An optional external battery, connected at J8 , supplies the PCM-VDX-2-512 board with standby power for the real-time
clock and CMOS setup RAM. An extended temperature lithium battery is available from WinSystems, part number
BAT-LTC-E-36-16-1 or BAT-LTC-E-36-27-1.
A power supervisory circuit contains the voltage sensing circuit and an internal power switch to route the battery
or standby voltage to the circuits selected for backup. The battery automatically switches ON when the VCC of the
systems drops below the battery voltage and back OFF again when VCC returns to normal.
For OEM applications, an on-board battery may be populated. Please contact your WinSystems’ Application Engineer
for additional information.
(For external battery. Provides battery backup to RTC and BIOS CMOS.)
