SMARC-sAMX6i / Product Specification

3.6 Power Control

Power Supply

The SMARC-sAMX6i supports a power input from 3.0-5,25V. The supply voltage is applied through the VCC pins (VCC) of the

module connector.

Power Button (PWR_BTN#)

The power button (Pin P128) is available through the module connector described in the pinout list. To start the module

via Power Button the PWRBTN# signal must be at least 50ms (50ms ≤ t < 4s, typical 400ms) at low level (Power Button

Event).

Pressing the power button for at least 4seconds will turn off power to the module (Power Button Override).

CB_POWER_BAD#

The SMARC-sAMX6i provides an external input for a Carrier Board Power Bad signal (Pin S150). The implementation of this

subsystem complies with the COM Express® Specification. CB_POWER_BAD# is internally pulled up to 3.3V and must be

high level to power on the module.

Reset Button (RST_CB_IN#)

The reset button (Pin P127) is available through the module connector described in the pinout list. The module will stay in

reset as long as RST_CB_IN# is grounded.

3.7 Power Consumption

Following data provides power consumption measurements of single modules with i.MX6 solo (51003-0540-08-1) and

i.MX6 quad (51003-1040-08-4).

processor linux shell mem test

i.MX6 solo 2.46W 3.47W

i.MX6 quad 2.87W 4.52W

This might not be the maximum load a module can have, but due to the lack of standardized stress test software for ARM

processors this data cannot be provided.
