• 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 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

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. 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.
6. Excludes any oscillator currents that are also consuming power while PLL is in operation.

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.
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
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.

The SCALER value is derived from the fractional divider specified in the SIM's
CLKDIV4 register:
SCALER =SIM_CLKDIV4[NFCFRAC] + 1
SIM_CLKDIV4[NFCDIV] + 1
In case the reciprocal of SCALER is an integer, the duty cycle of NFC clock is 50%,
means TH = TL. In case the reciprocal of SCALER is not an integer:

1. All accuracy numbers assume the ADC is calibrated with VREFH = VDDA
2. The ADC supply current depends on the ADC conversion clock speed, conversion rate and ADC_CFG1[ADLPC] (low
power). For lowest power operation, ADC_CFG1[ADLPC] must be set, the ADC_CFG2[ADHSC] bit must be clear with 1
MHz ADC conversion clock speed.
3. 1 LSB = (VREFH - VREFL)/2N
4. ADC conversion clock < 16 MHz, Max hardware averaging (AVGE = %1, AVGS = %11)
5. Input data is 1 kHz sine wave. ADC conversion clock < 12 MHz.
6. ADC conversion clock < 3 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. 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.

6.8.11 I2S/SAI switching specifications
This section provides the AC timing for the I2S/SAI module in master mode (clocks are
driven) and slave mode (clocks are input). All timing is given for noninverted serial clock
polarity (TCR2[BCP] is 0, RCR2[BCP] is 0) and a noninverted frame sync (TCR4[FSP]
is 0, RCR4[FSP] is 0). If the polarity of the clock and/or the frame sync have been
inverted, all the timing remains valid by inverting the bit clock signal (BCLK) and/or the
frame sync (FS) signal shown in the following figures.

1. The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.
2. Fixed external capacitance of 20 pF.
3. REFCHRG = 2, EXTCHRG=0.
4. REFCHRG = 0, EXTCHRG = 10.
5. VDD = 3.0 V.
6. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
7. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
8. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
9. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes. Sensitivity
depends on the configuration used. The documented values are provided as examples calculated for a specific
configuration of operating conditions using the following equation: (Cref * Iext)/( Iref * PS * NSCN)
The typical value is calculated with the following configuration:
Iext = 6 μA (EXTCHRG = 2), PS = 128, NSCN = 2, Iref = 16 μA (REFCHRG = 7), Cref = 1.0 pF
The minimum value is calculated with the following configuration:
Iext = 2 μA (EXTCHRG = 0), PS = 128, NSCN = 32, Iref = 32 μA (REFCHRG = 15), Cref = 0.5 pF
The highest possible sensitivity is the minimum value because it represents the smallest possible capacitance that can be
measured by a single count.
10. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1
electrode, EXTCHRG = 7.
11. 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.

Table 57. Revision History (continued)
Rev. No. Date Substantial Changes
4 10/2012 Replaced TBDs throughout.
5 10/2013 Changes for 4N96B mask set:
• Min VDD operating requirement specification updated to support operation down to
1.71V.
New specifications:
• Added Vodpu specification.
• Removed Ioz, Ioz_ddr, and Ioz_tamper Hi-Z leakage specficiations. They have been
replaced by new Iina, Iind, and Zind specifications.
• Fpll_ref_acc specification has been added.
• I2C module was previously covered by the general switching specifications. To provide
more detail on I2C operation a dedicated Inter-Integrated Circuit Interface (I2C) timing
section has been added.
Modified specifications:
• Vref_ddr max spec has been updated.
• Tpor spec has been split into two specifications based on VDD slew rate.
• Trd1allx and Trd1alln max have been updated.
• 16-bit ADC Temp sensor slope and Temp sensor voltage (Vtemp25) have been
modified. The typical values that were listed previously have been updated, and min
and max specifications have been added.
Corrections:
• Some versions of the datasheets listed incorrect clock mode information in the
"Diagram: Typical IDD_RUN operating behavior section." These errors have been
corrected.
• Fintf_ft specification was previously shown as a max value. It has been corrected to be
shown as a typical value as originally intended.
• Corrected DDR write and read timing diagrams to show the correct location of the Tcmv
specification.
• SDHC peripheral 50MHz high speed mode options were left out of the last datasheet.
These have been added to the SDHC specifications section.
