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 func-
tional operation of the device at these or any other
conditions above those indicated in the operational
sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions may
affect device reliability.
Power dissipation value is based on the maximum
allowable die temperature and the thermal resis-
tance 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)
