Notes: 1. Typical values at 25C.
2. “Min” means the lowest value where the pin is guaranteed to be read as high.
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 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 con-ditions, 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 60 mA. If IOH exceeds the test con-dition, 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 conse-quence, 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.

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 Figure 3-45 on page 33.
