The Celeron processor mobile module MMC-1 is a highly
integrated assembly containing the mobile Celeron
processor and its immediate system-level support. The
Celeron processor mobile module MMC-1 offers speeds of
400 megahertz,366 megahertz, 333 megahertz, 300
megahertz, and 266 megahertz. All processor speeds have
a 66-megahertz processor system bus (PSB) speed.
Date
Avoids complexities associated with designing high-
speed processor core logic boards.
Provides an upgrade path from previous Intel
Modules using a standard interface.

The PIIX4E/M PCI/ISA Bridge is one of two large-scale
integrated devices of the Intel 440DX PCIset. A notebook’s
system electronics must include a PIIX4E/M device to
connect to the Celeron processor mobile module. The
PIIX4E/M provides extensive power management
capabilities and supports the second integrated device, the
Intel 82443DX Host Bridge. Key features of the Intel
82443DX Host Bridge system controller 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 82443DX Host Bridge also regulates the PCI clock on
the PCI bus. The 82443DX 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 82443DX Host Bridge
and the CPU provides heat dissipation and a thermal attach
point for the notebook 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 regulator enables an above 80
percent peak efficiency and decouples processor voltage
requirements from the system.
The Celeron processor mobile module MMC-1 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.
