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.

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.
3. This is the minimum pulse width that is guaranteed to be recognized as a pin interrupt request in Stop, VLPS, LLS, and
VLLSx modes.

Peripheral operating requirements and behaviors
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.
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.
NOTE
The 32 kHz oscillator works in low power mode by default and
cannot be moved into high power/gain mode.

6.4.3 Flexbus Switching Specifications
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.

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, the ADHSC bit must be set and the ADLPC bit 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 the ADLPC bit (low power).
For lowest power operation the ADLPC bit must be set, the HSC 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)
6. Input data is 100 Hz sine wave. ADC conversion clock < 12 MHz.
7. Input data is 1 kHz sine wave. ADC conversion clock < 12 MHz.

1. Typical values assume VDDA = 3.0 V, Temp = 25°C, fADCK = 6 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
2. ADC must be configured to use the internal voltage reference (VREF_OUT)
3. PGA reference is internally connected to the VREF_OUT pin. If the user wishes to drive VREF_OUT with a voltage other
than the output of the VREF module, the VREF module must be disabled.
4. For single ended configurations the input impedance of the driven input is RPGAD/2
5. The analog source resistance (RAS), external to MCU, should be kept as minimum as possible. Increased RAS causes drop
in PGA gain without affecting other performances. This is not dependent on ADC clock frequency.
6. The minimum sampling time is dependent on input signal frequency and ADC mode of operation. A minimum of 1.25µs
time should be allowed for Fin=4 kHz at 16-bit differential mode. Recommended ADC setting is: ADLSMP=1, ADLSTS=2 at
8 MHz ADC clock.
7. ADC clock = 18 MHz, ADLSMP = 1, ADLST = 00, ADHSC = 1
8. ADC clock = 12 MHz, ADLSMP = 1, ADLST = 01, ADHSC = 1

1. Typical values assume VDDA =3.0V, Temp=25°C, fADCK=6MHz unless otherwise stated.
2. This current is a PGA module adder, in addition to ADC conversion currents.
3. Between IN+ and IN-. The PGA draws a DC current from the input terminals. The magnitude of the DC current is a strong
function of input common mode voltage (VCM) and the PGA gain.
4. Gain = 2PGAG
5. After changing the PGA gain setting, a minimum of 2 ADC+PGA conversions should be ignored.
6. Limit the input signal swing so that the PGA does not saturate during operation. Input signal swing is dependent on the
PGA reference voltage and gain setting.

1. 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.
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 = 10ns and Output Load = 50pf
4. Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty.
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 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.

This section provides the AC timings for the I2S in master (clocks driven) and slave
modes (clocks input). All timings are given for non-inverted serial clock polarity
(TCR[TSCKP] = 0, RCR[RSCKP] = 0) and a non-inverted frame sync (TCR[TFSI] = 0,
RCR[RFSI] = 0). If the polarity of the clock and/or the frame sync have been inverted, all
the timings remain valid by inverting the clock signal (I2S_BCLK) and/or the frame sync
(I2S_FS) shown in the figures below.

1. The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.
2. CAPTRM=7, DELVOL=7, and fixed external capacitance of 20 pF.
3. CAPTRM=0, DELVOL=2, and fixed external capacitance of 20 pF.
4. CAPTRM=0, EXTCHRG=9, and fixed external capacitance of 20 pF.
5. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.
6. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current.
7. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
8. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
10. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes, it is equal to (Cref
* Iext)/( Iref * PS * NSCN). Sensitivity depends on the configuration used. The typical value listed is based on the following
configuration: Iext = 5 μA, EXTCHRG = 4, PS = 128, NSCN = 2, Iref = 16 μA, REFCHRG = 15, Cref = 1.0 pF. The
minimum sensitivity describes the smallest possible capacitance that can be measured by a single count (this is the best
sensitivity but is described as a minimum because it’s the smallest number). The minimum sensitivity parameter is based
on the following configuration: Iext = 1 μA, EXTCHRG = 0, PS = 128, NSCN = 32, Iref = 32 μA, REFCHRG = 31, Cref= 0.5
pF
11. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1
electrode, DELVOL = 2, EXTCHRG = 15.
12. CAPTRM=7, DELVOL=2, REFCHRG=0, EXTCHRG=4, PS=7, NSCN=0F, LPSCNITV=F, LPO is selected (1 kHz), and
fixed external capacitance of 20 pF. Data is captured with an average of 7 periods window.
