OPERATING CONDITIONS (Cont’d)
12.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for VDD,fCPU, and TA.
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. Applicable only in low voltage devices (planned).
4. The VDD rise time rate condition is needed to insure a correct device power-on and LVD reset. Not tested in production.
12.3.3 Auxiliary Voltage Detector (AVD) Thresholds
Subject to general operating condition for VDD,fCPU, and TA.
1. AVD 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. Applicable only in low voltage devices (planned).
