Introduction
Using Intel’s advanced 0.13-micron process technology with copper interconnect, the Mobile Intel
Pentium III Processor-M offers high-performance and low-power consumption. The Mobile Intel
Pentium III Processor-M (hereafter referred to as “the processor”) is based on the same core as existing
Mobile Intel Pentium III processors. Key performance features include Internet Streaming SIMD
instructions, an Advanced Transfer Cache architecture, and a processor system bus speed of 133 MHz.
These features are offered in Micro-FCPGA packages for socketable boards and Micro-FCBGA
packages for surface mount boards.
The Low Voltage Mobile Intel Pentium III Processor-M will support both a 133-MHz and 100-MHz
bus speed. The Ultra Low Voltage Mobile Intel Pentium III Processor-M will support both 133-MHz
and 100-MHz (see product features section for specific supported frequencies) bus speed. The Low
Voltage and Ultra Low Voltage Mobile processors will be available only in the Micro-FCBGA
package. All of these technologies make outstanding performance possible for mobile PCs in a variety
of shapes and sizes.
The processor, when used in conjunction with the Intel SpeedStep technology applet version 2.1
(contact your Intel Field Sales Representative) or its equivalent, supports Enhanced Intel SpeedStep
technology, which enables real-time dynamic switching of the voltage and frequency between two
performance modes based on CPU demand. This occurs by switching the bus ratios, core operating
voltage, and core processor speeds without resetting the system. The processor also features a new
ultra low power state called Deeper Sleep.
The 512-kB integrated L2 cache based on the Advanced Transfer Cache architecture runs at full speed
and is designed to help improve performance. It complements the system bus by providing critical data
faster and reducing total system power consumption. The processor also features Data Prefetch Logic
that speculatively fetches data to the L2 cache, resulting in improved performance. The Mobile
Pentium III Processor-M’s 64-bit wide Assisted Gunning Transceiver Logic (AGTL) system bus
provides a glue-less, point-to-point interface for a memory controller hub.
