INTRODUCTION
The Intel Pentium
processor with MMX
technology Mobile Module is the fundamental
building block for a system manufacturer to
incorporate into a notebook system. The Intel
Mobile Module incorporates an Intel mobile
Pentium Processor with MMX technology,
second-level
cache,
Northbridge system controller, voltage regulator,
and thermal sensor on a single printed circuit
board.

430TX
PCIset
Intel’s PCIset architecture allows for physical
partitioning at both the PCI and DRAM interfaces;
therefore the electrical interconnect defined for the
Intel Mobile Module includes the PCI bus, DRAM
memory bus and some PCIset sideband signals.
An onboard voltage regulator provides the DC
conversion from the system manufacturer’s
system DC voltage to the processor’s core voltage
and the 2.5V CPU interface signals. This isolation
of the processor voltage requirements allows the
system manufacturer to incorporate Intel Mobile
Modules with different processor variants into a
notebook system.
Building around this modular design gives the
system manufacturer these advantages:
Avoids complexities associated with designing
high-speed processor core logic boards
No requirement for manufacturing capabilities
of Tape Carrier Package (TCP) processors
Future Intel Mobile Modules provide an
upgrade path for notebook designs using a

Eliminates the need to design for unique

succeeding
The 430TX PCIset (Northbridge) is one of two
physical VLSI devices that constitute the Intel
430TX PCIset controller. The second 430TX
device (Southbridge) is known as the PIIX4 ISA
bridge. The system manufacturer’s I/O Module,
which connects to the Intel Mobile Module, must
include a PIIX4 ISA bridge device. The PIIX4 ISA
bridge provides extensive power management
capabilities and is designed to support both the
430TX PCIset for current mobile Pentium
processors and the next Northbridge device for the
next generation of Intel mobile processors.

Architecture Overview
The Intel Mobile Module is a small, highly
integrated
assembly
containing
Pentium Processor with MMX technology
200/233MHz with internal/bus frequencies of
200/66 and 233/66 MHz and its immediate system-
level support. The module interfaces electrically to
its host system via a 3.3V PCI bus, a 3.3V memory
bus, 2.5V CPU interface signals, and the Intel
430TX PCIset system controller.

The Intel Mobile Module includes a second-level
cache of pipeline burst SRAM with capabilities to
burst read/write at 3-1-1-1 and back-to-back burst
reads at 3-1-1-1-1-1-1-1. The module supports up
to 64 MB of cacheable system memory (non-PCI
memory)

The Intel Mobile Module contains key features of
the Intel 430TX PCIset system controller. The
DRAM controller supports EDO at 3.3V with a
burst read at 5-2-2-2 (60ns) and SDRAM at 3.3V
with
a
burst
(66 MHz, CL=2). The system controller provides a
PCI CLKRUN# signal to control memory clock on
the PCI bus as well as the internal clock control
(also known as Chip Standby or Gated Clock). The
SDRAM clock enables support and self refresh of
EDO or SDRAM during Suspend mode and is fully
compatible SMRAM (C_SMRAM) and Extended
SMRAM
(E_SMRAM)

The processor core voltage regulation supports
input voltages from 5V to 20V (+5 percent)
enabling an at or above 85 percent peak
efficiencies and de-couples processor voltage
requirements from the system.
The Intel Mobile Module incorporates Active
thermal feedback (ATF) sensing, ACPI Rev 1.0
compliant by including an internal A/D - digital
signaling (SMBUS) across the module interface
and a programmable trip point interrupt or poll
mode for reading temperature.
