Typical values at +25C. 2. “Max” means the highest value where the pin is guaranteed to be read as low. 3. “Min” means the lowest value where the pin is guaranteed to be read as high. 4. Not tested in production. 5. 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 100 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. 6. 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 100 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. 7. 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. See “Output Driver Strength” on page 20. 8. These are test limits, which account for leakage currents of the test environment. Actual device leakage currents are lower. 9. Values are with external clock using methods described in “Minimizing Power Consumption” on page 39. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive. 10. Bod Disabled.
