1. All I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN
greater than VIO_MIN (= VSS-0.3 V) is observed, then there is no need to provide current limiting resistors at the pads. If
this limit cannot be observed then a current limiting resistor is required. The negative DC injection current limiting
resistor is calculated as R = (VIO_MIN - VIN)/|IICIO|.
2. Open drain outputs must be pulled to VDD.

1. This parameter is measured with the internal reference (slow clock) being used as a reference to the FLL (FEI clock
mode).
2. The deviation is relative to the factory trimmed frequency at nominal VDD and 25 °C, fints_ft.
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 must not exceed their maximum specified values. The DCO frequency deviation
(Δfdco_t) over voltage and temperature must 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 is based on standard deviation (RMS) of period or frequency.
8. 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.
9. Excludes any oscillator currents that are also consuming power while PLL is in operation.
10. This specification was obtained using a Freescale developed PCB. PLL jitter is dependent on the noise characteristics
of each PCB and results will vary.
11. 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. 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.

1. All accuracy numbers assume the ADC is calibrated with VREFH = VDDA
2. Typical values assume VDDA = 3.0 V, Temp = 25 °C, fADCK = 2.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
3. The ADC supply current depends on the ADC conversion clock speed, conversion rate and ADC_CFG1[ADLPC] (low
power). For lowest power operation, ADC_CFG1[ADLPC] must be set, the ADC_CFG2[ADHSC] bit must be clear with 1
MHz ADC conversion clock speed.
4. 1 LSB = (VREFH - VREFL)/2N
5. ADC conversion clock < 16 MHz, Max hardware averaging (AVGE = %1, AVGS = %11)

3.8.3 SPI switching specifications
The Serial Peripheral Interface (SPI) provides a synchronous serial bus with master and
slave operations. Many of the transfer attributes are programmable. The following
tables provide timing characteristics for classic SPI timing modes. See the SPI chapter
of the chip's Reference Manual for information about the modified transfer formats used
for communicating with slower peripheral devices.
All timing is shown with respect to 20% VDD and 80% VDD thresholds, unless noted, as
well as input signal transitions of 3 ns and a 30 pF maximum load on all SPI pins.

2. The master mode I2C deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves
acknowledge this address byte, then a negative hold time can result, depending on the edge rates of the SDA and
SCL lines.
3. The maximum tHD; DAT must be met only if the device does not stretch the LOW period (tLOW) of the SCL signal.
4. Input signal Slew = 10 ns and Output Load = 50 pF
5. Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty.
6. A Fast mode I2C bus device can be used in a Standard mode I2C bus system, but the requirement tSU; DAT ≥ 250 ns
must then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If
such a device does stretch the LOW period of the SCL signal, then it must output the next data bit to the SDA line trmax
+ tSU; DAT = 1000 + 250 = 1250 ns (according to the Standard mode I2C bus specification) before the SCL line is
released.
7. Cb = total capacitance of the one bus line in pF.

3.8.6 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.

8Terminology and guidelines
8.1 Definition: Operating requirement
An operating requirement is 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.
8.1.1 Example
This is an example of an operating requirement:
Symbol Description Min. Max. Unit
VDD 1.0 V core supply
voltage
0.9 1.1 V
8.2 Definition: Operating behavior
Unless otherwise specified, an operating behavior is 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.
Terminology and guidelines
60 Kinetis KL46 Sub-Family, Rev5 08/2014.
Freescale Semiconductor, Inc.
8.3 Definition: Attribute
An attribute is a specified value or range of values for a technical characteristic that
are guaranteed, regardless of whether you meet the operating requirements.
8.3.1 Example
This is an example of an attribute:
Symbol Description Min. Max. Unit
CIN_D Input capacitance:
digital pins
7 pF
8.4 Definition: Rating
A rating is 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.
8.4.1 Example
This is an example of an operating rating:
Symbol Description Min. Max. Unit
VDD 1.0 V core supply
voltage
–0.3 1.2 V
Terminology and guidelines

Failures in time (ppm)
The likelihood of permanent chip failure increases rapidly as
soon as a characteristic begins to exceed one of its operating ratings.

8.7 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.
Terminology and guidelines
62 Kinetis KL46 Sub-Family, Rev5 08/2014.
Freescale Semiconductor, Inc.
8.8 Definition: Typical value
A typical value is a specified value for a technical characteristic that:
Lies within the range of values specified by the operating behavior
Given the typical manufacturing process, is representative of that characteristic
during operation when you meet the typical-value conditions or other specified
conditions
Typical values are provided as design guidelines and are neither tested nor guaranteed.
8.8.1 Example 1
This is an example of an operating behavior that includes a typical value:
Symbol Description Min. Typ. Max. Unit
IWP Digital I/O weak
