Architecture Overview
A highly integrated assembly, the Pentium
III
processor mobile module featuring Intel SpeedStep
technology contains the mobile Pentium
III
processor core that runs at speeds of 750/600 MHz,
700/550 MHz, 650/500, and 600/500 MHz with a 100-MHz processor system bus speed (PSB).
The Intel 440BX AGPset provides immediate system-level support and includes the PIIX4E/M
PCI/ISA Bridge and the 82443BX Host Bridge. The PIIX4E/M provides extensive power
management capabilities and supports the Intel 82443BX Host Bridge. A notebook’s system
electronics must include a PIIX4E/M device to connect to the mobile module.
Key features of the Intel 82443BX Host Bridge include: the DRAM controller supporting SDRAM
at 3.3Vwith a burst read at 4-1-1-1; a PCI CLKRUN# signal to request the PIIX4E/M to regulate
the PCI clock on the PCI bus; the 82443BX clock enables Self-Refresh mode of SDRAM during
Suspend mode and is compatible with SMRAM (C_SMRAM) and Extended SMRAM
(E_SMRAM) modes of power management; and E_SMRAM mode supports write-back cacheable
SMRAM up to 1 MB.
The TTPs on the mobile Pentium
III
processor and the 82443BX Host Bridge provide heat
dissipation and thermal attach points for the manufacturer’s thermal solution.
An on-board voltage regulator converts the system DC voltage to the processor’s core and I/O
voltage. Isolating the processor voltage requirements allows the system manufacturer to
incorporate different processor variants into a single notebook system. Supporting input voltages
from 7.5V to 21.0V, the integrated module voltage regulator enables an above 80% peak efficiency
and de-couples the processor voltage requirements from the system.
Also incorporated is active thermal feedback (ATF) sensing, compliant to the
ACPI Specification
Rev 1.0.
An integrated system management bus (SMBus) compliant thermal sensor supports the
internal and external temperature sensing with programmable trip points.
