Interfaces 17
Q7-BT
3.7 USB Ports
The USB interface provides five USB 2.0 host ports, one USB 2.0 client port, and one USB 3.0
host port.
3.8 SATA
The SATA interface provides two ports through the SATA0 and SATA1 pins on the Q7-BT con-
nector. The interface supports 1.5Gb/s and 3.0Gb/s. One of the SATA ports is shared with the
PCIe Mini Card socket on the baseboard.
3.9 I2C Bus
The Q7-BT provides two interfaces through the I2C bus for General Purpose and LCD video
with operating speeds up to 400kHz. All I2C interfaces have 3.3V pull ups with 2.2k resistors.
3.10 SPI
The CPU implements an SPI controller, which supports two SPI Flash devices on the module for
BIOS storage.
3.11 Serial (UART)
The Q7-BT provides one serial interface: one high-speed, 4-wire port with TX/RX and RTS#/
CTS# signals.
3.12 SD/SDIO Interface
Four parallel data lines comprise the SD/SDIO interface, supporting SD Card sockets.
3.13 eMMC Interface
The Q7-BT provides one 8-bit eMMC interface port, brought out from the CPU through the SDIO
pins on the Qseven connector. If the optional eMMC NAND chip is present on the module, the
eMMC interface will not be available for the baseboard on the Qseven connector.
3.14 LPC Debug Interface
A 40-pin, front flip, DB40 connector allows access to the system to debug and update the BIOS,
BMC, and OS code. (Refer to “Debug (DB40) Connector Signals” on page 25.)
3.15 MIPI CSI Camera Interface
A 40-pin, board-to-FPC connector provides MCSI signals for MIPI CSI camera devices. (Refer
to “MIPI CSI Camera Connector Signals” on page 26.)
For the USB 3.0 port to support a full super-speed
connector, it must use one of the USB 2.0 host
ports, leaving four 2.0 ports available.
