Stresses above these listed maximum ratings may cause permanent damage to the device.
Exposure beyond specified electrical characteristics may affect device reliability or cause malfunction.
21.2 Handling Procedures
This device has built-in protection against high static voltages or electric fields; however, anti-static
precautions should be taken as for any other CMOS component.
Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the
supply voltage range.

Note 1:
The minimum V
DD
of 2.0V allows proper system functionality for the core Logic and the EEPROM,
However the ADC minimum voltage is > 2.6V for full range conversion and 0.2 LSB error.
Note 2:
This capacitor filters switching noise from V
DD
to keep it away from the internal logic cells.
In noisy systems the capacitor should be chosen bigger than minimum value.
