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 complete ATtiny24/ATtiny44/ATtiny84 automotive datasheet can be

1.Electrical Characteristics
1.1Absolute 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 (2 mA at VCC = 1.8V) under steady state conditions (nontransient), the following must be observed: (1) The sum of all IOL, for all ports, should not exceed 50 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.
4. Although each I/O port can source more than the test conditions (0.5 mA at VCC = 1.8V) under steady state conditions
(nontransient), the following must be observed: (1) The sum of all IOL, for ports B0 to B5, should not exceed 50 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.
