    Power interfaces System-on-Module input power supply The ConnectCore 8X requires three primary power supply inputs: VSYS, VSYS2, and VCC_MCA: VSYS and VSYS2 are the input power supplies to the on-module NXP PF8100 Power Management IC (PMIC), as well as to most of its regulators. Some of the PMIC regulators are internally dedicated to powering the module, while others power external circuitry.

For those regulators that are used internally in the SOM, the current available outside it will be lower. Turn-on time for this regulator is specified for VSW7 = 1.8 V. In the ConnectCore 8X this regulator is configured to work at 3.3V, so a higher turn-on time may be observed.

  • Page 30: Reset Control

    The MCA, in cooperation with the PMIC, controls the reset line of the i.MX 8X processor. The SYS_ RESET pin is the main reset input of the ConnectCore 8X module. This pin is a pseudo open-drain with an internal pull up. Asserting the SYS_RESET line low sets the MCA into reset state, and it remains in this state until the line is de-asserted.

    8X. The ConnectCore 8X MCA provides up to 20 configurable IOs. Because the general purpose IOs do not incorporate internal pull-ups or pull-downs, you may have to add the components to the module carrier board.
  • Page 32 Therefore, if the voltage reference is enabled during normal operation but is not required for low power operation, Digi recommends using the software to disable it before entering low power in order to minimize the power consumption, and re-enable it when resuming normal operation.

    Power management The MCA plays a key role in the power management activities of the ConnectCore 8X module. In cooperation with the i.MX 8X processor, the MCA controls the power states of the PMIC and provides multiple wake up sources to transition between power modes. It also allocates dedicated signals to capture power events and indicate the system power state, allowing you to control external power sources and indicators.
  • Page 34 The ConnectCore 8X System-on-Module The Micro Controller Assist™ hardware Power modes The module provides four different power operating modes: ON/RUN, OFF, SUSPEND, and COIN-CELL. The following figure shows the state diagram and the events to switch between states. ON/RUN mode The module enters the ON state after a power-on or system-reset event.
