Board Level Hardware Description

with the board powered off and the board at 40° C. If the power-on duty cycle is 50% (the board is powered on half of the time), the battery lifetime is four years. At lower ambient temperatures the backup time is greatly extended and may approach the shelf life of the battery. When a board is stored, the battery should be disconnected to prolong battery life. This is especially important at high ambient temperatures. The MVME166 is shipped with the batteries disconnected.

The power leads from the battery are exposed on the solder side of the board, therefore the board should not be placed on a conductive surface or stored in a conductive bag unless the battery is removed.

Caution

Lithium batteries incorporate inflammable materials such as lithium and organic solvents. If lithium batteries are mistreated or handled incorrectly, they may burst open and ignite, possibly resulting in injury and/or fire. When dealing with lithium batteries, carefully follow the precautions listed below in order to prevent accidents.

❏Do not short circuit.

❏Do not disassemble, deform, or apply excessive pressure.

❏Do not heat or incinerate.

❏Do not apply solder directly.

❏Do not use different models, or new and old batteries together.

❏Do not charge.

❏Always check proper polarity.

To remove the battery from the module, carefully pull the battery from the socket.

Before installing a new battery, ensure that the battery pins are clean. Note the battery polarity and press the battery into the socket. When the battery is in the socket, no soldering is required.

Onboard DRAM

The MVME166 onboard DRAM is located on a mezzanine board. The mezzanine boards are available in different sizes and with ECC protection. Mezzanine board sizes are 4, 8, 16, 32, 64, or 128MB, and two mezzanine boards may be stacked to provide 256MB of onboard RAM. The main board and a single mezzanine board together take one slot. The stacked configuration requires two VMEboard slots. The DRAM is four-way interleaved to efficiently support cache burst cycles.
