Due to the relatively large package size of the 100-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

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
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. Exar 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.
