The IDD typical values represent the statistical mean at 25°C, and the IDD maximum
values for RUN, WAIT, VLPR, and VLPW represent data collected at 125°C junction
temperature unless otherwise noted. The maximum values represent characterized
results equivalent to the mean plus three times the standard deviation (mean + 3 sigma).

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.

2. Closed loop operation of the IRC48M is only feasible for USB device operation; it is not usable for USB host operation.

function (USB_CLK_RECOVER_IRC_CTRL[CLOCK_RECOVER_EN]=1,
USB_CLK_RECOVER_IRC_EN[IRC_EN]=1).

All processor bus timings are synchronous; input setup/hold and output delay are
given in respect to the rising edge of a reference clock, FB_CLK. The FB_CLK
frequency may be the same as the internal system bus frequency or an integer divider
of that frequency.
The following timing numbers indicate when data is latched or driven onto the
external bus, relative to the Flexbus output clock (FB_CLK). All other timing

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

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

1. The maximum SCL Clock Frequency in Fast mode with maximum bus loading can only be achieved when using the
High drive pins across the full voltage range and when using the Normal drive pins and VDD ≥ 2.7 V.
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

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

7 Terminology and guidelines
7.1 Definitions
Key terms are defined in the following table:
Term Definition
Rating 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.
Table continues on the next page...
Terminology and guidelines
Kinetis K22F 512KB Flash, Rev. 7.1, 08/2016 77
NXP Semiconductors
Term Definition
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.

7.5 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.
