ATtiny261/ATtiny461/ATtiny861

Notes:

1. All DC Characteristics contained in this data sheet are based on simulation and characterization of ATtiny261/461/861 AVR

microcontrollers manufactured in a typical process technology. These values are preliminary values representing design tar-

gets, and will be updated after characterization of actual Automotive silicon.

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. 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 following must be observed:

1] The sum of all IOL, for all ports, should not exceed 60 mA.

If IOL exceeds the test condition, 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 VCC = 5V, 5 mA at VCC = 3V) under steady state

conditions (non-transient), the following must be observed:

1] The sum of all IOH, for all ports, should not exceed 60 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. Values using methods described in “Minimizing Power Consumption” on page 36. Power Reduction is enabled (PRR =

0xFF) and there is no I/O drive.

7. BOD Disabled.
