ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability.

Power Dissipation per package
80-pin QFP (derate 18.3mW/°C above +70°C)..1500mW
STORAGE CONSIDERATIONS
Due to the relatively large package size of the 80-pin
quad flat-pack, storage in a low humidity environment
is preferred. Large high density plastic packages are
moisture sensitive and should be stored in Dry Vapor
Barrier Bags. Prior to usage, the parts should remain
bagged and stored below 40°C and 60%RH. If the parts
are removed from the bag, they should be used within
48 hours or stored in an environment at or below 20%RH.
If the above conditions cannot be followed, the parts
should be baked for four hours at 125°C in order
remove moisture prior to soldering. Exar ships the 80-
pin LQFP in Dry Vapor Barrier Bags with a humidity
indicator card and desiccant pack. The humidity indicator
should be below 30%RH.
