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.

NC

These signals are No Connect (NC) and should be disconnected by the user.

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).

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.

TEST_MODE

WAKEUP

TEST_MODE is for NXP factory use. The user must tie this pin directly to GND.

Development Guide (IMXRT1024HDG).

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.

Electrical characteristics

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.

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.

Electrical characteristics

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 7, 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 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.

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.

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.

Crystal Properties

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.

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).

Signal Configuration as Fuse Override

Input at Power Up.

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.

6.2

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.
