Electrical Characteristics
Absolute Maximum Ratings*
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only
and functional operation of the device at these
or other conditions beyond those indicated in
the operational sections of this specification is
not implied. Exposure to absolute maximum rat-
ing conditions for extended periods may affect
device reliability.

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 V
CC
= 5V, 5 mA at V
CC
= 3V) under steady
state conditions (non-transient), the sum of all I
OL
(for all ports) should not exceed 60 mA. If I
OL
exceeds the test con-
ditions, V
OL
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 V
CC
= 5V, 5 mA at V
CC
= 3V) under steady
state conditions (non-transient), the sum of all I
OH
(for all ports) should not exceed 60 mA. If I
OH
exceeds the test con-
dition, V
OH
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.
