7696D-AVR-06/14 Description This document contains information specific to devices operating at temperatures up to 150°C.

Only deviations are covered in this appendix, all other information can be found in the complete Automotive datasheet. The complete Automotive datasheet can be found on www.atmel.com ATtiny45 Appendix A - ATtiny45 Automotive specification at 150°C DATASHEET ATtiny45 [DATASHEET] 7696DCAVRC06/14

2 1. 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. Parameters Min. Typ. Max.
