OPERATING CONDITIONS (Cont’d)
10.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for V
DD
, f
OSC
, and T
A
.
Notes:
1. LVD typical data are based on T
A
=25°C. They are given only as design guidelines and are not tested.
2. The minimum V
DD
rise time rate is needed to insure a correct device power-on and LVD reset. Not tested in production.
3. Data based on characterization results, not tested in production.
