Microprocessor
The XB1 COM Express Module is designed for use with Pentium® M and Celeron® M processors
manufactured in 90nm technology (Dothan). These include also the Ultra Low-Voltage (ULV)
Celeron® M and the Low-Voltage (LV) Pentium® M processors as listed below. The processors are
housed in a Micro FC-BGA package for direct soldering to the PCB, i.e. the CPU chip cannot be
removed or changed by the user.
The processors supported by the XB1 COM Express Module are running at FSB clock speeds of
400MHz and 533MHz. The internal Pentium M processor speed is achieved by multiplying the host
bus frequency by a variable value. The multiplier is chosen by currently required performance and the
actual core temperature. This technology is called Enhanced Intel SpeedStep®.
Power is applied across the COM Express connectors J-COM (+12V). The processor core voltage is
generated by a switched voltage regulator. The processor signals its required core voltage by 6
dedicated pins according to Intels IMVP-IV voltage regulator specification.

This processor does not support SpeedStep® technology, instead it runs at a fixed core speed
2)
Following the Intel Embedded Roadmap, this processor is recommended for long time availability
