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

conditions
Typical values are provided as design guidelines and are neither tested nor guaranteed.

VRAM
VDD voltage required to retain RAM
1. The device always interprets an input as a 1 when the input is greater than or equal to VIH (min.) and less than or equal to
VIH (max.), regardless of whether input hysteresis is turned on.
2. The device always interprets an input as a 0 when the input is less than or equal to VIL (max.) and greater than or equal to
VIL (min.), regardless of whether input hysteresis is turned on.
3. All functional non-supply pins are internally clamped to VSS and VDD. Input must be current limited to the value specified.
To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp
voltages, then use the larger of the two values. Power supply must maintain regulation within operating VDD range during
instantaneous and operating maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the
injection current may flow out of VDD and could result in external power supply going out of regulation. Ensure external
VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not
consuming power. Examples are: if no system clock is present, or if clock rate is very low (which would reduce overall
power consumption).

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 FEI or FBI to FBE 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.

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. Minimum and typical

6.4.3 Mini-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 Mini-Flexbus output clock (FB_CLK). All other timing relationships

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, CFG2[ADHSC] must be set and CFG1[ADLPC] must be clear.
