DC Parameters for Standard Voltage
I = industrial ........................................................-40°C to 85°C
Storage Temperature .................................... -65°C to + 150°C
Voltage on VCC to VSS ......................................-0.5V to + 6.5V
VVoltage on Any Pin to VSS .......................-0.5V to VCC + 0.5V
Power Dissipation ........................................................... 1 W(2)
Note:
Stresses at or above 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 any other condi-
tions above those indicated in the operational
sections of this specification is not implied. Exposure
to absolute maximum rating conditions may affect
device reliability.
Power dissipation is based on the maximum allow-
able die temperature and the thermal resistance of
the package.
TA = -40°C to +85°C; VSS = 0V;
VCC =2.7V to 5.5V and F = 0 to 40 MHz (both internal and external code execution)
VCC =4.5V to 5.5V and F = 0 to 60 MHz (internal code execution only)
