    Power interfaces System-on-module power rails distribution 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 PMIC regulators are internally dedicated to powering the module, while others power external circuitry.
  • Page 13 However, RTC mode in the ConnectCore 8X is supported by the ConnectCore 8X MCA, not by the i.MX 8X. Therefore, in order to supply the RTC of the system, do not use VCC_LICELL as an input power rail. Instead, follow the configuration explained in power and coin cell charger.

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.

The following control lines can also be used externally in non-wireless variants:...

  • Page 28: The Micro Controller Assist™ Hardware

    The Micro Controller Assist, or MCA, is a small microcontroller that is deeply integrated into the design of the ConnectCore 8X module. It assists the i.MX 8X processor with advanced operations related to power management, security, and system reliability. The functionality provided by the MCA includes: Advanced power management such as power key button, wake up sources, and PMIC control in low power.

  • Page 29: 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.

    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.

    The MCA implements pulse- width modulation in its firmware. The MCA on the ConnectCore 8X system-on-module provides three PWM controllers. Each controller has several channels and each channel maps to one MCA IO pin:...

  • Page 33: Power Management

    PWM2 channels 0 and 1 are available on the castellated pads. 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.
  • Page 34 The ConnectCore 8X System-on-module The Micro Controller Assist™ hardware W4PK mode You can configure boot mode using the mca_config_tool –boot_mode option. If ‘boot on power’ (BOP) is chosen, the module will enter in ON state as soon as power is applied.
  • Page 35 The ConnectCore 8X System-on-module The Micro Controller Assist™ hardware If ‘wait for power key’ (W4PK) is chosen, the module will wait for a PWR_IO press before entering in ON state when power is applied. ON/RUN mode In this mode, the PMIC is running at full power so all voltage regulators are generating the nominal voltage for this mode.

    MCA_VIN_DET is a digital line, not analog. This means that the transition time between high and low values is crucial to optimize the time the system takes to switch to RTC mode. Digi recommends you ensure a fast discharge of this signal to allow a quick fall time.

    Reflow See the Reflow profile Reflow profile Digi recommends the following: SoM temperature below 238°C during reflow cycle. Time Above Liquidus (TAL) between 55 and 65 seconds. Use of 40AWG K-type thermal couple and M.O.L.E. or equivalent thermal profiler. ConnectCore® 8X System-on-Module Hardware Reference Manual...
  • Page 98 Digi recommends X-ray analysis after reflow to confirm proper mounting and solder reflow. The ConnectCore 8X System-on-Module is approved to withstand a total of four (4) reflow cycles. Two (2) reflow cycles are required for manufacturing the module. Two (2) reflow cycles are remaining for mounting the module on the carrier board.
