Note: 1. These values are based on simulation and characterization of other AVR microcontrollers
manufactured in the same process technology. These values are not covered by test limits in
production.
7.3 Maximum Clock Frequencies
These parameters are given in the following conditions:
•V
VDDCORE
= 1.62V to 1.98V
• Temperature = -40°C to 85°C
7.4 Power Consumption
The values in Table 7-5 are measured values of power consumption under the following condi-
tions, except where noted:
• Operating conditions internal core supply (Figure 7-1) - this is the default configuration
–V
VDDIN
= 3.0V
–V
VDDCORE
= 1.62V, supplied by the internal regulator
