***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

**82497/492   Cache Controller / Cache RAM (for P54 Pentium)    <Nov94
***Notes:
Date source: 1995_Intel_Pentium_Processors_and_Related_Components.pdf

The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in the configurations section  and below have been sourced
from the second.

"Although the 82497 Cache Controller  is part of the Pentium processor
(735\90, 815\100, 1000\120, 1110\133) CPU-Cache Chip Set and the 82496
Cache  Controller is part  of the  Pentium Processor  (510\60, 567\66)
Chip  Set, the  two parts  are functionally  identical except  for the
differences noted in this section." - p491

Aside  from some  minor  differences in  pin  configuration, the  main
difference is the direct support  for 3.3V processors. This chipset is
still a 5V part. The cache operates at bus speed, max 66MHz.


This  chip was  used on  the Pentium  90MHz CPU  complexes of  Intel's
Xpress  platform.   Specifically  the BXCPUPENT90  (Single  90MHz,  16
82492s). Also found on IBM 9595/Server 500 Pentium 90MHz complexes.
