Appendix B - ATtiny25/45/85 Automotive Specification at 1.8V Preliminary

Product catalog summary

Introduction
This document is an appendix to the ATtiny25/45/85 automotive datasheet, focusing on devices operating at voltages between 1.8V and 3.6V. It highlights deviations from standard operating characteristics.

Electrical Characteristics

Absolute Maximum Ratings: Operating temperature ranges from -55°C to +150°C. Storage temperature ranges from -65°C to +175°C. Maximum operating voltage is 6.0V.
DC Characteristics: Input and output voltage levels are specified for various pins, with specific conditions for low and high voltage thresholds.
Power Supply Current: Active mode at 4MHz and VCC = 1.8V consumes 0.8 to 1 mA. Idle mode consumes 0.2 to 0.3 mA, and power-down mode varies depending on WDT status.

Performance Characteristics

Maximum Speed vs. VCC: The maximum frequency is linearly dependent on VCC, ranging from 1.8V to 3.6V.
ADC Characteristics: The ADC has an 8-bit resolution with specified accuracy, non-linearity, and error parameters. Conversion time and clock frequency are also detailed.

Ordering Information
Devices are available in different memory sizes (2KB, 4KB, 8KB) and are suitable for automotive applications with an operational range of -40°C to +85°C.

Disclaimer
The document includes a disclaimer regarding the use of Atmel products, emphasizing no liability for damages and no warranty for specific applications.
