2.1 Introduction
®
The ETX-A61 is a ETX
3.0 compliant module, based on the Intel
Core SOCs with 64-bit instruction set. These SOCs embed all the features usually obtained by combination of CPU + platform Controller hubs, all in one single IC,
which allows, therefore, the system minimisation and performance optimisation. A complete list of SOCs available is detailed in the next subchapter.
All the supported SOCs offer a 64-bit Instruction set, and provide direct access to the memory. Frequencies up to 1333MHz are supported, with a maximum
capacity up to 8GB. Please notice that total amount of memory available is OS dependant, and depends also on the SOC.
®
All SOCs integrate an Intel
HD Graphics 4000 Series Controller, which offer high graphical performances, with support for Microsoft
OpenCL 1.2, OpenGL ES 2.0 and HW acceleration for video decoding of H.264, MPEG2, MVG, VC-1, VP8 and MJPEG video standards (for H.264, MPEG2 and
MVG also HW encoding is offered). This embedded GPU is able to drive two independent displays; this can be obtained by exploiting both the native CRT (VGA)
interface and the LVDS interface, which is realised through an eDP-to-LVDS bridge placed on one of the native Digital Display Interfaces available on the SOC.
For mass storage, on board it is possible to mount an optional eMMC disk. Furthermore, it is possible to connect external Hard Disk Drives by using the two native

top of the board. For this reason, since SATA channels available are only two, it is possible (as a factory option) to mount onboard one or two SATA-to-PATA
bridges. Depending on the configuration purchased, therefore, it will be possible to have modules with two SATA connectors on top, or with two PATA interfaces
on connector X4, or with one PATA interface on X4 and one SATA connector on top of the module.
The native HD Audio interface is connected to a Realtek ALC262 HD Audio Codec, so that it is possible to have analog audio channels (Stereo Output, Stereo
auxiliary input and microphone input) on ETX connector X1.
Four USB 2.0 ports are supported directly by the SOC, ad are carried out directly on connector X1.
To complete the functionalities of the module, and make it compliant to ETX specifications, there are onboard a Gigabit Ethernet Controller (Intel
which makes available the 10/100Mbps Ethernet interface, and a PCI-e-to-PCI bridge, to implement the PCI bus. Both these devices are managed by using two of
the PCI-express ports #0 and #1, respectively.
Furthermore, on the LPC bus, are placed a LPC-to-ISA bridge, used to implement the ISA bus which characterize the ETX modules, and a Nuvoton SUperI/O,
which makes available two full-modem serial ports, a parallel port shared with Floppy Disk interface, and PS/2 interface for Mouse and Keyboard.
The functionalities of this module are completed by the Real Time Clock, SM Bus, I2C Bus and the Watchdog. Please refer to following chapter for a complete list
of all peripherals integrated and characteristics.
The module has a very rugged design, since it is based on soldered down DDR3L memories, ceramic capacitors only and high quality AEC-Q200 grade-1
inductors. The possibility of having an embedded storage device, the eMMC, makes this module particularly suited for applications where vibrations can represent
a problem that must be faced.
®
The product is ETX
Rel.3.0 standard compliant, an industry standard defined specifically for COMs (computer on modules) which require ensuring support for
legacy peripherals (like those requiring ISA bus, PCI bus and/or PS/2 interface). Its definition provides the ability to make a smooth transition from legacy parallel
interfaces to the newest technologies based on serial buses available.
