8197C–AVR–05/11

ATtiny261A/461A/861A

Notes:

1. Typical values at +25

°C.

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. Although each I/O port can sink more than the test conditions (10 mA at V

CC = 5V, 5 mA at VCC = 3V) under steady state

conditions (non-transient), the sum of all IOL (for all ports) should not exceed 100 mA. If IOL exceeds the test conditions, VOL

may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition.

5. Although each I/O port can source more than the test conditions (10 mA at V

CC = 5V, 5 mA at VCC = 3V) under steady state

conditions (non-transient), the sum of all IOH (for all ports) should not exceed 100 mA. If IOH exceeds the test condition, VOH

may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition.

6. 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 20-32, Figure 20-33, Figure 20-34, and Figure 20-35

(starting on page 214).

7. Values are with external clock using methods described in “Minimizing Power Consumption” on page 37. Power Reduction is

enabled (PRR = 0xFF) and there is no I/O drive.

8. BOD Disabled.
