Intel Pentium III Mobile module family
Pentium III mobile modules integrate mobile CPU, 82443BX Host bridge
controller and voltage regulator on the same board. 42443BX
controller (part of 440BX AGPset) includes DRAM controller, bus
controller and PCI bus controller. Voltage regulator on the module is
used to convert 12 Volt external voltage into lower voltage for the
82443BX chips and CPU. To interface with the main board the module
uses Mobile Module Connector 2 (MMC-2) - 400-pin connector that was
also used for Celeron and Pentium II mobile modules. CPUs on the
mobile modules have the same features as mobile Pentium III
microprocessors. The CPUs are manufactured using 0.18 micron
technology and have 16 KB code and 16 KB data level 1 caches, on-die
256 KB level 2 cache and 100 MHz Front Side Bus frequency. Many
module processors incorporate SpeedStep feature. Also, mobile
processors include two low-power states that are not present in
desktop microprocessors:
Like the mobile Pentium II processors in microPGA2 and BGA2 packages, the processors in mobile modules include Stop Grant and Sleep low-power modes, but these modes are not supported by modules. Part numbers of mobile modules are different from part numbers of Intel microprocessors. Module names usually starts from "PM". The third letter in the part number tells the type of the CPU: "L" for mobile Pentium III, and "M" for mobile Pentium III with SpeedStep technology. Next three digits are processors speed in Megahertz, and the following two digits signify processor level 2 cache size. Remaining digits and letters in the part number identify module's design revision and processor revision. Production parts
