hi,
     there are the CoM-9G45  Low cost Linux Embedded SMD module, you  can view it.


CoM-9G45 is a 45x45mm low-cost SMT CPU module that integrates an Atmel
AT91SAM9G45, 64 MBytes of DDR2 RAM and Phy ethernet chip.

CoM-9G45 is a cost-effective System-on-Module (SoM) thought of to
drastically reduce the development time needed to design a low-power and
low-EMI Linux Embedded device.

The more complex hardware like CPU, RAM, Ethernet, power and EMI components
are integrated on a single SMD component in just 45x45 mm using an complex
PCB with 8 layers permitting hardware designers to create their carrier
board on simple and cheap 2 layers PCBs.

Atmel AT91SAM9G45 ARM9 CPU @ 400Mhz
64MB of DDR2 RAM
10/100 Mbit Ethernet interface
up to 2 USB 2.0 ports:
one hi-speed host
one full-speed
up to 5 serial lines
up to 2 I2C buses
up to 2 SPI buses
up to 60 GPIO lines
Power consumption: 0.3 Watt
Operative temperature range: 0-70 degress Celsius or -20 +70 degress Celsius (-E version)
Size: 45 x 45 mm
RoHS compliant
Low EMI
I/O voltage: 3.3 Volt
Pads: pitch 1.27 mm
User configurable led on board
Single power supply at 3.3 Volt
