NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other condition above those indicated in the operation section of this specification is not
implied.
2. For operating at elevated temperatures, the device must be derated based on +150
°C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over specified temperature range.

NOTES:
1. Parameters are valid over specified temperature range.
2. Typical values are at +25
°C, typical supply voltages, and typical processing parameters.
3. Test conditions for outputs: CL = 150pF, except interrupt outputs. Test conditions for interrupt outputs: CL = 50pF, RL = 2.7KΩ to VCC.
4. All outputs are disconnected. Inputs are switching between CMOS levels of VCC -0.2V and VSS + 0.2V.
5. See UART application note for power down currents of 5
µA or less.
