3.5.6
USB 2.0 Interfaces
The TQMxE39S supports six USB 2.0 ports at the SMARC connector.
3.5.7
USB 3.0 Interfaces
The TQMxE39S supports two USB 3.0 ports at the SMARC connector.
Note: USB Port Mapping
The USB 2.0 port 0 must be paired with USB 3.0 SuperSpeed port 0.
The USB 2.0 port 1 must be paired with USB 3.0 SuperSpeed port 1.
3.5.8
SD Card Interface
The TQMxE39S provides an SD card interface for 4-bit SD/MMC cards at the SMARC connector.
3.5.9
General Purpose Input/Output
The TQMxE39S provides twelve GPIO signals at the SMARC connector.
The GPIO signals are shared with camera control, fan Control and HD Audio Reset signals. They can be configured by software.
The GPIO signals are integrated in the TQ-flexiCFG block and can be configured flexible.
Therefore the signals can also be used for several special functionality (see 3.4.6).
Please contact
for further information about the GPIO configuration and their alternate uses.
3.5.10
Audio Interface
The TQMxE39S provides a High Definition Audio (I) and an I
2
interface, which support Audio codecs at the SMARC connector. The
audio codec on the carrier board should be supported by the BIOS of the TQMxE39S.

3.5.11
MIPI CSI Camera Interface
The TQMxE39S supports two camera interfaces where 2- or 4-lane MIPI CSI cameras can be connected.
3.5.12
I
2
C Bus
The TQMxE39S supports a general purpose I
2
C bus via a dedicated LPC to I
2
C controller, integrated in the TQ-flexiCFG block.
The I
2
C host controller supports a clock frequency of up to 400 kHz and can be configured independently.
3.5.13
SMBus / Power Management I
2
C Bus
The TQMxE39S provides an I
2
C based SMBus interface. This bus is also called power management I
2
C bus.
3.5.14
Serial Peripheral Interface
The TQMxE39S provides an SPI interface. The SPI interface can only be used for SPI boot Flash devices.
