System Architecture Overview
Intel 852GM GMCH System Architecture
The Intel 852GM GMCH component provides the processor interface, DDR SDRAM interface, display
interface, and Hub Interface in an Intel 852GM chipset platform. The Intel 852GM GMCH is optimized
for the Mobile Intel Pentium 4 Processor-M, Mobile Intel Celeron processor and Intel Celeron M
processor. It supports a single channel of DDR SDRAM memory. Intel 852GM Chipset contains
advanced power management logic. The Intel 852GM Chipset platform supports the fourth generation
mobile I/O Controller Hub to provide the features required by a mobile platform.
The Intel 852GM GMCH is in a 732-pin Micro-FCBGA package and contains the following
functionality:
Supports single Intel processor configurations at 400-MHz or 3 GB/s
1.2-1.30-V AGTL+ host bus supporting 32-bit host bus addressing with Enhanced Intel
SpeedStep^® technology (Intel Celeron M processor and Intel Celeron Processor do not support
Enhanced Intel SpeedStep Technology).
System Memory supports 200/266-MHz (SSTL_2) DDR DRAM
Up to 1 GB (with 256-Mb technology and two SO-DIMMs) of PC1600/2100 DDR SDRAM
without ECC
Integrated graphics capabilities, including 3D rendering acceleration and 2D hardware
acceleration
Integrated 350-MHz, 24-bit RAMDAC with pixel resolution up to 1600x1200 at 85-Hz and up to
1920x1440 @ 60 Hz
One Dedicated Dual Channel LFP LVDS interface with frequency range of 25 MHz to 112 MHz
(single channel/dual channel) for support up to SXGA+ (1400x1050 @ 60 Hz) panel resolutions
with maximum pixel depth of 18-bpp
Integrated PWM (Pulse Width Modulation) interface for LFP backlight inverter control for panel
brightness
One 165-MHz, 12-bit, DVO interface for TV-out encoder and DVI (LVDS transmitter and TMDS
transmitter) support
I2C and DDC channels supported
Dual Pipe Independent Display with Tri-view support through LFP, DVO, and CRT
Deeper Sleep state support
Distributed arbitration for highly concurrent operation
