Although each I/O port can sink more than the test conditions (10mA at VCC = 5V, 5mA at VCC = 3V) under steady state conditions (non-transient), the sum of all IOL (for all ports) should not exceed 60mA. 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. 5. Although each I/O port can source more than the test conditions (10mA at VCC = 5V, 5mA at VCC = 3V) under steady state conditions (non-transient), the sum of all IOH (for all ports) should not exceed 60mA. 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. 6. 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. 7. Values are with external clock. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive. 8. BOD Disabled.

Typical Characteristics The data contained in this section is largely based on simulations and characterization of similar devices in the same process and design methods. Thus, the data should be treated as indications of how the part will behave. The following charts show typical behavior. These figures are not tested during manufacturing. During characterisation devices are operated at frequencies higher than test limits but they are not guaranteed to function properly at frequencies higher than the ordering code indicates. This device has been characterised at temperatures of -40C, 25C, 85C and 125C. All current consumption measurements are performed with all I/O pins configured as inputs and with internal pull-ups enabled. Current consumption is a function of several factors such as operating voltage, operating frequency, loading of I/O pins, switching rate of I/O pins, code executed, and ambient temperature. The dominating factors are operating voltage and frequency. A sine wave generator with rail-to-rail output is used as clock source but current consumption in Power-Down mode is independent of clock selection. The difference between current consumption in Power-Down mode with Watchdog Timer enabled and Power-Down mode with Watchdog Timer disabled represents the differential current drawn by the Watchdog Timer. The current drawn from pins with a capacitive load may be estimated (for one pin) as follows: I CP V CC C L f SW where VCC = operating voltage, CL = load capacitance and fSW = average switching frequency of I/O pin.
