External Memories
The SAM9M10 features a DDR2/LPDDR memory interface and an External Bus Interface (EBI) to permit interfacing to a wide range of external memories and to almost any kind of parallel peripheral.
The SAM9M10-EKES board is equipped with DDR2/LPDDR devices featuring 128 MB of DDR2-
SDRAM memory (Micron MT47H64M8B6-3 16Meg*8*4).
The External Bus Interface (EBI) is connected to three kinds of memory devices:
One Parallel Flash AT49SV322DT (not populated by default)
Two DDR2-SDRAM MT47H64M8B6-3
One NAND Flash MT29F2G16ABD (not populated by default) or MT29F2G08ABD (single footprint)
The chip select NCS0, NCS1 and CS3 are used for NOR Flash, DDR2-SDRAM and NAND Flash memories, respectively. Furthermore, a dedicated jumper can disconnect each of these NCS0, NCS1, and
NCS3 signals, making them available for other functions.

Board Description
Power Supplies
The SAM9M10 Board contains four regulated power supplies:
3.3 VDC Supply
1.8 VDC Supply
1.0 VDC Core Supply
1.0 VDC Core UTMI Supply, PLL
The outputs of these regulated power supplies
1
are distributed as necessary to each part of the circuit board.
The 3.3 VDC Supply is generated by an LTC1765-3.3 chip. It accepts VIN 5 VCC power and outputs a regulated +3.3 V to most other circuits in the SAM9M10-VB.
The 1.8 VDC Supply (VDDIOM0, VDDIOM1) is generated by an LT1765-1.8. It is powered by VIN
5 VCC power and outputs a regulated +1.8V.
The 1.0 VDC Core Supply (VDDCORE) is generated by a TPS60500 IC. It is powered by the VIN
5 VCC power.
The 1.0 VDC Core Supply (VDDUTMIC, VDDPLLUTMI and VDDPLLA) is generated by a CMOS voltage regulator R1100D series. It is powered by the output of the 3.3 VDC Supply.
Note: 1.
Corresponding test points (TP1 to TP4, GND) are used with jumpers (JP1.1 to JP7) to permit probing of these voltages.

Ethernet 10/100 (EMAC) Port
The port is compatible with IEEE
®
Standard 802.3.
The SAM9M10-EKES is equipped with a Davicom DM9161AEP 10/100 Mbps Fast Ethernet Physical
Layer TX/FX Single Chip Transceiver. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE 802.3u, including the Physical Coding Sublayer (PCS), Physical Medium attachment
(PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10BASE-TX Encoder/Decoder
(ENC/DEC), and Twisted Pair Media Access Unit (TPMAU).
The Ethernet interface integrates an RJ45 connector with an embedded transformer, and three status
LEDs.
The Ethernet interface provides two selectable modes, MII or RMII (Reduced MII), for 100Base-Tx or
10Base-Tx. The MII and RMII interfaces are capable of both 10Mb/s and 100Mb/s data rates as described in the IEEE 802.3u standard. The signals used by MII and RMII interfaces are described in the table below.

Two Wire Interface (TWI)
The SAM9M10 has a full speed (400 kHz) master/slave I2C Serial Controller. The controller is fully compatible with the industry standard I2C and SMBus Interfaces. This port is used to interface with the onboard Serial DataFlash, ISI and TV encoder interface.

SD/MMC Interface
The SAM9M10-EKES has two high-speed 8-bit multimedia interfaces MMC/MMCPlus v4.1. The first interface is used as an 8-bit interface (MCI1), connected to a CE-ATA connector footprint and an 8-bit
SD/MMC card slot. The second interface is used as a 4-bit interface (MCI0), connected to a 4-bit
SD/MMC card slot.
The users must provide their own compatible cards for use with these connectors.
Please note that the power is connected to VCC, which is 3.3 volts.

TFT LCD with Touch Panel
The SAM9M10 features an LCD controller. A 4.3" 480x272 Portrait Mode LCD provides the SAM9M10-
EKES with a low power LCD display, back light unit and a touch panel, similar to that used on commercial PDAs.
The TFT LCD component is an LG
®
/PHILIPS
®
, model number LB043WQ1.
Graphics and text can be displayed on the dot matrix panel with up to 16 million colors by supplying 24bit data signals (8bitxRGB by default) or 16-bit data signals (5+6+5bitxRGB in option). This allows the user to develop graphical user interfaces for a wide variety of end applications.
Warning: never connect/disconnect the LCD display from the board while the power supply is on. Doing so may damage both units and is not covered by warranty.
The back light voltage is generated from a TPS61161 boost converter. It is powered directly by the VIN
5 VCC power (the control for the back light voltages is separated from the main board voltages due to the specific voltage requirements of the LCD panel).

Push Buttons
The SAM9M10-EKES is equipped with two system push buttons, two user push buttons and one joystick. The push buttons consist of momentary push button switches mounted directly to the board. When any switch is depressed, a low (zero) appears at the associated input pin.
System push buttons:
– Reset, perform system reset
– Wakeup, perform system wake up
User push button:
– Right click
– Left click
Joystick:
– One touch, 5-way switching,
– Normally open momentary contacts,
– Push down to select in any position.

Expansion Slot
GPIO1 & GPIO2, LCD signals (PIO E) are routed to the connectors extension J23
All I/Os of the SAM9M10 Image Sensor Interface are routed to connectors J17
Touch screen signals and analog I/O are connected to J18
This allows the developer to extend the features of the board by adding external hardware components or boards.
