OPERATING CONDITIONS (Cont’d)
12.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for V
Notes:
1. Data based on characterization results, tested in production for ROM devices only.
2. If the medium or low thresholds are selected, the detection may occur outside the specified operating voltage range.
Below 3.8V, device operation is not guaranteed.
3. Data based on characterization results, not tested in production.
12.3.3 Auxiliary Voltage Detector (AVD) Thresholds
Subject to general operating conditions for V
1. Data based on characterization results, tested in production for ROM devices only.
12.3.4 External Voltage Detector (EVD) Thresholds
Subject to general operating conditions for V
1. Data based on characterization results, not tested in production.
