Caution
This device contains circuitry protecting against damage due
to high static voltage or electrical fields. However, normal
precautions should be taken to avoid exceeding maximum
voltage ratings. Reliability of operation is enhanced if unused
inputs are pulled to an appropriate logic voltage level (e.g.,
either GND or VDD). The suggested value for a pullup or
pulldown resistor is 10 kΩ.
NOTE
In the calculation of timing requirements, adding a maximum value of one specification to a
minimum value of another specification does not yield a reasonable sum. A maximum
specification is calculated using a worst case variation of process parameter values in one
direction. The minimum specification is calculated using the worst case for the same
parameters in the opposite direction. Therefore, a “maximum” value for a specification will
never occur in the same device that has a “minimum” value for another specification; adding
a maximum to a minimum represents a condition that can never exist.

Note:
1. GND = 0 V, TJ = 0°C to 95°C (52 LQFP) / 0°C to 90°C (80 LQFP), CL = 50pF
2. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress
beyond the maximum rating may affect device reliability or cause permanent damage to the device.
3. Operating temperature qualified for consumer applications. TJ = TA + θJA x Power.
4. If the power supply ramp to full supply time is longer than 10 ms, the POR circuitry will not operate correctly, causing
erroneous operation.
