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.

3.4 Definition: Rating
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.

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 was obtained at TBD frequency.
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 Freescale developed PCB. PLL jitter is dependent on the noise characteristics of
each PCB and results will vary.
10. This specification was obtained at internal frequency of TBD.
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.

1. Typical data retention values are based on intrinsic capability of the technology measured at high temperature derated to
25°C. For additional information on how Freescale defines typical data retention, please refer to Engineering Bulletin
EB618.
2. Data retention is based on Tjavg = 55°C (temperature profile over the lifetime of the application).
3. Cycling endurance represents number of program/erase cycles at -40°C ≤ Tj ≤ 125°C.
4. 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 (same value as data flash) and the allocated EEPROM backup per subsystem. Minimum value
assumes all byte-writes to FlexRAM.
6.4.1.5
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
FTFL 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.

best results. The results in this datasheet were derived from a system which has <8 Ω analog source resistance. The RAS/
CAS time constant should be kept to <1ns.

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 should be set, the HSC bit should be clear with 1MHz ADC conversion clock
speed.
4. 1 LSB = (VREFH - VREFL)/2N
5. Input data is 1 kHz sine wave.

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 (VREFOUT)
3. PGA reference connected to the VREFOUT pin. If the user wishes to drive VREFOUT with a voltage other than the output
of the VREF module, the VREF module must be disabled.
4. For single ended configurations the input impedence of the driven input is 1/2.
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.

1. Typical values assume VDDA =3.0V, Temp=25°C, fADCK=6MHz unless otherwise stated.
2. Between IN+ and IN-. The PGA draws a DC current from the input terminals. The magnitude of the DC current is a strong
function if input common mode voltage (VCM) and the PGA gain.
3. This is the input leakage current of the module in addition to the PAD leakage current.
4. Gain = 2PGAG
5. When the PGA gain is changed, it takes some time to settle the output for the ADC to work properly. During a gain
switching, a few ADC outputs should be discarded (minimum two data samples, may be more depending on ADC
sampling rate and time of the switching).
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.

6.8.10 I2S switching specifications
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.

The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.
The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.
Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
Measured with a 20 pF electrode, reference oscillator frequency of ~5 MHz (IREF = 5 μA, REFCHRG = 4), PS = 128,
NSCN = 2; Iext = 16 (EXTCHRG = 15).
7. Typical value depends on the configuration used.
