Appendix A and B – ATtiny261A Specification at 105°C and 125°C
This document contains information specific to devices operating at temperatures up to
125В°C. Only deviations are covered in this appendix, all other information can be found in
the complete datasheet. The complete datasheet can be found at www.atmel.com. Rev. 8197E–AVR–11/2014 Atmel-8197E-AVR-ATtiny261A-Specification-at-105°C-and-125°C-Datasheet_11/2014 1. Electrical Characteristics
1.1 Absolute Maximum Ratings* Operating Temperature .-55п‚°C to +125п‚°C *NOTICE: Storage Temperature .-65п‚°C to +150п‚°C
Voltage on any Pin except RESET
with respect to Ground . -0.5V to VCC+0.5V
Voltage on RESET with respect to Ground . -0.5V to +13.0V 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 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. Maximum Operating Voltage .6.0V
