ATtiny13A
Notes: 1. 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 under non-transient, steady state conditions sink more than the test conditions, the sum of all I
OL
(for all ports) should not exceed 60 mA. If I
OL
exceeds the test condition, 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 under non-transient, steady state conditions source more than the test conditions, the sum of all
I
OH
(for all ports) should not exceed 60 mA. If I
OH
exceeds the test condition, V
OH
may exceed the related specification. Pins
are not guaranteed to source current greater than the listed test condition.
7. 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.
8. BOD Disabled.
18.3 Speed
The maximum operating frequency of the device depends on supply voltage, V
CC.
As shown in
Figure 18-1, the relationship between maximum frequency and V
CC
is linear in the range of 1.8V
to 4.5V.
