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.
3.1.1 Example
This is an example of an operating requirement, which you must meet for the accompanying operating behaviors to be guaranteed:
Symbol VDD Description 1.0 V core supply voltage 0.9 Min. 1.1 Max. V Unit
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, which is guaranteed if you meet the accompanying operating requirements:
Symbol IWP Description Digital I/O weak pullup/ 10 pulldown current Min. 130 Max. µA Unit
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.
K20 Sub-Family Data Sheet Data Sheet, Rev. 6, 9/2011.
Freescale Semiconductor, Inc. 7
Terminology and guidelines
3.3.1 Example
This is an example of an attribute:
Symbol CIN_D Description Input capacitance: digital pins — Min. 7 Max. pF Unit
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 VDD Description 1.0 V core supply voltage –0.3 Min. 1.2 Max. V Unit
3.5 Result of exceeding a rating
40 Failures in time (ppm) 30

The likelihood of permanent chip failure increases rapidly as soon as a characteristic begins to exceed one of its operating ratings.

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 volt tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN greater than VDIO_MIN (=VSS-0.3V) is observed, then there is no need to provide current limiting resistors at the pads. If this limit cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R=(VDIO_MIN-VIN)/|IIC|. 2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. 3. All analog pins are internally clamped to VSS and VDD through ESD protection diodes. If VIN is greater than VAIO_MIN (=VSS-0.3V) and VIN is less than VAIO_MAX(=VDD+0.3V) is observed, then there is no need to provide current limiting resistors at the pads. If these limits cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R=(VAIO_MIN-VIN)/|IIC|. The positive injection current limiting resistor is calcualted as R=(VIN-VAIO_MAX)/|IIC|. Select the larger of these two calculated resistances.

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.

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.

6.6.1 ADC electrical specifications
The 16-bit accuracy specifications listed in Table 27 and Table 28 are achievable on the differential pins ADCx_DP0, ADCx_DM0, ADCx_DP1, ADCx_DM1, ADCx_DP3, and ADCx_DM3. The ADCx_DP2 and ADCx_DM2 ADC inputs are connected to the PGA outputs and are not direct device pins. Accuracy specifications for these pins are defined in Table 29 and Table 30. All other ADC channels meet the 13-bit differential/12-bit single-ended accuracy specifications. 6.6.1.1

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. The analog source resistance should be kept as low as possible in order to achieve the best results. The results in this datasheet were derived from a system which has
