Architecture Overview
A highly integrated assembly, the Celeron processor mobile module contains the mobile Celeron
processor core with with a 100-MHz processor system bus speed (PSB) and processor speeds of
700 MHz, 650 MHz, 600 MHz, 550 MHz, 500 MHz, and 450 MHz.
The Intel 440BX AGPset provides immediate system-level support for the mobile Celeron
processor 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; the 82443BX Host Bridge also provides 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. E_SMRAM
mode supports write-back cacheable SMRAM up to 1 MB.
The thermal transfer plates (TTP) on the 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.
