a robust and proven source for GUI and HMI solutions:
ΣyG = Renesas Synergy+ GUI
The ΣyG-S7G2 Modular Development Kit for the System on Module is the gateway for beginning
Renesas SynergyTM projects. The ΣyG-S7G2 Modular Development Kit is compatible with FDI’s
ΣyG Modular Development LCD Kits but can be used independently as a lower cost option for those
embedded applications without the need for a touch screen display. FDI offers low cost customization
services for customer specific hardware, software or packaging applications at volumes of 500 units
or more.
1.2 ESD Warning
The ΣYG-S7G2-MDK is shipped in a protective anti-static package. Do not subject the module to
high electrostatic potentials. Exposure to high electrostatic potentials may cause damage to the
boards that will not be covered under warranty. General practice for working with static sensitive
devices should be followed when working with the kit.

1.5 Requirements
The ΣYG-S7G2-MDK requires a carrier board with a 200-pin SO-DIMM socket. The
socket should have the key at the 1.8V location. The CARRIER Board from Future Designs
provides this socket and should be utilized to develop your application for initial verification.
Each ΣyG development kit includes:
•ΣyG-S7G2 System on Module (SOM)
•Renesas Synergy Software Platform
•Carrier Board
•5 VDC, 2.3A North American Power Supply
•USB and Ethernet Cables
•Segger ARM Cortex-M Mini-JTAG debugger and cables
•Optional LCD Carrier Board
•Optional 4.3” or 7.0″ PCAP Touch Screen LCD
1.6 ΣyG-S7G2 SOM Power Requirements
The power requirement for the ΣYG-S7G2-MDK is 5V DC Center Positive 2A Power Supply.
Getting Started
2.1 Setting up the Hardware
The SOMDIMM should be inserted into the DIMM Socket as shown below and then
locked into place by pushing down to the Carrier Board. Ensure the SOMDIMM is inserted
completely into the socket prior to locking. The socket utilized on the CARRIER Board is
rated for a minimum of 25 insertions.

Page 9of 26
Figure 3: SOMDIMM Insertion
The following are step by step instructions for setting up the hardware.
1) Make sure you have a SOMDIMM board plugged into the CARRIER board at J1.
2) Verify the LCD Interface ribbon cable connects the LCD CARRIER board to the CARRIER (J7)
board.
3) With the power off, plug the 5V center-positive Power Supply into 5V (P5) of the CARRIER
board.
4) Connect an RJ-45 Ethernet cable to the ETHERNET (J5) interface of the CARRIER board.
5) Plug in a female-to-female DB9 serial cable between PC and RS232 (P4) on the CARRIER board.
6) Insert a USB drive.
2.2 Demonstration Software
Insert a formatted USB drive into the ΣYG-S7G2-MDK boards and connect them to your PC using an
Ethernet cable. In your PC, set a static IP address on the PC to be on the same network
(IP=192.168.0.x with Subnet mask=255.255.255.0). Once connected, the ΣYG-S7G2-MDK
demonstration software will deliver you to a web page at the address http://192.168.0.180. Thread
counts will automatically update or you can click on “System Variables” to force an immediate
update. Use the 7 ThreadX tasks outlined on the web page to update the system variables.

ΣyG-S7G2 SOM System on Module Board Components
4.1 ARM Mini-JTAG J2
The ΣyG-S7G2 SOM uses a JTAG connector based on a 2mm header. This smaller
connector provides 100% of the functionality of the standard 20-pin JTAG connector, but
utilizes 70% less board space.

The microSD card must be removed using the spring loaded “push-pull” mechanism on the
microSD socket. Forceful removal of a microSD card will result in permanent damage to the
socket that is not covered under warranty. To insert the card, push it into the socket until a
“click” sound is heard. Similarly, to remove the card, push the card into the socket. The push-

pull mechanism will “click” again and eject the card from the socket. The card is now
available for safe removal.
4.3.1 Inserting the microSD card into the microSD socket
First, prepare to insert the microSD card into the
socket by positioning it with its text facing up.
Position the ridge, or “lip”, of the card furthest
from the socket.
Next, partially insert the card into the socket.
Then, use your figure to gently push the card
into the socket. When the card “clicks” into
place it is in its final, locked position. The card
is now ready for use.
Note: Once the microSD card is fully inserted it
should not fall out, even if the unit is shaken
vigorously.

4.3.2 Removing the microSD card from the microSD socket
Begin to remove the microSD card by gently
pushing the card into the socket. The socket
will “click” and eject the card.
Once the microSD card is ejected, it will
partially extend out from the socket.
Carefully grab the ridged edge or sides of the
microSD card to gently pull it out.
The microSD card is now fully removed from
the socket.
4.4 Ethernet PHY U5
The ΣyG-S7G2 SOM provides an Ethernet PHY from SMSC, LAN8720. The LAN8720 is
a single chip solution for a 100BASE-TX/10BASE-T physical layer transceiver. It has support for
reduced MII (RMII), and HP MDI-X auto crossover allowing for any standard Ethernet cable to be
used, even a crossover cable. The LAN8720 is fully compliant to IEEE 802.3u with support for
auto-negotiation and manual selection of 10/100Mbps speed as well as full and half-duplex modes.
