Overview
2.1 System features
The following sections describe the high-level system features.
2.1.1 ARM Cortex-M4 core
The ARM Cortex-M4 is the member of the Cortex M Series of processors targeting
microcontroller cores focused on very cost sensitive, deterministic, interrupt driven
environments. The Cortex M4 processor is based on the ARMv7 Architecture and
Thumb®-2 ISA and is upward compatible with the Cortex M3, Cortex M1, and
Cortex M0 architectures. Cortex M4 improvements include an ARMv7 Thumb-2 DSP
(ported from the ARMv7-A/R profile architectures) providing 32-bit instructions with
SIMD (single instruction multiple data) DSP style multiply-accumulates and
saturating arithmetic.
2.1.2 NVIC
The Nested Vectored Interrupt Controller supports nested interrupts and 16 priority
levels for interrupts. In the NVIC, each source in the IPR registers contains 4 bits. It
also differs in number of interrupt sources and supports 240 interrupt vectors.
The Cortex-M family uses a number of methods to improve interrupt latency . It also
can be used to wake the MCU core from Wait and VLPW modes.
2.1.3 AWIC
The asynchronous wake-up interrupt controller (AWIC) is used to detect
asynchronous wake-up events in Stop mode and signal to clock control logic to
resume system clocking. After clock restarts, the NVIC observes the pending interrupt
and performs the normal interrupt or event processing. The AWIC can be used to
wake MCU core from Partial Stop, Stop and VLPS modes.

2.1.6 Clock options
The MCG module controls which clock source is used to derive the system clocks. The
clock generation logic divides the selected clock source into a variety of clock domains,
including the clocks for the system bus masters, system bus slaves, and flash memory .
The clock generation logic also implements module-specific clock gating to allow
granular shutoff of modules.
The primary clocks for the system are generated from the MCGOUTCLK clock. The
clock generation circuitry provides several clock dividers that allow different portions
of the device to be clocked at different frequencies. This allows for trade-offs between
performance and power dissipation.
Various modules, such as the USB OTG Controller, have module-specific clocks that
can be generated from the IRC48MCLK or MCGPLLCLK or MCGFLLCLK clock. In
addition, there are various other module-specific clocks that have other alternate
sources. Clock selection for most modules is controlled by the SOPT registers in the
SIM module.
For more details on the clock operations and configurations, see the Clock Distribution
chapter in the Reference Manual.
The following figure is a high level block diagram of the clock generation.

In order to provide flexibility, many peripherals can select the clock source to use for
operation. This enables the peripheral to select a clock that will always be available
during operation in various operational modes.

Flash Access Control (FAC)
The FAC is a native or third-party configurable memory protection scheme optimized
to allow end users to utilize software libraries while offering programmable
restrictions to these libraries. The flash memory is divided into equal size segments
that provide protection to proprietary software libraries. The protection of these
segments is controlled as the FAC provides a cycle-by-cycle evaluation of the access
rights for each transaction routed to the on-chip flash memory. Configurability allows
an increasing number of protected segments while supporting two levels of vendors
adding their proprietary software to a device.

Overview
2.1.8 Power management
The Power Management Controller (PMC) expands upon ARM’s operational modes of
Run, Sleep, and Deep Sleep, to provide multiple configurable modes. These modes can
be used to optimize current consumption for a wide range of applications. The WFI or
WFE instruction invokes a Wait or a Stop mode, depending on the current
configuration. For more information on ARM’s operational modes, See the ARM®
Cortex® User Guide.
The PMC provides High Speed Run (HSRUN), Normal Run (RUN), and Very Low
Power Run (VLPR) configurations in ARM’s Run operation mode. In these modes, the
MCU core is active and can access all peripherals. The difference between the modes is
the maximum clock frequency of the system and therefore the power consumption. The
configuration that matches the power versus performance requirements of the
application can be selected.
The PMC provides Wait (Wait) and Very Low Power Wait (VLPW) configurations in
ARM’s Sleep operation mode. In these modes, even though the MCU core is inactive,
all of the peripherals can be enabled and operate as programmed. The difference
between the modes is the maximum clock frequency of the system and therefore the
power consumption.
The PMC provides Stop (Stop), Very Low Power Stop (VLPS), Low Leakage Stop
(LLS), and Very Low Leakage Stop (VLLS) configurations in ARM’s Deep Sleep
operational mode. In these modes, the MCU core and most of the peripherals are
disabled. Depending on the requirements of the application, different portions of the
analog, logic, and memory can be retained or disabled to conserve power.
The Battery Backup mode allows the VBAT voltage domain to operate while the rest of
the device is disabled to conserve power. All modules in the VBAT domain are
functional in this mode of operation.
The Nested Vectored Interrupt Controller (NVIC), the Asynchronous Wake-up
Interrupt Controller (AWIC), and the Low Leakage Wake-Up Controller (LLWU) are
used to wake up the MCU from low power states. The NVIC is used to wake up the
MCU core from WAIT and VLPW modes. The AWIC is used to wake up the MCU
core from STOP and VLPS modes. The LLWU is used to wake up the MCU core from
LLS and VLLSx modes.
For additional information regarding operational modes, power management, the NVIC,
AWIC, or the LLWU, please refer to the Reference Manual.

The module supports programmable baud rates independent of bus clock frequency,
with automatic start/stop bit generation.
The FlexIO module has the following features:
• Functional in VLPR/VLPW/Stop/VLPS mode provided the clock it is using
remains enabled
• Four 32-bit double buffered shift registers with transmit, receive, and data match
modes, and continuous data transfer

Overview
• The timing of the shifter's shift, load and store events are controlled by the highly
flexible 16-bit timer assigned to the shifter
• Two or more shifters can be concatenated to support large data transfer sizes
• Each 16-bit timers operates independently, supports for reset, enable and disable on
a variety of internal or external trigger conditions with programmable trigger
polarity
• Flexible pin configuration supporting output disabled, open drain, bidirectional
output data and output mode
• Supports interrupt, DMA or polled transmit/receive operation
2.2.19 Port control and GPIO
The Port Control and Interrupt (PORT) module provides support for port control, digital
filtering, and external interrupt functions. The GPIO data direction and output data
registers control the direction and output data of each pin when the pin is configured for
the GPIO function. The GPIO input data register displays the logic value on each pin
when the pin is configured for any digital function, provided the corresponding Port
Control and Interrupt module for that pin is enabled.
The following figure shows the basic I/O pad structure. This diagram applies to all I/O
pins except RESET_b and those configured as pseudo open-drain outputs. RESET_b is
a true open-drain pin without p-channel output driver or diode to the ESD bus. Pseudo
open-drain pins have the p-channel output driver disabled when configured for opendrain operation. None of the I/O pins, including open-drain and pseudo open-drain pins,
are allowed to go above VDD.

Electrical characteristics
5.1.1 Definitions
Key terms are defined in the following table:
Term
Rating
Definition
A minimum or maximum value of a technical characteristic that, if exceeded, may cause
permanent chip failure:
• Operating ratings apply during operation of the chip.
• Handling ratings apply when the chip is not powered.
NOTE: The likelihood of permanent chip failure increases rapidly as soon as a characteristic
begins to exceed one of its operating ratings.
Operating requirement A specified value or range of values for a technical characteristic that you must guarantee during
operation to avoid incorrect operation and possibly decreasing the useful life of the chip
Operating behavior
A specified value or range of values for a technical characteristic that are guaranteed during
operation if you meet the operating requirements and any other specified conditions
Typical value
A specified value for a technical characteristic that:
• Lies within the range of values specified by the operating behavior
• Is representative of that characteristic during operation when you meet the typical-value
conditions or other specified conditions
NOTE: Typical values are provided as design guidelines and are neither tested nor
guaranteed.

5.1.5 Guidelines for ratings and operating requirements
Follow these guidelines for ratings and operating requirements:
• Never exceed any of the chip’s ratings.
• During normal operation, don’t exceed any of the chip’s operating requirements.
• If you must exceed an operating requirement at times other than during normal
operation (for example, during power sequencing), limit the duration as much as
possible.

1. USB nominal operating voltage is 3.3 V.
2. All analog and I/O pins are internally clamped to VSS through ESD protection diodes. If VIN is less than VIO_MIN or greater
than VIO_MAX, a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as
R=(VIO_MIN-VIN)/|IICIO|.
3. Open drain outputs must be pulled to VDD.

5.3.2.6 EMC performance
Electromagnetic compatibility (EMC) performance is highly dependent on the
environment in which the MCU resides. Board design and layout, circuit topology
choices, location and characteristics of external components, and MCU software
operation play a significant role in the EMC performance. The system designer can
consult the following Freescale applications notes, available on freescale.com for
advice and guidance specifically targeted at optimizing EMC performance.

1. This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may
or may not be recognized. In Stop, VLPS, LLS, and VLLSx modes, the synchronizer is bypassed so shorter pulses can
be recognized in that case.
2. The greater of synchronous and asynchronous timing must be met.
3. These pins have a passive filter enabled on the inputs. This is the shortest pulse width that is guaranteed to be
recognized.
4. These pins do not have a passive filter on the inputs. This is the shortest pulse width that is guaranteed to be

1. This parameter is measured with the internal reference (slow clock) being used as a reference to the FLL (FEI clock
mode).
2. 2.0 V <= VDD <= 3.6 V.
3. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=0.
4. The resulting system clock frequencies should not exceed their maximum specified values. The DCO frequency
deviation (Δfdco_t) over voltage and temperature should be considered.
5. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=1.
6. The resulting clock frequency must not exceed the maximum specified clock frequency of the device.
7. This specification applies to any time the FLL reference source or reference divider is changed, trim value is changed,
DMX32 bit is changed, DRS bits are changed, or changing from FLL disabled (BLPE, BLPI) to FLL enabled (FEI, FEE,
FBE, FBI). If a crystal/resonator is being used as the reference, this specification assumes it is already running.
8. Excludes any oscillator currents that are also consuming power while PLL is in operation.
9. This specification was obtained using a NXP developed PCB. PLL jitter is dependent on the noise characteristics of
each PCB and results will vary.
10. This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL
disabled (BLPE, BLPI) to PLL enabled (PBE, PEE). If a crystal/resonator is being used as the reference, this
specification assumes it is already running.

1. The maximum value represents characterized results equivalent to the mean plus or minus three times the standard
deviation (mean ± 3 sigma).
2. Closed loop operation of the IRC48M is only feasible for USB device operation; it is not usable for USB host operation.
It is enabled by configuring for USB Device, selecting IRC48M as USB clock source, and enabling the clock recover
function (USB_CLK_RECOVER_IRC_CTRL[CLOCK_RECOVER_EN]=1,
USB_CLK_RECOVER_IRC_EN[IRC_EN]=1).
3. IRC48M startup time is defined as the time between clock enablement and clock availability for system use. Enable
the clock by one of the following settings:
• USB_CLK_RECOVER_IRC_EN[IRC_EN]=1 or
• MCG operating in an external clocking mode and MCG_C7[OSCSEL]=10 or MCG_C5[PLLCLKEN0]=1, or

1. Other frequency limits may apply when external clock is being used as a reference for the FLL or PLL.
2. When transitioning from FEI or FBI to FBE mode, restrict the frequency of the input clock so that, when it is divided by
FRDIV, it remains within the limits of the DCO input clock frequency.
3. Proper PC board layout procedures must be followed to achieve specifications.
4. Crystal startup time is defined as the time between the oscillator being enabled and the OSCINIT bit in the MCG_S
register being set.

1. Typical values assume VDDA = 3.0 V, Temp = 25 °C, fADCK = 1.0 MHz, unless otherwise stated. Typical values are for
reference only, and are not tested in production.
2. DC potential difference.
3. This resistance is external to MCU. To achieve the best results, the analog source resistance must be kept as low as
possible. The results in this data sheet were derived from a system that had < 8 Ω analog source resistance. The
RAS/CAS time constant should be kept to < 1 ns.
4. To use the maximum ADC conversion clock frequency, CFG2[ADHSC] must be set and CFG1[ADLPC] must be clear.
5. For guidelines and examples of conversion rate calculation, download the ADC calculator tool.

I2S/SAI switching specifications
This section provides the AC timing for the I2S/SAI module in master mode (clocks are
driven) and slave mode (clocks are input). All timing is given for noninverted serial
clock polarity (TCR2[BCP] is 0, RCR2[BCP] is 0) and a noninverted frame sync
(TCR4[FSP] is 0, RCR4[FSP] is 0). If the polarity of the clock and/or the frame sync
have been inverted, all the timing remains valid by inverting the bit clock signal
(BCLK) and/or the frame sync (FS) signal shown in the following figures.

6 Design considerations
6.1 Hardware design considerations
This device contains protective circuitry to guard against damage due to high static
voltage or electric fields. However, take normal precautions to avoid application of any
voltages higher than maximum-rated voltages to this high-impedance circuit.
6.1.1 Printed circuit board recommendations
• Place connectors or cables on one edge of the board and do not place digital circuits
between connectors.
• Drivers and filters for I/O functions must be placed as close to the connectors as
possible. Connect TVS devices at the connector to a good ground. Connect filter
capacitors at the connector to a good ground.
• Physically isolate analog circuits from digital circuits if possible.
• Place input filter capacitors as close to the MCU as possible.
• For best EMC performance, route signals as transmission lines; use a ground plane
directly under LQFP packages; and solder the exposed pad (EP) to ground directly
under QFN packages.

Design considerations
6.1.2 Power delivery system
Consider the following items in the power delivery system:
• Use a plane for ground.
• Use a plane for MCU VDD supply if possible.
• Always route ground first, as a plane or continuous surface, and never as
sequential segments.
• Route power next, as a plane or traces that are parallel to ground traces.
• Place bulk capacitance, 10 μF or more, at the entrance of the power plane.
• Place bypass
 capacitors for MCU power domain as close as possible to each
VDD/VSS pair, including VDDA/VSSA and VREFH/VREFL.
• The minimum bypass requirement is to place 0.1 μF capacitors positioned as near
as possible to the package supply pins.

• The USB_VDD
voltage range is 3.0 V to 3.6 V. It is recommended to include a
filter circuit with one bulk capacitor (no less than 2.2 μF) and one 0.1 μF capacitor

at the USB_VDD
pin to improve USB performance.

6.1.3 Analog design
Each ADC input must have an RC filter as shown in the following figure. The
maximum value
of R must be RAS max if fast sampling and high resolution are


required. The value
of C must be chosen to ensure that the RC time constant is very
small compared to the sample period.


High voltage measurement
circuits require voltage division, current limiting, and
over-voltage protection as shown the following figure. The voltage divider formed by
R1 – R4 must yield
a voltage less than or equal to VREFH. The current must be

limited to less than the injection current limit. Since the ADC pins do not have diodes
to VDD, external clamp diodes must be included to protect against transient overvoltages.

must be used to avoid damaging the supervisor chip or the RESET_b pin,
as shown in the following figure. The series resistor value (RS below) must be in
the range of 100 Ω to 1 kΩ depending on the external reset chip drive strength.
The supervisor chip must have an active high, open-drain output.

Unused GPIO pins must be left floating (no electrical connections) with the MUX
field of the pin’s PORTx_PCRn register equal to 0:0:0. This disables the digital
input path to the MCU.

If the USB module is not used, leave the USB data pins (USB0_DP, USB0_DM)
floating. Connect USB_VDD to ground through a 10 kΩ resistor if the USB module
is not used.
6.1.5 Crystal oscillator
When using an external crystal or ceramic resonator as the frequency reference for the
MCU clock system, refer to the following table and diagrams.
The feedback resistor, RF, is incorporated internally with the low power oscillators. An
external feedback is required when using high gain (HGO=1) mode.

Design considerations
Internal load capacitors (Cx, Cy) are provided in the low frequency (32.786 kHz)
mode. Use the SCxP bits in the OSC0_CR register to adjust the load capacitance for
the crystal. Typically, values of 10pf to 16 pF are sufficient for 32.768 kHz crystals
that have a 12.5 pF CL specification. The internal load capacitor selection must not be
used for high frequency crystals and resonators.
