10.3.6 VBAT (System Battery Connection)
•
This pin connects a system battery to all modules.
•
The battery voltage has to be higher than 2.85V and lower than 3.15V. Kontron
Embedded Modules recommends a 3V battery (for example, CR2032).
Note:
There is no battery needed to hold CMOS-setup data. Your configuration
information is saved in an onboard Ferroelectric Random-Access Memory (FRAM.)
However, you need a battery to run the CMOS date and time when power
consumption is off.
10.3.7 POWERGOOD (Reset Input 2)
•
Input on CPU modules
•
Open collector output on all other modules
•
When POWERGOOD goes high, it starts the reset generator on the CPU module
to pull the onboard reset line high after a valid reset period. You also can use this
pin as a low active hardware reset for modules.
