20.1

Absolute Maximum Ratings*

20.2

DC Characteristics

Note:

All DC Characteristics contained in this data sheet are based on simulation and characterization of other AVR microcontrollers

manufactured in the same process technology. These values are preliminary values representing design targets, and will be

updated after characterization of actual silicon.

Operating Temperature.................................. -55

°C to +125°C

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age 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.

Storage Temperature ..................................... -65°C to +150°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

Maximum Operating Voltage ............................................ 6.0V

DC Current per I/O Pin ............................................... 40.0 mA

DC Current

CC and GND Pins ................................ 200.0 mA
