Handling, PCB Layout, and Assembly

The 1339 package contains a quartz tuning-fork crystal. Pick-and-place equipment may be used, but precautions should be

taken to ensure that excessive shocks are avoided. Ultrasonic cleaning equipment should be avoided to prevent damage to

the crystal.

Avoid running signal traces under the package, unless a ground plane is placed between the package and the signal line.

All NC (no connect) pins must be connected to ground.

Moisture-sensitive packages are shipped from the factory dry-packed. Handling instructions listed on the package label must

be followed to prevent damage during reflow. Refer to the IPC/JEDEC J-STD-020 standard for moisture-sensitive device

(MSD) classifications.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the 1339. These ratings, which are

standard values for Renesas commercially rated parts, are stress ratings only. Functional operation of the device at

these or any other conditions above those indicated in the operational sections of the specifications is not implied.

Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical

parameters are guaranteed only over the recommended operating temperature range.

Recommended DC Operating Conditions

Note A: Operating voltages without a back up supply connected.

Note B: When a back up supply voltage is connected choose proper part number 1339-2 or 1339-31 depending

upon the back up supply voltage.
