Power supply

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. See Powering the system from a nominal 5V power supply (4.5V to 5.5V) and Powering the

system for battery-powered applications (3.7V - 4.5V) for recommended power schemes for the

ConnectCore 6UL module.

The ConnectCore 6UL module has a dedicated pin for connecting a coin cell backup battery or super capacitor. You can enable a coin cell charger on the PMIC with Li-ion rechargeable batteries. This backup battery or super capacitor is mandatory if RTC time must persist after the module has been disconnected from main power. You must also follow the recommended diode configuration as shown in the diagrams below to make sure the module holds the system time.

If RTC time retention is not required, you can remove the circuitry from your design and connect the

3.3V voltage regulator directly to the VCC_MCA and MCA_VIN_DET pins.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Power supply

Powering the system for battery-powered applications (3.7V - 4.5V)

Note 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. This power domain allows some functionality of the CPU in low power mode applications when the main power supply of the system is removed. However, this connection significantly increases the power consumption of the coin cell/supercapacitor in this low-power mode.

To optimize power management in coin cell applications:

Do not connect the coin cell/supercapacitor to the VCC_LICELL power domain (keep the connection to VCC_MCA). This removes coin-cell charger functionality but drastically reduces power consumption and extends the life of the power supply. However, this connection significantly increases the power consumption of the coin cell/supercapacitor in this low-power mode to around 350 uA.

The power architecture of the module is described in more detail below.

The PMIC generates the following power domains that are available on the module pads:

n Buck converters. Two buck regulators provide 3.3V:

l SW1A: 3V3_INT, powers several interfaces inside the module

l SW2: 3V3_EXT, free power line not used inside the module

n And another two buck regulators used for internal supply:

l SW1B: VDD_ARM_SOC_IN

l SW3: VCC_DDR3

VSYS and VSYS2 are the supply inputs to the regulators and buck converters of the PMIC. Both inputs are available on the module pads and can be connected to a single voltage input or to two different voltages on systems that require high efficiency on the power system:

n VSYS powers SW1A, SW2, LDO1 and LDO34 (shared input for LDO3 and LDO4).

n VSYS2 powers SW1B, SW3 and LDO2.

The power management IC located on the module is responsible for generating all required i.MX6UL processor supplies. Some of the I/O supplies are set on the module. See the following table:

NVCC_GPIO 3V3_INT

NVCC_SD1 3V3_INT

NVCC_UART 3V3_INT

One I/O voltage must be set externally and is left unconnected on the ConnectCore 6UL module: NVCC_ENET. See the following table for operating range of NVCC_ENET:

Power domain Min Type Max

NVCC_ENET 1.65 V 1.8/2.8/3.3 V 3.6 V

As shown in the table above, the supply has a wide operating range. In order to provide the most costeffective and flexible solution for a given use case, the supplies listed in the table must be provided by the carrier board integrating the ConnectCore 6UL module. However, PMIC 3.3V and LDO power rails are dedicated power sources for supplying i.MX6UL power domains.

For more information related to the PMIC power-up strategy, refer to section 6.3.5 of the NXP PF3000

datasheet.

System power-up sequence

When the power supply is connected to the ConnectCore 6UL module, the PMIC and the MCA are the first components to be powered up. VIN is the PMIC input power line, while VCC_MCA is the MCA input line. The MCA starts to run as soon as it is powered up, but the PMIC follows a fixed initialization process (see the NXP PF3000 Datasheet for a full description). In this initialization, the first regulator to automatically be powered on is the VDD_SNVS_3V3. Once this regulator is up, the PMIC can be switched on by controlling the PWRON pin (the on-off control line of the PMIC). This pin is controlled by the MCA. The MCA will turn on the PMIC after a user-programmable delay (by default 50 ms).

Once the PMIC is switched on, another fixed initialization process starts and the PMIC regulators are turned on following a defined sequence. Finally the CPU reset line (POR_B_CPU), which is also controlled by the MCA, is released.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Bootstrap

The following time diagram shows the power-up sequence.

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:

n BOOT_MODE register, which selects the boot mode of the processor.

n eFUSEs and/or GPIOs, which determine the boot configuration.

Four boot modes are available on the i.MX6UL processor. Selection between them is done through BOOT_MODE[1:0] bits. The bits are externally configurable on two processor IOs, whose values are latched during boot-up:

BOOT_MODE [1:0] Boot type

00 Boot from fuses

01 Serial downloader

10 Internal boot

11 Reserved

BOOT_MODE[0] and BOOT_MODE[1] are available on dedicated LGA pads on the module. However, on the castellated pads only BOOT_MODE[1] is available.

Note BOOT_MODE[0] is set to 0 internally on the module through a 100K pull-down resistor. This

means that in applications using only the castellated pads of the module, the only boot modes available are Boot from fuses and Internal boot. However, once Uboot is running, you can select a different boot mode (like serial downloader).

Boot from fuses

Boot from fuses is the recommended boot mode for production purposes. When this boot mode is selected, you must configure several parameters in order to select and configure the boot device of

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Internal boot

the system. These parameters are configured through fuses, which are burned in order to set their values. This means that the configuration is irreversible.

BOOT_CFG1 selects the boot device through BOOT_CFG1[7:4] bits:

BOOT_CFG1[7:4] Boot device

0000 NOR/OneNAND (EIM)

0001 QSPI

0011 Serial ROM (SPI)

010x SD/eSD/SDXC

011x MMC/eMMC

1xxx Raw NAND

There are many other registers that configure the different boot devices. For a complete description of the booting configuration, refer to the NXP i.MX 6UltraLite Applications Processor Reference Manual (Chapter 8: System Boot).

Internal boot

Internal boot is the recommended boot mode for development purposes. When this boot mode is selected, the selection and configuration of the booting process is done through the same registers used when booting from fuses. 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:

Bootstrap configuration Corresponding GPIO Default configuration

BOOT_CFG2[1] LCD_DATA9 100K pull-down

BOOT_CFG2[2] LCD_DATA10 100K pull-down

BOOT_CFG2[3] LCD_DATA11 100K pull-up

BOOT_CFG2[4] LCD_DATA12 100K pull-down

BOOT_CFG2[5] LCD_DATA13 100K pull-up

BOOT_CFG2[6] LCD_DATA14 100K pull-down

BOOT_CFG2[7] LCD_DATA15 100K pull-down

You must also set up BOOT_CFG1[7:0] register when booting from the internal on-module NAND when Internal boot mode is selected. It must be configured externally (outside the module) as shown in the following table:

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Serial downloader

Bootstrap configuration Corresponding GPIO Configuration

BOOT_CFG1[0] LCD_DATA0 0

BOOT_CFG1[1] LCD_DATA1 0

BOOT_CFG1[2] LCD_DATA2 0

BOOT_CFG1[3] LCD_DATA3 0

BOOT_CFG1[4] LCD_DATA4 1

BOOT_CFG1[5] LCD_DATA5 0

BOOT_CFG1[6] LCD_DATA6 0

BOOT_CFG1[7] LCD_DATA7 1

Digi recommends you use 10K pull-up and pull-down resistors to configure each line.

The BOOT_CFG1 and BOOT_CFG2 register lines are not dedicated lines of the CPU. This means that the values of these lines are latched during the power-up, but have a different functionality once the system is up and running. In this case, these lines belong to the LCD interface. In order to protect the value of these registers while the system is booting, Digi recommends you use a protection circuitry as shown in sheet 3 of 7, "Boot selection," of the ConnectCore 6UL reference designs. See

ConnectCore 6UL design files.

Serial downloader

You can use the serial downloader boot mode for device recovery. The serial downloader allows you to download a program image to the chip through a USB or UART serial connection. When any of the standard boot modes is selected but the booting process doesn’t succeed (for instance due to wrong booting device or corrupted images) the CPU automatically jumps to the serial downloader boot mode.

Wireless interfaces

The ConnectCore 6UL system-on-module combines a wireless local area network (WLAN) and Bluetooth (BT) dual solution to support IEEE802.11 a/b/g/n/ac WLAN standards and BT 4.2 enabling seamless integration of WLAN/BT and Low Energy technology. Digi also offers a non-wireless variant of the ConnectCore 6UL module.

The following sections include specifications for the wireless interfaces available on the ConnectCore 6UL module.

Antenna ports

The ConnectCore 6UL module has two antenna ports: one on the module via a dedicated U.FLconnector, and another on the LGA pads. Both antenna ports support WLAN and Bluetooth functionality. You can use the control signal RF1_INT/nEXT to select between the on-module antenna port (U.FLconnector) and the external antenna port (LGA pad). This control signal has a 10K pull-up populated on the module, which means that the on-module antenna port (U.FL connector) is active by default. Pulling RF1_INT/nEXTlow activates the external antenna port and disables the on-module antenna port.

Bluetooth

The ConnectCore 6UL module supports both Bluetooth and Bluetooth Low Energy protocols:

n Bluetooth 4.2 (BT4.2); backwards compatible with BT 1.X, 2.X + Enhanced Data Rate, BT 3.X, BT

4.0 and BT 4.1 Bluetooth class 1 and class 2 power-level transmissions

n Integrated WLAN-BT coexistence

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:

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

n Advanced power management such as power key button, wake up sources, and PMIC control

in low power.

n Peripheral extensions such as RTC, watchdog, and tamper pins.

The MCA and the i.MX6UL are connected through an I2C interface and an interrupt line. The microcontroller provides up to eight general purpose IOs that can be configured with different modes to provide functionality such as digital input/output or ADC.

The i.MX6UL can update the MCA firmware over the I2C bus. See the MCAsoftware documentation for additional information about this process.

Reset control

Asserting and de-asserting the MCA_RESET line wakes the ConnectCore 6UL module from any power mode (suspend/power off). Then, the microcontroller executes the programmed firmware.

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 opendrain 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.

During system initialization, the MCA performs the following actions:

n Asserts the PWR_ON line low for a configurable number of milliseconds (0-255 ms with a

default value of 50ms). This powers the PMIC off, switching off all regulated outputs of the

PMIC. You can disable this power cycle by setting the timer to 0.

n Asserts the PWR_ONline high to power the system on (assuming it was asserted low before).

n Keeps POR_B asserted low for a configurable number of miliseconds.

n Asserts the POR_B line high to start the execution of the firmware on the i.MX6UL processor.

The following time diagram represents the reset sequence. You can configure the reset timing. Default values are as follows:

n tr1: 50 ms

n tr2: 2 ms

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

SeeSystem power-up sequencefor more information about the power-up sequence of theConnectCore 6UL.

Note ThePOR_B line is also connected to the PMIC. The PMIC won't release this line until it is

switched on andthe entire starting sequence is finished (a few ms after the latest regulator is turned on). This means that even if the MCA releases the reset line before the PMIC is ready, the CPU won't go out of reset. This occurs on the ConnectCore 6UL module: the MCA releases the CPU reset line by putting the MPU_RESET linehigh butthere's a delay since this GPIO goes high until the POR_B_CPU line goes high. The delay occurs because the PMIC is still not completely initialized.

See the MCAsoftware documentation for additional information on the configuration of the MCA.

IOs

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.

The following table lists all available MCA IOs with capabilities and module pad:

Digital IOs

All MCA IOs can be configured as digital inputs/outputs, which are powered from the MCA_VCC power rail.

The digital outputs preserve the output value set in all operating modes, except in power off and coin cell modes where the IOs are reconfigured to high impedance state to preserve power.

Note Since the general purpose IOs do not incorporate internal pull-ups or pull-downs, you may need

to add the components to the exterior of the module carrier board.

MCA IRQs

You can configure a subset of the MCA IOs as interrupt inputs, using the MCA software to configure the active edge of the interrupt (rising, falling, or both). When one or more MCA IRQs are activated, the MCA interrupts the main processor through the corresponding IRQ line, signaling the active IRQs in the IRQ status registers.The IRQ inputs can wake the system from any low power mode (suspend or power off).

See the MCA software documentation for additional information about how to configure and access the MCA IRQ lines.

Analog to Digital Converter

You can configure up to five MCA IOs as Analog to Digital channels in addition to the ones provided by the i.MX6UL CPU. The index of the MCA ADC channels corresponds to the index of the MCA IO. This means that the ADC channel 0 corresponds to the MCA_IO0, the ADC channel 1 to the MCA_IO1, and so on.

The result of the ADC conversion for a given input voltage is inversely proportional to the reference voltage of the ADC. For the MCA ADCs, the reference voltagecorresponds to the MCA_VCC voltage. (Note that the i.MX6UL ADCs have a different reference voltage.) The MCA ADC provides 12-bit of resolution with right-justified, unsigned format output. These ADCs are suitable for low-frequency sampling(under 10 Hz). For higher frequency sampling, Digi recommends the CPU ADC channels.

See the MCAsoftware documentation for additional information about how to configure and access the MCA ADCs.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

External voltage reference

The MCA_IO2/EXT_VREF pin provides an accurate voltage reference of 1.2V that can be used to provide a reference voltage for sensors and/or analog devices (such as comparators or DACs).

When this pin is used as external reference voltage or as the internal reference of the MCA analog-todigital converter,an external capacitor of 100nF must be connectedbetween the pin and ground and as close as possible to the module pad.

The default configuration of the MCA_IO2/EXT_VREF pin is as IO. You must use software to configure the pin for external voltage reference. See the software documentation for additional information about how to control the function of this pin.

Note that the voltage reference continues normal operation in low power modes (suspend and power off). 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.

External 32KHz clock output

The MCA_IO6/CLKOUT32K pin is a 32.768 Hz square wave output that can be used as clock input by peripherals requiring a low-frequency, high-accuracy clock.

Note The default configuration of theMCA_IO6/CLKOUT32K pin is as IO. You must use software to

configure the pin as 32KHz clock output. See the MCAsoftware documentation for additional information about how to control the function of this pin.

Note that the 32KHz clock output continues normal operation in low power modes (suspend and power off). Therefore, if the 32KHz clock output 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 power consumption, and re-enable it when resuming normal operation.

Watchdog

The MCA implements a watchdog timer in its firmware. The MCA watchdog resets the system, or only the i.MX6UL CPU, if the software running on the main processor fails to execute properly and does not reset the watchdog timer on time.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

The main featuresof the MCA watchdog include:

n Configurable timeout between 1 and 255 seconds.

n Configurableto generate interrupt or system reset.

n Configurable to generate full-system reset (including the MCA itself) or CPU-only reset. Full-

system reset can include a PMIC off/on, depending on the device configuration.

See the MCAsoftware documentation for additional information about how to configure and access the watchdog timer.

Real-time clock

The MCA implements a Real-Time Clock (RTC) in its firmware. The i.MX6UL CPU internal RTCs are disabled by default because the MCA RTC is preferred due to its superior power consumption efficiency. To preserve the date during power-off, you must connect a coin cell battery following the design notes provided in the Power Supply Architecture section. You must also connect the MCA line VIN_PRESENT following the design guidelines inPower supply architecture in order to detect power loss and automatically switch to RTC mode.

The main features of the MCA RTC include:

n Date/time registers to keep the system time (backed up by the coin cell battery).

n Programmable alarm to generate and interrupt. This alarm can be used to wake the system

from low power modes (suspend and power off).

See the MCAsoftware documentation for additional information about how to configure and access the watchdog timer.

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:

n Configure up to two tamper interfaces, each with an optional digital output.

n Rely on tamper detection event in power-off and coin cell (battery backup) modes.

n Register tamper event(s) in the non-volatile memory of the MCA.

n Alert the host CPU when a tamper event occurs.

n Respond to a tamper attack with actions such as erasing a critical data partition of the flash.

Tamper pins

The ConnectCore 6UL module supports up to two tamper interfaces (tamper0 and tamper1). Each interface has an associated IO (tamper pin) used to detect the tamper event (through a voltage transition on the IO) and, optionally, an output IO (tamper output) that can be used to enable or disable peripherals, for instance to cut the power of a peripheral. The IOs of each tamper interface can be configured independently and have the following configuration options:

n The MCA IO used for tamper detection, from the available MCA IOs that are IRQ-capable.

n The active level (tampering) of the tamper input.

n The MCA IO used as tamper output, when enabled, that is activated when a tamper condition

has not been acknowledged.

n The logic level that is set in the tamper output when a tamper event occurs.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

The MCA IO table provides information about the capabilities of the MCA IO pins so you can easily identify suitable IOs to be used as tamper inputs. Any MCA IO pin can be configured as tamper output.

Tamper pin configuration

To learn ore about tamper pin configuration, see Tamper detection interface in the software documentation.

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, 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.

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.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

ON/RUN mode

The module enters the ON state after a power-on or system-reset event. In this mode, the PMIC is running at full power so all voltage regulators are generating the nominal voltage for this mode. The cpu reset line is de-asserted and the processor is running at normal speed, performing DVFS if the system was configured to do so. In this state, the PWR_ON line is asserted low, indicating that the module is ON.

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.

SUSPEND mode

The suspend mode (also known as suspend-to-ram mode) is the low-power mode that allows the module to preserve ram content. When the module enters SUSPEND, the following actions take place:

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL Micro Controller Assist™

n The processor goes into low power, disabling as much functionality as possible and keeping

active only the peripherals configured to wake the system from SUSPEND.

n The DDR memory is set to self-refresh mode to preserve its contents while reducing power

consumption.

n The PMIC goes into standby mode, configuring the regulators in the configured mode (on, off,

with a different voltage compared to ON state).

n The MCA goes into sleep mode, keeping active the peripherals that always run in low power

modes (like the RTC) and those configured to wake up the system (such as IRQs and power IO).

OFF mode

The module enters OFF mode after a power-off event. In this mode:

n The PMIC is set to the OFF state and all the voltage regulators, except VSNVS, are switched off.

n The PWR_ON line is asserted low, indicating that the module is in OFF state.

n The MCA goes into sleep mode, keeping active the peripherals that always run in low-power

modes (like the RTC) and those configured to wake up the system (such as IRQs and power IO).

COIN-CELL mode

In COIN-CELL mode, the module only powers the MCA from the coin-cell battery, leaving the rest of the module power inputs switched off. In this mode, the MCA remains in sleep mode, updating the RTC and monitoring the following events:

n Tamper events that would be registered in the NVRAM memory of the MCA and would assert

the Tamper output if enabled.

n Power in MCA_VIN_DET, which indicates that there is sufficient voltage to generate a power-

on event.

Power IO signal/Power button

The MCA provides a signal (PWR_IO) to detect external events that trigger a transition between the different power modes described in Power modes. The pin has wake-up interrupt/event capabilities, it is active low, and it does not provide an internal pull-up. (The pull-up resistor must be added externally if required.) This signal is ideal for connecting a power button or the output of a peripheral that controls the power state of the module and its transitions. The firmware provides a configurable debounce filter to improve noise immunity and filter rebounds on push buttons. When the PWR_IO signal is asserted low, one of the following events occurs:

n If the duration of the assertion is short (time configurable by the user) the system will trigger

an interrupt that, commonly, indicates the host processor that the system should enter

suspend state.

n If the low-pulse duration is long enough (again, time configurable by the user) the system will

trigger the power off interrupt, to indicate the host processor to start a transition to OFF

state.

n If the system does not enter OFF state before a configurable guard timer expires, the MCA will

automatically set the OFF state.

Digi recommends you use an external pull-up resistor of 100K to VCC_MCA in this SWD_CLK/PWR_IO line.

ConnectCore® 6UL Hardware Reference Manual

About the ConnectCore® 6UL CryptoAuthentication device

MCA_VIN_DET signal

The on-module MCA is powered from a dedicated external power rail, VCC_MCA. As recommended in the reference designs (see Power supply architecture), this power supply is provided by an external

3.3V regulator. If the system requires system time to be kept when there is no power, you must use a coin-cell battery to power the MCA while it keeps the RTC up to date in low-power mode. The MCA uses the MCA_VIN_DET input to monitor the input voltage and automatically switch to RTC mode to keep the system time and save power. Follow the design guidelines provided inPower supply architectureto apply the proper voltage to MCA_VIN_DET when there is a coin-cell battery in the system and when there is not.

MCA firmware update

The i.MX6UL processor can update the firmware of the MCA. See the MCAsoftware documentation for additional information about the MCA firmware update process.

CryptoAuthentication device

The ConnectCore 6UL module includes an Atmel CryptoAuthentication Device. This is a highly secure cryptographic co-processor with secure hardware-based key storage. It includes the following features:

n Performs high-speed public key (PKI) algorithms (ECDSA and ECDH).

n NIST standard P256 elliptic curve support.

n SHA-256 hash algorithm with HMAC option.

n 256-bit key length.

n Storage for up to 16 keys.

n Two high-endurance monotonic counters.

n Guaranteed unique 72-bit serial number.

n Internal High-quality FIPS Random Number Generator (RNG).

n 10 Kb EEPROM memory.

See the software documentation for information about supported cryptoauthentication features.
