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. PTB0, PTB1, PTD6, and PTD7 I/O have both high drive and normal drive capability selected by the associated
PTx_PCRn[DSE] control bit. All other GPIOs are normal drive only.
2. The reset pin only contains an active pull down device when configured as the RESET signal or as a GPIO. When
configured as a GPIO output, it acts as a pseudo open drain output.
3. Measured at VDD = 3.6 V
4. Measured at VDD supply voltage = VDD min and Vinput = VSS
2.2.4 Power mode transition operating behaviors
All specifications except tPOR and VLLSx→RUN recovery times in the following table
assume this clock configuration:
• CPU and system clocks = 48 MHz
• Bus and flash clock = 24 MHz
• FEI clock mode
POR and VLLSx→RUN recovery use FEI clock mode at the default CPU and system
frequency of 21 MHz, and a bus and flash clock frequency of 10.5 MHz.

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.

Peripheral operating requirements and behaviors
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 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.
3.5 Security and integrity modules
There are no specifications necessary for the device's security and integrity modules.
3.6 Analog
3.6.1 ADC electrical specifications
The 16-bit accuracy specifications listed in Table 25 and Table 26 are achievable on the
differential pins ADC0_DPx, ADC0_DMx.
All other ADC channels meet the 13-bit differential/12-bit single-ended accuracy
specifications.

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. VREFH is internally tied to VDDA.
4. VREFL is internally tied to VSSA.
5. 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.
6. To use the maximum ADC conversion clock frequency, CFG2[ADHSC] must be set and CFG1[ADLPC] must be clear.
