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.

STORAGE CONSIDERATIONS

Due to the relatively large package size, 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 to remove moisture prior to

soldering. Sipex ships the 100-pin LQFP in Dry Vapor Barrier

Bags with a humidity indicator card and desiccant pack. The

humidity indicator should be below 30%RH.
