22. Electrical Characteristics

22.1

Absolute Maximum Ratings*

Operating Temperature.................................. -40°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 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

DC Current

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