ARCHITECTURE OVERVIEW
A highly integrated assembly, the Celeron processor mobile
module MMC-2 contains the mobile Celeron processor core
and its immediate system-level support. The Celeron
processor mobile module MMC-2 offers core speeds of 400
megahertz, 366 megahertz, 333 megahertz, and 300
megahertz. All processor speeds have a 66-megahertz
processor system bus speed (PSB).
The PIIX4E/M PCI/ISA Bridge is one of two large-scale
integrated devices of the Intel 440BX AGPset. A notebook’s
system electronics must include a PIIX4E/M device to
connect to the Celeron processor mobile module MMC-2.
The PIIX4E/M provides extensive power management
capabilities and supports the Intel
82433BX Host Bridge,
the second integrated device. Key features of the 82433BX
Host Bridge include the DRAM controller, which supports
EDO at 3.3 volts with a burst read at 7-2-2-2 (60
nanoseconds) or SDRAM at 3.3 volts with a burst read at 8-
1-1-1 (66 megahertz, CL=2). The 82433BX Host Bridge also
provides a PCI CLKRUN# signal to request PIIX4E/M to
regulate the PCI clock on the PCI bus. The 82433BX clock
enables Self Refresh mode of EDO or SDRAM during
Suspend mode and is compatible with SMRAM (C_SMRAM)
and Extended SMRAM (E_SMRAM) modes of power
management. E_SMRAM mode supports write-back
cacheable SMRAM up to 1 megabyte.
A thermal transfer plate (TTP) on the 82433BX Host Bridge
and the CPU provides heat dissipation and a thermal attach
point for the system 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 5 volts to 21 volts, the
processor core voltage regulation enables an above 80
percent peak efficiency and decouples processor voltage
requirements from the system.
The Celeron processor mobile module MMC-2 also
incorporates Active Thermal Feedback (ATF) sensing,
compliant to the
ACPI Specification Rev 1.0
. A system
management bus (SMBus) supports the internal and external
temperature sensing with programmable trip points.
