Electrical Specification
3.4.1
Supply Voltage
Following supply voltage is specified at the COM Express® connector:
VCC:
8.5V - 18V
Standby:
5V DC +/- 5%
RTC:
2.5V - 3.3V
- 5V Standby voltage is not mandatory for operation.
- Extended Temperature (E1) variants are validated for 12V supply only
3.4.2
Power Supply Rise Time
» The input voltages shall rise from ≤10% of nominal to within the regulation ranges within 0.1ms to 20ms.
» There must be a smooth and continuous ramp of each DC input voltage from 10% to 90% of its final set-point
following the ATX specification
3.4.3
Supply Voltage Ripple
» Maximum 100 mV peak to peak 0 – 20 MHz
3.4.4
Power Consumption
