Functional Description
4.1
Celeron Processor Mobile Module
The Celeron processor mobile module offers processor speeds of 650 MHz, 600 MHz, 550 MHz,
500 MHz, and 450 MHz with a 100-MHz PSB.
4.2
L2 Cache
The on-die L2 cache is 128K, four-way set associative, and runs at the speed of the processor core.
4.3
The 82443BX Host Bridge System Controller
Intel's 82443BX Host Bridge system controller is a highly integrated device that combines the bus
controller, the DRAM controller, and the PCI bus controller into one component. The 82443BX
Host Bridge has multiple power management features designed specifically for notebook systems
such as:
CLKRUN#, a feature that enables controlling of the PCI clock on or off.
The 82443BX Host Bridge suspend modes, which include Suspend-To-RAM (STR), Suspend-
To-Disk (STD), and Power-On-Suspend (POS).
System Management RAM (SMRAM) power management modes, which include Compatible
SMRAM (C_SMRAM) and Extended SMRAM (E_SMRAM). C_SMRAM is the traditional
SMRAM feature implemented in all Intel PCI chipsets.
E_SMRAM is a new feature that supports write-back cacheable SMRAM space up to 1 MB.
To minimize power consumption while the system is idle, the internal 82443BX Host Bridge
clock is turned off (gated off) when there is no processor and PCI activity. This is
accomplished by setting the G_CLK enable bit in the power management register in the
82443BX through the system BIOS.
4.3.1
Memory Organization
The memory interface of the 82443BX Host Bridge is available at the connector. This allows for
the following:
One set of memory control signals, sufficient to support up to three SO-DIMM sockets and six
banks of SDRAM at 100 MHz.
One CKE signal for each bank.
Memory features
not
supported by the 82443BX Host Bridge system controller standard MMC-2
mode are:
Eight banks of memory
256-Mb memory devices
Second set of memory address lines (MAA[13:0])
