Notes: 1. Typical values at 25C.

3. “Max” means the highest value where the pin is guaranteed to be read as low.
4. Not tested in production.
5. Although each I/O port can sink more than the test conditions (10 mA at V
state conditions (non-transient), the sum of all I
ditions, V
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test
OL
condition.
6. Although each I/O port can source more than the test conditions (10 mA at V
state conditions (non-transient), the sum of all I
dition, V
may exceed the related specification. Pins are not guaranteed to source current greater than the listed test
OH
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 figures, for ATtiny24A, from Figure 3-22 on
page 21 to Figure 3-25 on page 23, and for ATtiny44A, from Figure 3-67 on page 44 to Figure 3-70 on page 45.
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”. Power reduction is
enabled (PRR = 0xFF) and there is no I/O drive.
10.BOD disabled.

2.4.1 Accuracy of Calibrated Internal Oscillator
It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration. Note that
oscillator frequency depends on temperature and voltage. Voltage and temperature characteristics can be found in
