OPERATING CONDITIONS (Cont’d)
16.3.2 Operating Conditions with Low Voltage Detector (LVD)

Notes:
1. LVD typical data are based on TA=25°C. They are given only as design guidelines and are not tested.
2. Data based on characterization results, not tested in production.
3. The VDD rise time rate condition is needed to insure a correct device power-on and LVD reset. Not tested in production.
4.If the low LVD threshold is selected, when VDD falls below 3.2V, (VDD minimum operating voltage), the device is guar-
anteed to continue functioning until it goes into reset state. The specified VDD min. value is necessary in the device power
on phase, but during a power down phase or voltage drop the device will function below this min. level.
