3.2.1.10 CAN interface signals

Since i.MX6 processor includes a Flexible Controller Area Network (FlexCAN), the μQ7-A75-J module can also offer a CAN interface.

This interface is compliant to CAN specifications rel. 2.0 part B.

CAN0_TX: CAN Transmit Output for CAN Bus Channel 0. +3P3V_S electrical voltage level signal.

CAN0_RX: CAN Receive Input for CAN Bus Channel 0. +3P3V_S electrical voltage level signal.

Please consider that it is not possible to connect Qseven

board.

All of the above mentioned signals can also be used for different functionalities; please refer to the pin muxing table for more details.

3.2.1.11 Power Management signals

According to Qseven

specifications, on the golden edge finger connector there is a set of signals that are used to manage the power rails and power states. The

signals involved are:

PWGIN: Power Good Input, +5V_S tolerant active high signal. It must be driven on the carrier board to signal that power supply section is ready and stable. When

this signal is asserted, the module will begin the boot phase. The signal must be kept asserted for all the time that the module is working.

PWRBTN#: Power Button Input, active low +3.3VSB electrical voltage signal, with 10kΩ pull-up resistor. When working in ATX mode, this signal can be connected

to a momentary push-button: a pulse to GND of this signal will switch power supply On or Off.

RSTBTN#: Reset Button Input, active low +3P3V_S electrical voltage signal. This signal can be connected to a momentary push-button: a pulse to GND of this

signal will reset the Qseven

module.

SUS_S3#: S3 status output, active low +3.3VSB electrical voltage signal. This signal must be used, on the carrier board, to shut off the power supply to all the

devices that must become inactive during S3 (Suspend to RAM) power state.

SUS_S4#: S4 status output, active low +3.3VSB electrical voltage signal. This signal is used, on the carrier board, to shut off the power supply to all the devices

that must become inactive only during S4 (Suspend to Disk) power state.

WAKE#: Wake Input, active low +3.3VSB electrical voltage signal with 10kΩ pull-up resistor and series Schottky diode. This signal can be driven low, on the carrier

board, to report that a Wake-up event has occurred, and consequently the module must turn itself on. It can be left unconnected if not used. Please be aware that

this signal can also be used differently, please check the pin-muxing table.

SLP_BTN#: Sleep button Input, active low +3.3VSB electrical level signal, with 10kΩ pull-up resistor. This signal can be driven, using a pushbutton on the carrier

board, to trigger the transition of the module from Working to Sleep status, or vice versa. It can be left unconnected if not used on the carrier board. Please be

aware that this signal can also be used differently, please check the pin-muxing table.
