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.

A = -40°C to +85°C; VSS = 0V;

CC =2.7V to 5.5V and F = 0 to 40 MHz (both internal and external code execution)

CC =4.5V to 5.5V and F = 0 to 60 MHz (internal code execution only)
