  1. Stresses beyond those listed as absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Section 5.4, Recommended Operating Conditions, is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
  2. All voltage values are with respect to VSS, unless otherwise noted.
  3. See I/Os supplied by this power pin in Table 4-1Pin Attributes
  4. VDD is the voltage on the corresponding power-supply pin(s) for the IO.
  5. Per JEDEC JESD78 at 125°C with specified I/O pin injection current and clamp voltage of 1.5 times maximum recommended I/O voltage and negative 0.5 times maximum recommended I/O voltage.
  6. Per JEDEC JESD78 at 125°C.
  7. The maximum valid input voltage on an IO pin cannot exceed 0.3 volts when the supply powering the IO is turned off. This requirement applies to all the IO pins which are not fail-safe and for all values of IO supply voltage. Special attention should be applied anytime peripheral devices are not powered from the same power sources used to power the respective IO supply. It is important the attached peripheral never sources a voltage outside the valid input voltage range, including power supply ramp-up and ramp-down sequences.
