1. Digital pins have a general purpose I/O port assigned (e.g. PTA0). Analog pins do not have an associated general
purpose I/O port.
2. All digital and analog I/O pins are internally clamped to VSS through an ESD protection diode. There is no diode
connection to VDD. If VIN is less than VSS-0.3V, a current limiting resistor is required. The minimum negative DC
injection current limiting resistor value is calculated as R=(-0.3-VIN)/|IICDIO| or R=(-0.3-VIN)/|IICAIO|. The actual resistor
should be an order of magnitude higher to tolerate transient voltages.
3. Open drain outputs must be pulled to VDD.

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 synchronous and asynchronous timing must be met.
3. This is the minimum pulse width that is guaranteed to be recognized as a pin interrupt request in Stop, VLPS, LLS,

1. This parameter is measured with the internal reference (slow clock) being used as a reference to the FLL (FEI clock
mode).
2. This applies when SCTRIM at value (0x80) and SCFTRIM control bit at value (0x0).
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.

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).

1. Typical data retention values are based on measured response accelerated at high temperature and derated to a
constant 25°C use profile. Engineering Bulletin EB618 does not apply to this technology. Typical endurance defined in
Engineering Bulletin EB619.
2. Cycling endurance represents number of program/erase cycles at -40°C ≤ Tj ≤ 125°C.
3. Write endurance represents the number of writes to each FlexRAM location at -40°C ≤Tj ≤ 125°C influenced by the
cycling endurance of the FlexNVM and the allocated EEPROM backup per subsystem. Minimum and typical values
assume all 16-bit or 32-bit writes to FlexRAM; all 8-bit writes result in 50% less endurance.

3.4.1.5 Write endurance to FlexRAM for EEPROM
When the FlexNVM partition code is not set to full data flash, the EEPROM data set
size can be set to any of several non-zero values.
The bytes not assigned to data flash via the FlexNVM partition code are used by the
FTFE to obtain an effective endurance increase for the EEPROM data. The built-in
EEPROM record management system raises the number of program/erase cycles that
can be attained prior to device wear-out by cycling the EEPROM data through a larger
EEPROM NVM storage space.
While different partitions of the FlexNVM are available, the intention is that a single
choice for the FlexNVM partition code and EEPROM data set size is used throughout
the entire lifetime of a given application. The EEPROM endurance equation and graph
shown below assume that only one configuration is ever used.

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
relationships can be derived from these values.

possible. The results in this data sheet were derived from a system that had < 8 Ω analog source resistance. The

2. Operation range is 2.7 V to 5.5 V; tolerance voltage is up to 6 V.
3. 150mA is inclusive of the run mode current of the on-chip USB modules. Available load outside of the chip depends on
USB operation and device power dissipation limits.
4. The target voltage for the regulator is programmable, accounting for the range of the max and min values
5. Current limit disabled.
6. Current limit should be disabled after the powers have stabilized to allow full functionality of the regulator.
7. Limited Characterization
8. IINRUSH with VREGINx=4.0 V to 5.5 V
9. The minimum value of IINRUSH is stated for operation when only one of VREG_IN0 / VREG_IN1 is powered, or when
VREG_IN0 and VREG_IN1 both have the same voltage level. When VREG_IN0 and VREG_IN1 are operated at
different voltage levels with the selected VREG_IN lower than the non-selected VREG_IN, the minumum value of
IINRUSH may decrease to a lower value.
10. Total current load on startup should be less than IINRUSH min over full input voltage range of the regulator.

acknowledge this address byte, then a negative hold time can result, depending on the edge rates of the SDA and SCL
lines.
2. The maximum tHD; DAT must be met only if the device does not stretch the LOW period (tLOW) of the SCL signal.
3. Input signal Slew = 10 ns and Output Load = 50 pF

5. 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

8Terminology and guidelines
8.1 Definitions
Key terms are defined in the following table:
Terminology and guidelines
86 Kinetis K66 Sub-Family, Rev. 4, 04/2017
NXP Semiconductors
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.
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.

8.5 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.
