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. Terminology and guidelines K20 Sub-Family Data Sheet, Rev. 3, 6/2013. Freescale Semiconductor, Inc. 5
3.1.1 Example
This is an example of an operating requirement: Symbol Description Min. Max. Unit VDD 1.0 V core supply voltage 0.9 1.1 V
3.2 Definition: Operating behavior
An operating behavior is a specified value or range of values for a technical characteristic that are guaranteed during operation if you meet the operating requirements and any other specified conditions.
3.2.1 Example
This is an example of an operating behavior: Symbol Description Min. Max. Unit IWP Digital I/O weak pullup/ pulldown current 10 130 µA
3.3 Definition: Attribute
An attribute is a specified value or range of values for a technical characteristic that are guaranteed, regardless of whether you meet the operating requirements.
3.3.1 Example
This is an example of an attribute: Symbol Description Min. Max. Unit CIN_D Input capacitance: digital pins — 7 pF Terminology and guidelines K20 Sub-Family Data Sheet, Rev. 3, 6/2013. 6 Freescale Semiconductor, Inc.
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.
3.4.1 Example
This is an example of an operating rating: Symbol Description Min. Max. Unit VDD 1.0 V core supply voltage –0.3 1.2 V
3.5 Result of exceeding a rating
Failures in time (ppm) The likelihood of permanent chip failure increases rapidly as soon as a characteristic begins to exceed one of its operating ratings. Terminology and guidelines K20 Sub-Family Data Sheet, Rev. 3, 6/2013. Freescale Semiconductor, Inc. 7
3.6 Relationship between ratings and operating requirements
- No permanent failure - Correct operation Normal operating rangeFatal range Expected permanent failure Fatal range Expected permanent failure Operating rating (max.)Operating requirement (max.)Operating requirement (min.)Operating rating (min.) Operating (power on) Degraded operating range Degraded operating range No permanent failure Handling rangeFatal range Expected permanent failure Fatal range Expected permanent failure Handling rating (max.)Handling rating (min.) Handling (power off) - No permanent failure - Possible decreased life - Possible incorrect operation - No permanent failure - Possible decreased life - Possible incorrect operation
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.

- ADC must be configured to use the internal voltage reference (VREF_OUT)

than the output of the VREF module, the VREF module must be disabled.
- For single ended configurations the input impedance of the driven input is R PGAD/2
- The analog source resistance (R AS), 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.

- The master mode I 2C deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves
- The maximum tHD; DAT must be met only if the device does not stretch the LOW period (tLOW) of the SCL signal.
- Input signal Slew = 10 ns and Output Load = 50 pF
- Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty.
- A Fast mode I 2C bus device can be used in a Standard mode I2C bus system, but the requirement tSU; DAT ≥ 250 ns must
= 1000 + 250 = 1250 ns (according to the Standard mode I2C bus specification) before the SCL line is released.
- C b = total capacitance of the one bus line in pF.

- 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. V DD = 3.0 V. 6. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current. 7. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current. 8. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16. 9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16. 10. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16. 11. 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. 12. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1 electrode, EXTCHRG = 7. 13. 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.
