13.3 OPERATING CONDITIONS
13.3.1 General Operating Conditions
Figure 42. fCPU Maximum Operating Frequency Versus VDD Supply Voltage
13.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for VDD, fCPU, and TA. Refer to Figure 9 on page 20.
Notes:
1. The VDD rise time rate condition is needed to insure a correct device power-on and LVD reset. Not tested in production.
2. Guaranteed by characterization - not tested in production
