ΣyG-S7G2 System on Module (SOM) Overview
1.1 Introduction
The ΣyG-S7G2 System on Module (SOM) provides a quick and easy solution for
implementing Renesas Synergy
TM
into a design, by providing the basic functions necessary for
a product on an easy to use SODIMM. The ΣyG-S7G2 SOM uses an industry standard 200-
pin SODIMM interface and is compatible with FDI’s ΣyG
TM
Modular Development LCD
Kits. It can also be used for custom platform development or customer applications.
1.2 ESD Warning
The ΣyG-S7G2 SOM 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 SOM requires a development kit such as the ΣyG-S7G2 Modular
Development Kit. Each yG 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
Power is supplied to the yG-S7G2 SOM through the development kit. The power
requirement for all yG development kits is 5V DC Center Positive 2A Power Supply. The power
load of the SOM is 300mA typical and 475mA max load.
ΣyG-S7G2 SOM System on Module Board Components
2.1 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.

2.3 MicroSD Socket J1
The ΣyG-S7G2 SOM utilizes a microSD for flexible mass storage. MicroSD flash cards are
common, cost effective, and provides a large amount of user-changeable memory.
Pin Number Description
1 DAT2/RSV
2 CD_DAT3/CS#
3 CMD/SDI
4 VDD
5 CLK/SCLK
6 VSS
7 DAT0/SDO
8 DAT1/RSV
9 CD
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.

2.3.1 : 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.
