3 Detailed Description
3.1 Power Supply / UPS
The CB3053 needs an external power supply of 24V (will tolerate 20V-30V). This input is galvanically
isolated from the board's internal circuitry. It is also used for charging any UPS device that may be
present. This UPS device is either capacitor-based or connected externally as a Pb-battery pack. With a
UPS installed and charged, the module can stay operational even when a power failure occurs. A
capacitor-based UPS can keep the board alive only for a few seconds while a Pb-battery typically allows
for several minutes of continued operation. The exact amount of time is hard to predict as it also depends
on factors such as the UPS' charge level at the time of the power failure, CPU/chipset power consumption
etc. Generally, a Pb-battery needs a much longer time to reach full charge level compared to a
capacitor-based UPS.
3.2 CPU
The motherboard employs an Intel® Atom™ processor either with 1.1GHz or with 1.6GHz clock speed
(Z510/Z530). These are single core CPUs which are optimized for low power consumption while at the
same time providing state-of-the-art computing performance.
The processors include a second level cache of 512 KByte. They also offer many features known from
the desktop range such as MMX2, serial number, loadable microcode etc.
The Atom™ CPU is combined with the SCH US15W chipset. The power consumption of these two
components never exceeds 5 watts combined. Therefore, passive cooling solutions will be sufficient for
many system configurations.
3.3 Memory
There is one conventional SO-DIMM200 socket available to equip the board with memory. For technical
and mechanical reasons it is possible that particular memory modules cannot be employed. Please ask
your sales representative for recommended memory modules.
With currently available SO-DIMM200 modules a memory extension up to 2 GByte is possible
(DDR2-533).
