7.3 Maximum Clock Frequencies
These parameters are given in the following conditions:
•V
VDDCORE
> 1.85V
• Temperature = -40°C to 125°C
Note: 1. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-
cess technology. These values are not covered by test limits in production.
7.4 Power Consumption
The values in Table 7-4 are measured values of power consumption under the following condi-
tions, except where noted:
• Operating conditions core supply (Figure 7-1)
–V
VDDIN_5
= V
VDDIN_33
= 3.3V
–V
VDDCORE
= 1.85V, supplied by the internal regulator
–V
VDDIO1
= V
VDDIO2
= V
VDDIO3
= 3.3V
–V
VDDANA
= 3.3V
