Power Management - Advantech SOM-3567 User Manual

1.3.16.6 Watchdog
Supports multi-level watchdog time-out output. Provides 1-65535 level, from 100ms
to 109.22 minutes interval.
1.3.16.7 Serial port
1 ports 4-wire serial port supports 16550 UART compliance. The 4-wire include TX,
RX, CTS, and RTS signals.
There are additional 1 port 4-wires serial port leverage Qseven v2.1 MFG_NC[3:0]
reserve pins which multi-function with GPIO.
– Programmable FIFO or character mode
– 16-byte FIFO buffer on transmitter and receiver in FIFO mode
– Programmable serial-interface characteristics: 5, 6, 7, or 8-bit character
– Even, odd, or no parity bit selectable
– 1, 1.5, or 2 stop bit selectable
– Baud rate up to 115.2K
1.3.16.8 BIOS
BIOS chip is on module by default. Also allows the user to place the BIOS chip on the
carrier board with appropriate design and a pull-down to GND on BIOS_DISABLE#
pin.
Note! If system COMS is cleared, we strongly suggest to go to the BIOS setup
menu and load default settings at the first time of boot up.

Power Management

1.3.17.1 Power Supply
Supports both ATX and AT power modes. VSB is for suspend power and can be an
option if not requiring standby (suspend-to-RAM) support. RTC Battery may be an
option if keeping time/date is not required.
VCC: 5V +/- 5%
VSB: 5V +/- 5% (Suspend power)
RTC Battery Power: 2.0V – 3.3V
1.3.17.2 Power Sequence
According to Qseven R2.1 specification.
1.3.17.3 Wake Event
Various wake-up events allow the user to apply different scenarios.
 Wake-on-LAN(WOL): Wake to S0 from S3/S4/S5
 USB Wake: Wake to S0 from S3/S4
 PCIe Device Wake: depends on user inquiry and may need customized BIOS
 LPC Wake: depends on user inquiry and may need customized BIOS
1.3.17.4 Advantech S5 ECO Mode (Deep Sleep Mode)
Advantech iManager provides additional feature to allow the system to enter a very
low suspend power mode – S5 ECO mode. In this mode, the module will cut all
power including suspend and active power to the chipset and keep an on-module
controller active. Therefore, only under 50mW power will be consumed which means
the battery pack can last longer. With this mode is enabled in BIOS, the system (or
module) only allows a power button to boot rather than others such as WOL.
