Appendix B - ATtiny24V/ATtiny44V/ATtiny84V Automotive Specification at 1.8V 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 found on www.atmel.com 8-bit Microcontroller with 2/4/8K Bytes In-System Programmable Flash ATtiny24V ATtiny44V ATtiny84V Appendix B Preliminary 7819A–AVR–01/09 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 Value Unit Operating temperature –40 to +85 °C Storage temperature –65 to +175 °C –0.5 to VCC + 0.5 V Voltage on any pin except RESET with respect to ground Maximum operating voltage 6.0 V DC current per I/O pin 30.0 mA DC current VCC and GND pins 200.0 mA 1.2 DC Characteristics TA = –40° C to +85° C, VCC = 1.8V to 3.6V (unless otherwise noted) Symbol Parameters Condition Min.

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. 2 ATtiny24V/ATtiny44V/ATtiny84V [Preliminary] 7819A–AVR–01/09 ATtiny24V/ATtiny44V/ATtiny84V [Preliminary] 1.3 Maximum Speed versus VCC Maximum frequency is dependent on VCC.
