3 Terminology and guidelines
3.1 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.

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.

3.7 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.
3.8 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.

Unless otherwise specified, propagation delays are measured from the 50% to the 50%
point, and rise and fall times are measured at the 20% and 80% points, as shown in the
following figure.

All digital I/O switching characteristics assume:
1. output pins
• have CL=30pF loads,
• are configured for fast slew rate (PORTx_PCRn[SRE]=0), and
• are configured for high drive strength (PORTx_PCRn[DSE]=1)
2. input pins

1. All 5 V tolerant digital 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 VDIO_MIN, a current limiting resistor is required. The negative DC injection current
limiting resistor is calculated as R=(VDIO_MIN-VIN)/|IICDIO|.
2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. Additionally, EXTAL and
XTAL are analog pins.
3. All analog pins are internally clamped to VSS and VDD through ESD protection diodes. If VIN is less than VAIO_MIN or greater
than VAIO_MAX, a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as
R=(VAIO_MIN-VIN)/|IICAIO|. The positive injection current limiting resistor is calculated as R=(VIN-VAIO_MAX)/|IICAIO|. Select the
larger of these two calculated resistances if the pin is exposed to positive and negative injection currents.
4. Open drain outputs must be pulled to VDD.

Typical values characterized at 25°C and VDD = 3.6 V unless otherwise noted.
Open drain outputs must be pulled to VDD.
Analog pins are defined as pins that do not have an associated general purpose I/O port function.
Digital pins have an associated GPIO port function and have 5V tolerant inputs, except EXTAL and XTAL.
Internal pull-up/pull-down resistors disabled.
Characterized, not tested in production.
Examples calculated using VIL relation, VDD, and max IIND: ZIND=VIL/IIND. This is the impedance needed to pull a high
signal to a level below VIL due to leakage when VIL < VIN < VDD. These examples assume signal source low = 0 V.

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.

1. This parameter is measured with the internal reference (slow clock) being used as a reference to the FLL (FEI clock
mode).
2. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=0.
3. 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.
4. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=1.
5. The resulting clock frequency must not exceed the maximum specified clock frequency of the device.
6. 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.
7. Excludes any oscillator currents that are also consuming power while PLL is in operation.
8. This specification was obtained using a Freescale developed PCB. PLL jitter is dependent on the noise characteristics of
each PCB and results will vary.
9. 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. Other frequency limits may apply when external clock is being used as a reference for the FLL or PLL.
2. When transitioning from FBE to FEI 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.

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.

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.
