3.5. Processor Support
The ECX-BYT is designed to support Intel® Bay Trail SoC Processors. The BGA CPU is remounted 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.

Celeron® J1900

Atom™ E3825
2 1.33 GHz - Yes 1M FCBGA1170 6 W -40 °C ~ 110 °C
Celeron® N2807 2 1.58 GHz 2.16 GHz Yes 1M FCBGA1170 4.3 W 105 °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.
3.6. System Memory Support
The ECX-BYT has one DDR3L SO-DIMM socket. The sockets support the following memory features:
 1x DDR3L SO-DIMM 204-pin
 Up to 4GB (for model with Celeron® N2807)
 Up to 8GB (for other models)
 SPD timing supported
 ECC not supported
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, or the board may not be able to
boot totally.
3.6.1. Memory Operating Frequencies
In all modes, the frequency of system memory is the lowest frequency of all the memory modules placed in the
system. Each memory module's frequency can be determined through the SPD registers on the memory modules.
The table below lists the resulting operating memory frequencies based on the combination of SO-DIMMs and
processor.
