11.3 OPERATING CONDITIONS

11.3.1 General Operating Conditions

Figure 30. fCPU Maximum Operating Frequency Versus VDD Supply Voltage

11.3.2 Operating Conditions with Low Voltage Detector (LVD)

Subject to general operating conditions for VDD, fCPU, and TA. Refer to Figure 11 on page 14.

Notes:

1. Not tested, guaranteed by design.

2. Not tested in production, guaranteed by characterization.

3. The VDD rise time rate condition is needed to insure a correct device power-on and LVD reset. Not tested in production.
