20 Power and System Management

NOTE: The gray table cells denote ground.

5 Power and System Management

5.1 SEMA Utility

Under the management of the BMC chip (Board Management Controller), the SEMA utility

(Smart Embedded Management Agent) provides system control and failure protection—count-

ing, monitoring, and measuring hardware and software events, from which the SOC can trigger

corrective commands. The optional SEMA Cloud utility not only controls local events on the

module but system client events on the IoT.

5.2 On-Board Power Supply

The on-board power supply generates all necessary voltages from the single supply voltage

range of 3V to 5.25V DC.

Externally, +5V Standby can be used instead of the on-board generated +5V Standby voltage.

5.3 System States

The following system states are supported: Suspend to RAM, Freeze, and Standby.

5.4 External Power Button

The board provides support for a power button to initiate transition from Off to On and On to Off

(hold for 4 seconds to power off.)

5.5 Reset-In Signal

The board provides support for a reset button to restart the system.

5.6 External Battery

The module supports an external RTC that is powered by a battery on the baseboard.
