User’s Manual for Advantech SOM-A2558 series module V1.00

answer in the 3rd mechanical drawing. Maximum height of SOM module allied with CSB is 5.20mm. One port USB 1.1 host connector height is 8.37mm, 1 DB-9 RS-232 connector is 12.53mm, 1 type-II CF slot is 8.72mm. So, this is the answer! If users want to use any standard I/O connector on CSB, then SOM structure is not the maximum height maker. The maximum highness is decided by I/O connector, not SOM structure.

1.2.3 Power Consumption

In WinCE O.S. environment, SOM-A2558 series products have 3 kinds of operating model :

Normal mode: I/O and system all work well. All components on SOM-A55x are powered.

Idle mode: I/O and system all work well except backlight control circuit. In order to do power-saving, LCD backlight control circuit will disable the LCD backlight inverter.

Suspend mode: all devices are no-powered except SDRAM, RTC(real time clock) & some CPU(PXA255) power pins. In suspend mode, SOM-A255x series are only powered by BAT_VCC pin ( Li-ion 3.0V coin battery from CSB).If user doesn’t design coin battery to power BAT_VCC pin, then Suspend mode doesn’t work on SOM-A55x series products.
