ATMEGA8_08 Datasheet, PDF (242/308 Pages) ATMEL Corporation – 8-bit with 8K Bytes In-System Programmable Flash

Electrical Characteristics
Note: Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manu-
factured on the same process technology. Min and Max values will be available after the device is characterized.
Absolute Maximum Ratings*
Operating Temperature.................................. -55°C to +125°C
Storage Temperature ..................................... -65°C to +150°C
Voltage on any Pin except RESET
with respect to Ground ................................-0.5V to V_CC+0.5V
Voltage on RESET with respect to Ground......-0.5V to +13.0V
Maximum Operating Voltage ............................................ 6.0V
*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.
DC Current per I/O Pin ............................................... 40.0 mA
DC Current V_CC and GND Pins................................ 300.0 mA
