2.7.6
USB 2.0 OTG Interface
i.MX6 Qseven PMIC SOM supports one USB2.0 OTG interface on Qseven Edge connector. i.MX6 CPU’s USB2.0 OTG
controller core with integrated PHY is used for OTG interface which can operate in High Speed operation (480 Mbps),
Full Speed operation (12Mbps) and Low Speed operation (1.5 Mbps). i.MX6 CPU’s OTG controller core can operate in
Host mode and Device (Peripheral) mode.
i.MX6 CPU’s USB OTG PHY output is directly connected to Qseven Edge connector USB Port1. Also USB ID input from
Qseven Edge connector is connected to i.MX6 CPU’s USB_OTG_ID for auto USB host or device detection. USB client
connect input from Qseven Edge connector is connected to i.MX6 CPU GPIO (GPIO2_25) for configuring client mode
if required.
For more details, refer Qseven Edge connector pins 91,92,93 & 95 on
2.7.7
SD/MMC Interface
i.MX6 Qseven PMIC SOM supports one SD/MMC interface port on Qseven Edge connector. i.MX6 CPU’s USDHC1
controller is used for SD/MMC interface which is fully compliant with SD Memory Card Specifications v3.0 including
high-capacity SDHC cards up to 32 GB & SDXC cards up to 2TB and SDIO Card Specification Part E1, v1.10. It supports
1-bit or 4-bit transfer mode
for SD and SDIO cards
up to UHS-I SDR104 mode (104 MB/s max).
Also i.MX6 CPU’s USDHC1 is fully compliant with Multimedia Card System Specification v4.2/4.3/4.4/4.41 including
high-capacity cards (size > 2GB). It supports 1-bit, 4-bit or 8-bit transfer mode
for MMC cards
up to 52 MHz in both
SDR and DDR modes (104 MB/s max).
i.MX6 Qseven PMIC SOM supports SDIO card detect & write protect input from Qseven Edge connector and
connected to i.MX6 GPIOs GPIO7_0 & GPIO6_11 correspondingly. It also supports SDIO power enable & Status LED
output on Qseven Edge connector and connected from i.MX6 GPIOs GPIO6_14 & GPIO6_7correspondingly.
For more details, refer Qseven Edge connector pins 42 to 55 on
2.7.8
AC’97/I2S Audio Interface
i.MX6 Qseven PMIC SOM supports one AC’97/SSI audio interface port on Qseven Edge connector. i.MX6 CPU’s
AUDMUX4 port is used for audio interface which provides a programmable interconnect device for voice, audio and
synchronous data routing between i.MX6 CPU’s SSI Controller and external audio/voice codec’s (also known as
coder-decoders). i.MX6 CPU’s SSI controller can be configured as AC’97 mode or I2S mode. AC’97 mode supports
frame rate from 8KHz to 48kHz and I2S mode supports sampling rate from 8KHz to 196KHz. Also reset output for
Codec is supported on Qseven Edge connector from i.MX6 CPU GPIO (GPIO1_11).
