Description
The DE function is not available on Port A2 as specified.
Workaround
None.
The VBO will generate a reset at higher supply voltage levels than specified.
Workaround
Ensure that the supply voltage does not drop below 2.8 V.
LVD levels are about 200 mV higher than specified.
Workaround
For lower precision applications, set the detect level 200 mV lower than
specified.
Description
The IPO frequency is specified to be 5.5296 MHz +/- 4% over the supply
voltage range of 2.7 V to 3.6 V and the temperature range of -40 °C to +105
°C. Actual silicon performance is +/-4% only over a supply voltage range of
3.15 V to 3.45 V and a temperature range of 0 °C to +70 °C.
Workaround
If the application requires better than +/-4% oscillator accuracy, the voltage
and temperature must be controlled such that they remain within the ranges
given above.
The sink current may drop below 1 µA over temperature and supply voltage.
Workaround
An external pull-down resistor will improve the sink current performance.
