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 temperature, 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. See Ordering Information table for applicable operating temperature and VCC supply
range.

NOTES:
1. Parameters are valid over specified temperature range. See Ordering Information table for applicable operating temperature and VCC supply
range.
2. All voltage measurements are referenced to ground (GND). For testing, all input signals swing between 0V and 3.0V with a transition time of
20ns max. For X1/CLK, this swing is between 0.4V and 4.0V. All time measurements are referenced at input voltages of 0.8V and 2V and
output voltages of 0.8V and 2V as appropriate.
3. Typical values are at +25°C, typical supply voltages, and typical processing parameters.
4. Test condition for outputs: CL = 150pF, except interrupt outputs. Test conditions for interrupt outputs: CL = 50pF, RL = 2.7kΩ to VCC.
5. For power down current levels in the 1µA region see the UART application note.
