The signal names are listed in alphabetical order. The package contact assignments can be found in Section 6, Package information and contact assignments. Signal descriptions are provided in the i.MX RT1020 Reference Manual (IMXRT1020RM). Table 4. Special signal considerations Signal name Remarks DCDC_PSWITCH PAD is in DCDC_IN domain and connected the ground to bypass DCDC. To enable DCDC function, assert to DCDC_IN with at least 1ms delay for DCDC_IN rising edge. RTC_XTALI/RTC_XTALO If the user wishes to configure RTC_XTALI and RTC_XTALO as an RTC oscillator, a 32.768 kHz crystal, (100 k ESR, 10 pF load) should be connected between RTC_XTALI and RTC_XTALO. Keep in mind the capacitors implemented on either side of the crystal are about twice the crystal load capacitor. To hit the exact oscillation frequency, the board capacitors need to be reduced to account for board and chip parasitics. The integrated oscillation amplifier is self biasing, but relatively weak. Care must be taken to limit parasitic leakage from RTC_XTALI and RTC_XTALO to either power or ground (>100 M). This will debias the amplifier and cause a reduction of startup margin. Typically RTC_XTALI and RTC_XTALO should bias to approximately 0.5 V. If it is desired to feed an external low frequency clock into RTC_XTALI the RTC_XTALO pin must remain unconnected or driven with a complimentary signal. The logic level of this forcing clock should not exceed VDD_SNVS_CAP level and the frequency should be <100 kHz under typical conditions. In case when high accuracy real time clock are not required system may use internal low frequency ring oscillator. It is recommended to connect RTC_XTALI to GND and keep RTC_XTALO unconnected. XTALI/XTALO A 24.0 MHz crystal should be connected between XTALI and XTALO. External load capacitance value depends on the typical load capacitance of crystal used and PCB design. The crystal must be rated for a maximum drive level of 250 W. An ESR (equivalent series resistance) of typical 80 is recommended. NXP SDK software requires 24 MHz on XTALI/XTALO. The crystal can be eliminated if an external 24 MHz oscillator is available in the system. In this case, XTALO must be directly driven by the external oscillator and XTALI mounted with 18 pF capacitor. The logic level of this forcing clock cannot exceed NVCC_PLL level. If this clock is used as a reference for USB, then there are strict frequency tolerance and jitter requirements. See OSC24M chapter and relevant interface specifications chapters for details. GPANAIO This signal is reserved for NXP manufacturing use only. This output must remain unconnected. JTAG_nnnn The JTAG interface is summarized in Table 5. Use of external resistors is unnecessary. However, if external resistors are used, the user must ensure that the on-chip pull-up/down configuration is followed. For example, do not use an external pull down on an input that has on-chip pull-up. JTAG_TDO is configured with a keeper circuit such that the non-connected condition is eliminated if an external pull resistor is not present. An external pull resistor on JTAG_TDO is detrimental and should be avoided. JTAG_MOD is referenced as SJC_MOD in the i.MX RT1020 reference manual. Both names refer to the same signal. JTAG_MOD must be externally connected to GND for normal operation. Termination to GND through an external pull-down resistor (such as 1 k) is allowed. JTAG_MOD set to hi configures the JTAG interface to mode compliant with IEEE1149.1 standard. JTAG_MOD set to low configures the JTAG interface for common SW debug adding all the system TAPs to the chain. NC These signals are No Connect (NC) and should be disconnected by the user. i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 NXP Semiconductors 15 Modules list Table 4. Special signal considerations (continued) Signal name Remarks POR_B This cold reset negative logic input resets all modules and logic in the IC. May be used in addition to internally generated power on reset signal (logical AND, both internal and external signals are considered active low). ONOFF ONOFF can be configured in debounce, off to on time, and max time-out configurations. The debounce and off to on time configurations supports 0, 50, 100 and 500 ms. Debounce is used to generate the power off interrupt. While in the ON state, if ONOFF button is pressed longer than the debounce time, the power off interrupt is generated. Off to on time supports the time it takes to request power on after a configured button press time has been reached. While in the OFF state, if ONOFF button is pressed longer than the off to on time, the state will transition from OFF to ON. Max time-out configuration supports 5, 10, 15 seconds and disable. Max time-out configuration supports the time it takes to request power down after ONOFF button has been pressed for the defined time. TEST_MODE TEST_MODE is for NXP factory use. The user must tie this pin directly to GND. WAKEUP A GPIO powered by SNVS domain power supply which can be configured as wakeup source in SNVS mode. Table 5.

The RTC_XTALI is used for low-frequency functions. It supplies the clock for wake-up circuit, power-down real time clock operation, and slow system and watch-dog counters. The clock input can be connected to either external oscillator or a crystal using internal oscillator amplifier. Additionally, there is an internal ring oscillator, which can be used instead of the RTC_XTALI if accuracy is not important. The system clock input XTALI is used to generate the main system clock. It supplies the PLLs and other peripherals. The system clock input can be connected to either external oscillator or a crystal using internal oscillator amplifier. Table 12 shows the interface frequency requirements. Table 12.

After crystal oscillator is stable, the clock circuit switches over to the crystal oscillator automatically. -- Higher accuracy than ring oscillator -- If no external crystal is present, then the ring oscillator is utilized The decision of choosing a clock source should be taken based on real-time clock use and precision time-out. i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 NXP Semiconductors 21 Electrical characteristics 4.1.5 Maximum supply currents The data shown in Table 13 represent a use case designed specifically to show the maximum current consumption possible.

Any deviation from these sequences may result in the following situations: * Excessive current during power-up phase * Prevention of the device from booting * Irreversible damage to the processor (worst-case scenario) 4.2.1.1 Power-up sequence The below restrictions must be followed: * VDD_SNVS_IN supply must be turned on before any other power supply or be connected (shorted) with VDD_HIGH_IN supply. * If a coin cell is used to power VDD_SNVS_IN, then ensure that it is connected before any other supply is switched on. * When internal DCDC is enabled, external delay circuit is required to delay the "DCDC_PSWITCH" signal 1 ms after DCDC_IN is stable. * POR_B should be held low during the entire power up sequence. NOTE The POR_B input (if used) must be immediately asserted at power-up and remain asserted until after the last power rail reaches its working voltage. In the absence of an external reset feeding the POR_B input, the internal POR module takes control. See the i.MX RT1020 Reference Manual (IMXRT1020RM) for further details and to ensure that all necessary requirements are being met. NOTE Need to ensure that there is no back voltage (leakage) from any supply on the board towards the 3.3 V supply (for example, from the external components that use both the 1.8 V and 3.3 V supplies). NOTE USB_OTG1_VBUS, USB_OTG2_VBUS, and VDDA_ADC_3P3 are not part of the power supply sequence and may be powered at any time. i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 24 NXP Semiconductors Electrical characteristics 4.2.1.2 Power-down sequence The following restrictions must be followed: * VDD_SNVS_IN supply must be turned off after any other power supply or be connected (shorted) with VDD_HIGH_IN supply. * If a coin cell is used to power VDD_SNVS_IN, then ensure that it is removed after any other supply is switched off. 4.2.1.3 Power supplies usage All I/O pins should not be externally driven while the I/O power supply for the pin (NVCC_xxx) is OFF. This can cause internal latch-up and malfunctions due to reverse current flows. For information about I/O power supply of each pin, see "Power Rail" columns in pin list tables of Section 6, Package information and contact assignments. 4.2.2 Integrated LDO voltage regulator parameters Various internal supplies can be powered ON from internal LDO voltage regulators. All the supply pins named *_CAP must be connected to external capacitors. The on-board LDOs are intended for internal use only and should not be used to power any external circuitry. See the i.MX RT1020 Reference Manual (IMXRT1020RM) for details on the power tree scheme. NOTE The *_CAP signals should not be powered externally. These signals are intended for internal LDO operation only. 4.2.2.1 Digital regulators (LDO_SNVS) There are one digital LDO regulator ("Digital", because of the logic loads that they drive, not because of their construction). The advantages of the regulator is to reduce the input supply variation because of its input supply ripple rejection and its on-die trimming. This translates into more stable voltage for the on-chip logics. The regulator has two basic modes: * Power Gate. The regulation FET is switched fully off limiting the current draw from the supply. The analog part of the regulator is powered down here limiting the power consumption. * Analog regulation mode. The regulation FET is controlled such that the output voltage of the regulator equals the programmed target voltage. The target voltage is fully programmable in 25 mV steps. For additional information, see the i.MX RT1020 Reference Manual (IMXRT1020RM). i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 NXP Semiconductors 25 Electrical characteristics 4.2.2.2 4.2.2.2.1 Regulators for analog modules LDO_1P1 The LDO_1P1 regulator implements a programmable linear-regulator function from VDD_HIGH_IN (see Table 11 for minimum and maximum input requirements). Typical Programming Operating Range is 1.0 V to 1.2 V with the nominal default setting as 1.1 V. The LDO_1P1 supplies the USB Phy, and PLLs. A programmable brown-out detector is included in the regulator that can be used by the system to determine when the load capability of the regulator is being exceeded to take the necessary steps. Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed. Active-pull-down can also be enabled for systems requiring this feature. For information on external capacitor requirements for this regulator, see the Hardware Development Guide for i.MX RT1020 Crossover Processors (IMXRT1020HDG). For additional information, see the i.MX RT1020 Reference Manual (IMXRT1020RM). 4.2.2.2.2 LDO_2P5 The LDO_2P5 module implements a programmable linear-regulator function from VDD_HIGH_IN (see Table 11 for minimum and maximum input requirements). Typical Programming Operating Range is 2.25 V to 2.75 V with the nominal default setting as 2.5 V. LDO_2P5 supplies the USB PHY, E-fuse module, and PLLs. A programmable brown-out detector is included in the regulator that can be used by the system to determine when the load capability of the regulator is being exceeded, to take the necessary steps. Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed. Active-pull-down can also be enabled for systems requiring this feature. An alternate self-biased low-precision weak-regulator is included that can be enabled for applications needing to keep the output voltage alive during low-power modes where the main regulator driver and its associated global bandgap reference module are disabled. The output of the weak-regulator is not programmable and is a function of the input supply as well as the load current. Typically, with a 3 V input supply the weak-regulator output is 2.525 V and its output impedance is approximately 40 . For information on external capacitor requirements for this regulator, see the Hardware Development Guide for i.MX RT1020 Crossover Processors (IMXRT1020HDG). For additional information, see the i.MX RT1020 Reference Manual (IMXRT1020RM). 4.2.2.2.3 LDO_USB The LDO_USB module implements a programmable linear-regulator function from the USB VUSB voltages (4.4 V-5.5 V) to produce a nominal 3.0 V output voltage. A programmable brown-out detector is included in the regulator that can be used by the system to determine when the load capability of the regulator is being exceeded, to take the necessary steps. This regulator has a built in power-mux that allows the user to select to run the regulator from either USB VBUS supply, when both are present. If only one of the USB VBUS voltages is present, then, the regulator automatically selects this supply. Current limit is also included to help the system meet in-rush current targets. For information on external capacitor requirements for this regulator, see the Hardware Development Guide for i.MX RT1020 Crossover Processors (IMXRT1020HDG). i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 26 NXP Semiconductors Electrical characteristics For additional information, see the i.MX RT1020 Reference Manual (IMXRT1020RM). 4.2.2.2.4 DCDC DCDC can be configured to operate on power-save mode when the load current is less than 50 mA. During the power-save mode, the converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current to maintain high efficiency. DCDC can detect the peak current in the P-channel switch. When the peak current exceeds the threshold, DCDC will give an alert signal, and the threshold can be configured. By this way, DCDC can roughly detect the current loading. DCDC also includes the following protection functions: * Over current protection. In run mode, DCDC shuts down when detecting abnormal large current in the P-type power switch. In power save mode, DCDC stop charging inductor when detecting large current in the P-type power switch. The threshold is also different in run mode and in power save mode: the former is 1 A-2A, and the latter is 200 mA-250 mA. * Over voltage protection. DCDC shuts down when detecting the output voltage is too high. * Low voltage detection. DCDC shuts down when detecting the input voltage is too low. For additional information, see the i.MX RT1020 Reference Manual (IMXRT1020RM). 4.2.3 PLL's electrical characteristics This section provides PLL electrical characteristics. 4.2.3.1 Audio/Video PLL's electrical parameters Table 16.

The oscillator is powered from NVCC_PLL. The system crystal oscillator consists of a Pierce-type structure running off the digital supply. A straight forward biased-inverter implementation is used. 4.2.4.2 OSC32K This block implements an amplifier that when combined with a suitable quartz crystal and external load capacitors implement a low power oscillator. It also implements a power mux such that it can be powered from either a ~3 V backup battery (VDD_SNVS_IN) or VDD_HIGH_IN such as the oscillator consumes power from VDD_HIGH_IN when that supply is available and transitions to the backup battery when VDD_HIGH_IN is lost. In addition, if the clock monitor determines that the OSC32K is not present, then the source of the 32 K will automatically switch to a crude internal ring oscillator. The frequency range of this block is approximately 10-45 kHz. It highly depends on the process, voltage, and temperature. The OSC32k runs from VDD_SNVS_CAP supply, which comes from the VDD_HIGH_IN/VDD_SNVS_IN. The target battery is a ~3 V coin cell. Proper choice of coin cell type is necessary for chosen VDD_HIGH_IN range. Appropriate series resistor (Rs) must be used when connecting the coin cell. Rs depends on the charge current limit that depends on the chosen coin cell. For example, for Panasonic ML621: i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 28 NXP Semiconductors Electrical characteristics * * Average Discharge Voltage is 2.5 V Maximum Charge Current is 0.6 mA For a charge voltage of 3.2 V, Rs = (3.2-2.5)/0.6 m = 1.17 k. Table 20. OSC32K main characteristics Min Fosc -- Typ Max Comments 32.768 KHz -- This frequency is nominal and determined mainly by the crystal selected. 32.0 K would work as well. Current consumption -- 4 A -- The 4 A is the consumption of the oscillator alone (OSC32k). Total supply consumption will depend on what the digital portion of the RTC consumes. The ring oscillator consumes 1 A when ring oscillator is inactive, 20 A when the ring oscillator is running. Another 1.5 A is drawn from vdd_rtc in the power_detect block. So, the total current is 6.5 A on vdd_rtc when the ring oscillator is not running. Bias resistor -- 14 M -- This integrated bias resistor sets the amplifier into a high gain state. Any leakage through the ESD network, external board leakage, or even a scope probe that is significant relative to this value will debias the amp. The debiasing will result in low gain, and will impact the circuit's ability to start up and maintain oscillations. Cload -- 10 pF -- Usually crystals can be purchased tuned for different Cloads. This Cload value is typically 1/2 of the capacitances realized on the PCB on either side of the quartz. A higher Cload will decrease oscillation margin, but increases current oscillating through the crystal. ESR -- 50 k 100 k Equivalent series resistance of the crystal. Choosing a crystal with a higher value will decrease the oscillating margin. 4.3 I/O parameters Crystal Properties This section provide parameters on I/O interfaces. 4.3.1 I/O DC parameters This section includes the DC parameters of the following I/O types: * XTALI and RTC_XTALI (Clock Inputs) DC Parameters * General Purpose I/O (GPIO) NOTE The term `NVCC_XXXX' in this section refers to the associated supply rail of an input or output. i.MX RT1020 Crossover Processors for Industrial Products, Rev. 0.1, 07/2018 NXP Semiconductors 29 Electrical characteristics Figure 3.

Overshoot/ undershoot must be controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other methods. Non-compliance to this specification may affect device reliability or cause permanent damage to the device. 2 To maintain a valid level, the transition edge of the input must sustain a constant slew rate (monotonic) from the current DC level through to the target DC level, Vil or Vih. Monotonic input transition time is from 0.1 ns to 1 s. 3 Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled. 4.3.2 I/O AC parameters This section includes the AC parameters of the following I/O types: * General Purpose I/O (GPIO) Figure 4 shows load circuit for output, and Figure 5 show the output transition time waveform.

If the polarity of the clock and/or the frame sync have been inverted, all the timings remain valid by inverting the clock signal (SAI_BCLK) and/or the frame sync (SAI_FS) shown in the figures below.

Several input pins are also sampled at reset and can be used to override fuse values, depending on the value of BT_FUSE_SEL fuse. The boot option pins are in effect when BT_FUSE_SEL fuse is `0' (cleared, which is the case for an unblown fuse). For detailed boot mode options configured by the boot mode pins, see the i.MX RT1020 Fuse Map document and the System Boot chapter in i.MX RT1020 Reference Manual (IMXRT1020RM). Table 67.
