    Power interfaces Power supply architecture The ConnectCore 6UL requires a primary power supply input. This supply is the main power domain to the on-module NXP PF3000 power management IC (PMIC), which generates all required supply voltages for the module as well as the external interfaces. The system can be powered from voltages up to 5.5V.
  • Page 12 In the implementations shown above, the coin cell/supercapacitor is connected to VCC_LICELL pin of the ConnectCore 6UL module, allowing coin-cell charger applications. This VCC_LICELL connection feeds the VSNVS regulator of the PMIC, which supplies the SNVS power domain of the CPU.

    You must take into account the forward voltage drop of the diode for charging the coin cell. Digi has validated this hardware configuration with the Panasonic DB2J31400L diode. It's low reverse leakage current (300 nA) is ideal for this low-power mode application.

  • Page 17: Bootstrap

    R = 47 kΩ Bootstrap The ConnectCore 6UL module can be configured to boot from different devices and interfaces as determined by the Boot ROM. The configuration of the booting process of the CPU is done through: BOOT_MODE register, which selects the boot mode of the processor.

  • Page 18: Internal Boot

    However, this time the values of some registers are overridden using multiple GPIOs, which are latched during power-up. The following configuration is done internally in the ConnectCore 6UL module in order to enable booting from the NAND memory:...

  • Page 26: Micro Controller Assist

    The Micro Controller Assist, or MCA, is a small microcontroller that is deeply integrated into the design of the ConnectCore 6UL module. It assists the i.MX6UL 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 28: Reset Control

    The MCA, in cooperation with the PMIC, controls the reset line of the i.MX6UL processor (POR_B). The MCA_RESET pin is the main reset input of the ConnectCore 6UL module. This pin is a pseudo open- drain with an internal pull up. Asserting the MCA_RESET line low sets the MCA into reset state, and it remains in this state until the line is de-asserted.

  • Page 29: Ios

    MCA software documentation for additional information on the configuration of the MCA. The ConnectCore 6UL MCA provides up to eight configurable IOs. Since the general purpose IOs do not incorporate internal pull-ups or pull-downs, you may have to add the components to the exterior of the module carrier board.
  • Page 30 These ADCs are suitable for low-frequency sampling (under 10 Hz). For higher frequency sampling, Digi recommends the CPU ADC channels. You can configure the MCA ADC lines to act as an analog window comparator and generate an IRQ depending on the voltage level in the input.

  • Page 31: Watchdog

    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.

  • Page 32: Real-Time Clock

    Tamper support The tamper interface provides a mechanism to detect any unauthorized attempt to access the system, such as the opening of the enclosure. The tamper support included in the ConnectCore 6UL is implemented in the MCA with the following capabilities: Configure up to two tamper interfaces, each with an optional digital output.

  • Page 33: Power Management

    MCA I/Os. Power management The MCA plays a key role in the power management activities of the ConnectCore 6UL module. In cooperation with the i.MX6UL processor, the MCA controls the power states of the PMIC and provides multiple wake up sources to transition between power modes.
  • Page 34 About the ConnectCore® 6UL Micro Controller Assist™ 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. 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.
  • Page 35 About the ConnectCore® 6UL Micro Controller Assist™ Note that the specific state of the regulators (on/off) and the voltage in this mode are controlled by the firmware running on the i.MX6UL processor. The PMIC starts with the default settings configured on the OTP area, but once the software takes control it applies the specific configuration implemented in the firmware.

  • Page 36: Mca Firmware Update

    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.
  • Page 37 About the ConnectCore® 6UL Module pinout - general layout White cells: LGA pads Orange cells: castellated pads Note Pad A1 is unconnected. This pad is meant for module-orientation purposes; its shape is square, whereas all other pads are circular. Pad A1 should not be soldered down to a corresponding pad on the carrier board.

  • Page 38: External Signals And Pin Multiplexing

    External signals and pin multiplexing The following tables provide the pinout information of the ConnectCore 6UL module. For additional information related to the signals listed in the table, refer to the NXP i.MX6UL technical documentation. Note The Digi ConnectCore Smart IOmux tool can dramatically simplify pin configuration and resolution. You can enter the list of interfaces required by your project and use the Smart IOmux graphical interface to mock up configuration options, resulting in full pin assignment and device tree snippets that match your desired functionality.

You can also use the ConnectCore 6UL SBC Express to test VSYS supplies below 4.5V, which are typically required for battery operation. In order to facilitate this mode, ground VPWR (R115 populated and R6 depopulated) and leave LDOG unconnected (depopulate C1 and U1).

  • Page 125 Digi recommends X-ray analysis after reflow to confirm proper mounting and solder reflow. The ConnectCore 6UL module is approved to withstand a total of four (4) reflow cycles. Two (2) reflow cycles are required for manufacturing the ConnectCore 6UL module. Two (2) reflow cycles are remaining for mounting the module on the carrier board.
