Special signal considerations
Table 5 lists special signal considerations for the i.MX RT1024 processors. The signal names are listed in
alphabetical order.
The package contact assignments can be found in Section 7, Package information and contact
assignments.” Signal descriptions are provided in the i.MX RT1024 Reference Manual
(IMXRT1024RM).
Table 5. 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 6. 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 RT1024 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.

POR_B
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.

4.1.4
External clock sources
Each i.MX RT1024 processor has two external input system clocks: a low frequency (RTC_XTALI) and
a high frequency (XTALI).
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.

4.2.1
Power supplies requirements and restrictions
The system design must comply with power-up sequence, power-down sequence, and steady state
guidelines as described in this section to guarantee the reliable operation of the device. 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 RT1024 Reference Manual
(IMXRT1024RM) 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 and VDDA_ADC_3P3 are not part of the power
supply sequence and may be powered at any time.

named *_CAP must be connected to external capacitors. The onboard LDOs are intended for internal use
only and should not be used to power any external circuitry. See the i.MX RT1024 Reference Manual
(IMXRT1024RM) 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 RT1024 Reference Manual (IMXRT1024RM).
4.2.2.2
Regulators for analog modules
LDO_1P1
4.2.2.2.1
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 additional information, see the i.MX RT1024 Reference Manual (IMXRT1024RM).
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 RT1024 Crossover Processors (IMXRT1024HDG).
For additional information, see the i.MX RT1024 Reference Manual (IMXRT1024RM).
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 RT1024 Crossover Processors (IMXRT1024HDG).
For additional information, see the i.MX RT1024 Reference Manual (IMXRT1024RM).
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.

Electrical characteristics
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 RT1024 Reference Manual (IMXRT1024RM).

On-chip oscillators
OSC24M
4.2.4.1
This block implements an amplifier that when combined with a suitable quartz crystal and external load
capacitors implement an oscillator. 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:
•
•
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.

This frequency is nominal and determined mainly by the crystal selected.

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.

Overshoot and undershoot conditions (transitions above NVCC_XXXX and below GND) on switching pads must be held
below 0.6 V, and the duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. 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.

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.
Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.

FlexSPI parameters1
Measurements are with a load 15 pf and input slew rate of 1 V/ns.
4.5.2.1 FlexSPI input/read timing
There are four sources for the internal sample clock for FlexSPI read data:
• Dummy read strobe generated by FlexSPI controller and looped back internally
(FlexSPIn_MCR0[RXCLKSRC] = 0x0)
• Dummy read strobe generated by FlexSPI controller and looped back through the
DQS pad (FlexSPIn_MCR0[RXCLKSRC] = 0x1)
• Read strobe provided by memory device and input from DQS pad
(FlexSPIn_MCR0[RXCLKSRC] = 0x3)
The following sections describe input signal timing for each of these four internal sample clock sources.

This section provide information about SAI/I2S and SPDIF.
4.6.1
SAI/I2S switching specifications
This section provides the AC timings for the SAI in master (clocks driven) and slave (clocks input) modes.
All timings are given for non-inverted serial clock polarity (SAI_TCR[TSCKP] = 0, SAI_RCR[RSCKP]
= 0) and non-inverted frame sync (SAI_TCR[TFSI] = 0, SAI_RCR[RFSI] = 0). 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.

SPDIF timing parameters
The Sony/Philips Digital Interconnect Format (SPDIF) data is sent using the bi-phase marking code. When
encoding, the SPDIF data signal is modulated by a clock that is twice the bit rate of the data signal.
Table 48 and Figure 30 and Figure 31 show SPDIF timing parameters for the Sony/Philips Digital
Interconnect Format (SPDIF), including the timing of the modulating Rx clock (SPDIF_SR_CLK) for
SPDIF in Rx mode and the timing of the modulating Tx clock (SPDIF_ST_CLK) for SPDIF in Tx mode.

Boot mode configuration
6 Boot mode configuration
This section provides information on boot mode configuration pins allocation and boot devices interfaces
allocation.
6.1
Boot mode configuration pins
Table 68 provides boot options, functionality, fuse values, and associated pins. 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 RT1024
Fuse Map document and the System Boot chapter in i.MX RT1024 Reference Manual (IMXRT1024RM).

These are special I/O lines that control
the boot up configuration during
product development. In production,
the boot configuration can be
controlled by fuses.

Boot device interface allocation
The following tables list the interfaces that can be used by the boot process in accordance with the specific
boot mode configuration. The tables also describe the interface’s specific modes and IOMUXC allocation,
which are configured during boot when appropriate.
