3.3. Processor Support Table
mITX-BW is designed to support the Braswell Celeron processors. The BGA CPU is premounted from factory. Kontron
has defined the board versions as listed in the following table, so far all based on Embedded CPUs. Other versions are
expected at a later date.
Table 3: Processor Support
mITX-BW Variants CPU TDP / Tj
Name Sales PN Speed Embedded Cache
mITX-BW N3710 810620-4500 1.6 GHz 4 core Yes 2 MByte 6 W / 90°C
mITX-BW N3160 810621-4500 1.6 GHz 4 core Yes 2 MByte
6 W / 90°C
mITX-BW N3060 810622-4500 1.6 GHz 2 core Yes 2 MByte 6 W / 90°C
Sufficient cooling must be applied to the CPU in order to remove the effect as listed as TDP (Thermal Design Power) in
above table. The sufficient cooling is also depending on the worst case maximum ambient operating temperature and
the actual worst case load of processor.
The mITX-BW is delivered with premounted heatsink.

mITX-BW – User Guide, Rev. 1.6

3.4. System Memory Support
The mITX-BW has two DDR3L SO-DIMM sockets. The sockets support the following memory features:
2x DDR3L 1.35 V SO-DIMM 204-pin
Dual-channel with 1 SO-DIMM per channel
From 1 GByte and up to 2x 4 GByte.
Single/dual rank unbuffered 1333/1600MT/s (PC3-10600/PC3-12800)
SPD timings supported
ECC not supported
If only one SO-DIMM is used, then slot J24 must be used as the primary slot (ChannelA).
If Slot J25 (Channel B) is populated, then the board will not boot.
If using 32bit OS then less than 4GB in displayed in System (Shared Video Memory/PCI
resources is subtracted). Use SO-DIMM with the same memory density in both sockets!
The installed DDR3L SO-DIMM should support the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read and configure the memory controller for optimal performance. If non-SPD memory is used, the BIOS will attempt
to configure the memory settings, but performance and reliability may be impacted.
Memory Operating Frequencies
Regardless of the SO-DIMM type used, the memory frequency will either be equal to or less than the processor
system bus frequency. For example, if DDR3L 1600 memory is used with a 1333 MHz system bus frequency processor,
the memory clock will operate at 167 MHz. The table below lists the resulting operating memory frequencies based on
the combination of SO-DIMMs and processor.

Kontron offers the following memory modules:
2 GByte DDR3L 1600 PC3-12800, P/N: 1060-2520
4 GByte DDR3L 1600 PC3-12800, P/N: 1060-2522
8 GByte DDR3L 1600 PC3-12800, P/N: 1060-2524
Memory modules have in general a much lower longevity than embedded motherboards, and therefor EOL of
modules can be expected several times during lifetime of the motherboard. Kontron guarantees that the above P/N
will be maintained so that EOL module will be replaced by other similar type of qualified module.
As a minimum it is recommend using Kontron memory modules for prototype system(s) in order to prove stability of
the system and as for reference.
For volume production you might request to test and qualify other types of RAM. In order to qualify RAM it is
recommend configuring 3 systems running RAM Stress Test program in heat chamber at 60° C for a minimum of 24
hours.
