Active 1MHz, VCC = 2V 0.2 0.5 mA Active 4MHz, VCC = 3V 0.8 1.5 mA Active 8MHz, VCC = 5V 2.7 5 mA Power Supply Current(6) Idle 1MHz, VCC = 2V 0.02 0.2 mA ICC Idle 4MHz, VCC = 3V 0.13 0.5 mA Idle 8MHz, VCC = 5V 0.6 1.5 mA WDT enabled, VCC = 3V 4.5 20 µA Power-down mode(7) WDT disabled, VCC = 3V 0.15 10 µA Notes: 1. “Min” means the lowest value where the pin is guaranteed to be read as high. 2. “Max” means the highest value where the pin is guaranteed to be read as low. 3. Although each I/O port can sink more than the test conditions (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state conditions (non-transient), the sum of all IOL (for all ports) should not exceed 60 mA. If IOL exceeds the test conditions, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 4. Although each I/O port can source more than the test conditions (10 mA at VCC = 5V, 5 mA at VCC = 3V) under steady state conditions (non-transient), the sum of all IOH (for all ports) should not exceed 60 mA. If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition. 5. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence, has a weak drive strength as compared to regular I/O pins. 6. Values are with external clock. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive. 7. BOD Disabled.
1.3 Speed
The maximum operating frequency of the device depends on V . As shown in Figure 1-1, the CC relationship between maximum frequency vs. V is linear between 1.8V < V < 4.5V. CC CC
