33. Electrical Characteristics
33.1 Absolute Maximum Ratings
Table 33-1. 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
DC Current per I/O Pin 40.0 mA
DC Current VCC and GND Pins 100.0 mA
Note: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage
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.
Note: During parallel programming, a 12V signal is connected to the Reset pin. There is therefore no
internal protection diode from the Reset pin to V
CC
. To achieve the same protection on the Reset pin as
on other I/O pins external protection should be added.
