Q7-BT
21 SLP_BTN# (Sleep button. Low active
signal used by the ACPI operating system
to transition the system into sleep state or
to wake it up again. This signal is
triggered on falling edge.) 22 LID_BTN# (LID button. Low active signal
used by the ACPI operating system to
detect a LID switch and to bring system into
sleep state or to wake it up again. Open/
Close state may be software configurable.)
23 GND 24 GND
KEY KEY
25 GND 26 PWGIN
27 BATLOW# (Battery low input. This signal
may be driven active low by external
circuitry to signal that the system battery
is low or may be used to signal some
other external battery management
event.) 28 RSTBTN# (High active input for the Qseven
module indicates that all power rails located
on the carrier board are ready for use.)
29 S (Serial ATA channel 0,
Transmit Output differential pair.) 30 S
(Serial ATA channel 1, Transmit Output
differential pair; not available if optional
SATA SSD is installed)
31 SATA0_TX- (Serial ATA channel 0,
Transmit Output differential pair.) 32 SATA1_TX-
(Serial ATA channel 1, Transmit Output
differential pair; not available if optional
SATA SSD is installed)
33 SATA_ACT# (Serial ATA Led. Open
collector output pin driven during SATA
command activity.) 34 GND
35 S (Serial ATA channel 0,
Receive Input differential pair.) 36 S
(not available if optional SATA SSD is
installed)
37 SATA0_RX- (Serial ATA channel 0,
Receive Input differential pair.) 38 SATA1_RX-
(Serial ATA channel 1, Receive Input
differential pair; not available if optional
SATA SSD is installed)
39 GND 40 GND
41 BIOS_DISABLE# (Module BIOS disable
input signal. Pull low to disable module's
on-board BIOS. Allows off-module BIOS
implementations.) 42 SDIO_CLK# (SDIO Clock. With each cycle
of this signal a one-bit transfer on the
command and each data line occurs. This
signal has maximum frequency of 48 MHz.)
43 SDIO_CD# (SDIO Card Detect. This
signal indicates when a SDIO/MMC
card is present.) 44 SDIO_LED (SDIO LED. Used to drive an
external LED to indicate when transfers
occur on the bus.)
45 SDIO_CMD (SDIO Command/Response.
This signal is used for card initialization
and for command transfers. During
initialization mode this signal is open
drain. During command transfer this
signal is in push-pull mode.) 46 SDIO_WP (SDIO Write Protect. This signal
denotes the state of the write-protect tab on
SD cards.)
47 SDIO_PWR# (SDIO Power Enable. This
signal is used to enable the power being
supplied to a SD/MMC card device.) 48 SDIO_DAT1 (These signals operate in
push-pull mode.)
49 SDIO_DAT0 (These signals operate in
push-pull mode.)
50 SDIO_DAT3 (These signals operate in
push-pull mode.)
51 SDIO_DAT2 (These signals operate in
push-pull mode.) 52 Not Connected
53 Not Connected 54 Not Connected
