12.2.3 Thermal Characteristics
12.3 OPERATING CONDITIONS
12.3.1 General Operating Conditions (standard voltage ROM and Flash devices)
.
Figure 55. fCPU Versus VDD for standard voltage devices
12.3.2 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for VDD, fCPU, and TA. Refer to Figure 15 on page 21.
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.
