***Info & Features:
M1561 Overview

128-bit Super-Socket7  North Bridge for AMD-K6-III  with integrated 3D
and Video Highest-performance game playing in a single integrated chip

The M1561 integrates the following functionalities in a Unified Memory
Architecture PC:

o   3-D Graphics
o   2-D Windows Acceleration
o   VGA Display Controller
o   SDRAM Memory Controller
o   PCI Bus Interface

M1561  supports the  66/100/1XX MHz  Socket 7  Front Side  Bus.  It is
System Memory  Management (SMM)  and Advanced Configuration  and Power
Interface Specification (ACPI) compliant.

M1561 uses  66/100/1XX MHz SDRAM with LVTLL  input/output signals. The
chip supports up to four memory DIMMs.

Power supplies are 2.5V  for the core and 3.3V for most  of the I/O. A
5V  reference is  needed for  the  5V tolerant  PCI inputs.  Reference
voltages for ArtX and ArtX+ are  also needed.The part is packaged in a
35x35mm 492 ball Thermally Enhanced Ball Grid Array (T 2 BGA) package.

North Bridge Features
o   128-bit Data Streaming architecture for highest performance 
    SMA/UMA
o   PC99 compliant
o   100/66MHz CPU Front Side Bus, 1XXMHz ready
o   Standard PC-100/66 SDRAM (up to 1 GB) PC-1XX ready
o   33 MHz PCI 2.2 compliant I/O bus
o   ACPI power management
o   Compatible with single-chip ALi M1535D and M1543 South Bridges

Display Controller
o   Up to 1600x1200 non-interlaced screen resolution
o   Hardware features:
    - Analog CRT monitor output
    - 32-bit full-color
    - Fully compliant VGA adapter
    - Downloadable RAMDAC, hardware cursor
o   VBE 3.0 support

Memory interface
o   128-bit PC100/PC66 SDRAM, PC-1XX Ready
o   Up to 2.1 Gbytes/second bandwidth

Drivers
o   Optimized driver for DirectX 7 with Direct3D, OpenGL ICD, HWMC 
o   and GDI acceleration on Windows 98 and Windows 2000
o   Dynamic memory allocation for texture
o   Drivers available for Windows 98, Windows 2000 and Windows NT 4.0

Packaging
o   492-BGA, 35x35mm
