Notes:
1. Typical values at 25
°C.
2. “Max” means the highest value where the pin is guaranteed to be read as low.
3. Not tested in production.
4. “Min” means the lowest value where the pin is guaranteed to be read as high.
5. Although each I/O port can under steady state (non-transient) conditions sink more than indicated, the sum of all I
OL currents
may not exceed 60 mA, or the boost converter limits. If IOL limits are exceeded the corresponding VOL levels can not be guar-
anteed. Pins are not guaranteed to sink currents greater than those listed.
6. Pins PB1, PB2, PB4 and PB5 are high sink I/O pins.
7. Although each I/O port can under steady state (non-transient) conditions source more than indicated, the sum of all IOH cur-
rents may not exceed 60 mA, or the boost converter limits. If I
OH limits are exceeded the corresponding VOH levels can not
be guaranteed. Pins are not guaranteed to source currents greater than those listed.
8. 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 Figure 21-31 on page 184 and Figure 21-32 on page 184.
9. Values are with external clock using methods described in “Minimizing Power Consumption” on page 32. Power Reduction
is enabled (PRR = 0xFF) and there is no I/O drive.
10. See “Boost Converter Characteristics” on page 162 for current consumption of entire device, including boost converter.
11. BOD Disabled.
