27. Electrical Characteristics – TA = -40°C to 105°C
Absolute Maximum Ratings*
27.1 DC Characteristics
Notes: 1. “Max” means the highest value where the pin is guaranteed to be read as low
Operating Temperature.................................. -55C to +125C
*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 V
CC
+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
