ATtiny25/ATtiny45/ATtiny85
Appendix B - Automotive Specification at 1.8V
DATASHEET
This document contains information specific to devices operating at voltage between 1.8V
and 3.6V. Only deviations with standard operating characteristics are covered in this
appendix, all other information can be found in the complete Automotive datasheet. The

Electrical Characteristics
1.1
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

2. “Min” means the lowest value where the pin is guaranteed to be read as high
3. Although each I/O port can sink more than the test conditions (0.5mA at VCC = 1.8V) under steady state conditions (nontransient), the following must be observed:
1] The sum of all IOL, for ports B0 - B5, should not exceed 50mA.
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.
4. Although each I/O port can source more than the test conditions (0.5mA at VCC = 1.8V) under steady state conditions
(non-transient), the following must be observed:
1] The sum of all IOH, for ports B0 - B5 should not exceed 50mA.
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.

Maximum Speed vs. VCC
Maximum frequency is dependent on VCC. As shown in Figure 1-1, the maximum frequency versus VCC curve is linear
between 1.8V < VCC < 3.6V.
