The Emerson Network Power COMX-315 is a Compact COM Express® module based on the
Intel® Atom™ processor E640 for deeply embedded, low power applications. At 95 mm x
95 mm, compact format COM Express modules are designed to integrate all the core
components of a common PC in a form factor small enough for specic embedded
applications on a carrier board. COMX-315 includes graphics, sound, storage, network
and multiple USB ports. The COMX-315 will be Type 2 compatible to t on existing Type
2 carriers, but will not include the legacy PCIbus and IDE parallel interfaces.
Based on the Intel Atom processor E640, the COMX-315 module is a highly reliable and
long lifecycle product with ultra low power consumption, making it ideal for portable
and hand held applications that do not require forced-air cooling. In addition, COMX-
315 is designed to operate in an extended temperature environment which means it
can be deployed in outside equipment reliably and efciently. Typical applications for
COMX-315 include portable test equipment, handheld devices and mobile based
applications.
