Functional Description

Lithium batteries incorporate inflammable materials

! such as lithium and organic solvents. If lithium batteries

Caution 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.

❏Do not charge.

❏Always check proper polarity.

To remove the battery from the module, carefully pull the battery from the socket. (Data will be lost if a new battery is not installed within 30 seconds.)

Before installing a new battery, ensure that the battery pins are clean. Note the battery polarity and press the battery into the socket.

Onboard DRAM

The MVME187 onboard DRAM is located on a mezzanine board. The mezzanine boards are available in different sizes and with parity protection or ECC protection.

Note Parity mezzanines are only supported on 25 MHz main boards.
