PACKAGE CHARACTERISTICS (Cont’d)
13.2 THERMAL CHARACTERISTICS
Notes:
1. The maximum chip-junction temperature is based on technology characteristics.
2. The maximum power dissipation is obtained from the formula P
The power dissipation of an application can be defined by the user with the formula: P
where P
the ports used in the application.
