3.4.9
Ultra Deep Power State Green ECO-Off
The TQMx50UC supports the ultra-deep power state Green ECO-Off. In this configuration all DC/DC power supplies on the
TQMx50UC are switched off. This results in lowest power consumption.
The Green ECO-Off mode can be configured in the uEFI BIOS setup.
To wake up the system from the Green ECO-Off mode the power button signal must be pulled low for a minimum of 100 ms.

Interfaces
3.5.1
PCI Express
The TQMx50UC supports up to four PCI Express Gen2 ports (4 PCIe (×1) or 1 PCIe (×4)) at COM Express™ connector (Port 0 – 3).
The default configuration for the PCI Express lanes is 4 (×1).
PCI Express lane configurations 1 (×1), 1 (×2), or 1 (×4), can be configured with a customized BIOS.
3.5.2
PCI Express Graphics (PEG)
The TQMx50UC supports one optional PCI Express Gen2 port at the COM Express™ connector (PEG interface, 1 × PCIe (×4)).
Since this interface is routed to PCIe port 5 lanes 0 – 3, the Ethernet PHY at PCIe port 5 lane 3 has to be removed.

TQ-Support
for further information.
3.5.3
Gigabit Ethernet
The TQMx50UC provides the Intel
®
i218 Ethernet controller with 10/100/1000 Mbps speed.
3.5.4
Serial ATA
The TQMx50UC supports four SATA Gen 3.0 (6 Gbit/s) interfaces.
The integrated SATA host controller supports AHCI mode and it also supports RAID mode. The SATA controller no longer
supports legacy IDE mode using I/O space.
The RAID capability provides high-performance RAID 0, 1, 5, and 10 functionality on up to 4 SATA ports of the SATA host
controller. Matrix RAID support is provided to allow multiple RAID levels to be combined on a single set of hard drives, such as
RAID 0 and RAID 1 on two disks. Other RAID features include hot spare support, SMART alerting, and RAID 0 auto replace.
Please contact
TQ-Support
for further information about the SATA RAID configuration.
3.5.5
Digital Display Interface
The TQMx50UC supports two Digital Display Interfaces (DDI0 and DDI1) at the COM Express™ connector DDI1 and DDI2.
The Digital Display Interface supports Display Port (DP), High Definition Multimedia Interface (HDMI) and Digital Visual Interface
(DVI). On both DDI ports the maximum display resolutions are:
•
DisplayPort 1.2a resolution up to 3840 × 2160 @ 60 Hz
•
HDMI 1.4 up to 4096 × 2304 @ 24 Hz
•
DVI up to 4096 × 2304 @ 24 Hz (HDMI without Audio)
3.5.6
LVDS Interface
The TQMx50UC supports a LVDS interface at the COM Express™ connector. The LVDS interface is provided through an on-board
eDP to LVDS bridge.
The eDP to LVDS bridge supports single or dual bus LVDS signalling with colour depths of 18 bits per pixel or 24 bits per pixel up
to 112 MHz and a resolution up to 1920 × 1200 @ 60 Hz in dual LVDS mode. The LVDS data packing can be configured either in
VESA or JEIDA format.
To support panels without EDID ROM, the eDP to LVDS bridge can emulate EDID ROM behaviour avoiding specific changes in
system video BIOS.
Please contact
TQ-Support
for further information about the LVDS configuration.
3.5.7
USB 2.0 Interfaces
The TQMx50UC supports eight USB 2.0 ports at the COM Express™ connector.
