ATmega8(L)
Electrical Characteristics – TA = -40°C to 85°C
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*
*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.
