**WD8110 System controller for 80386DX/486 <11/30/93
***Notes:...
***Info:
1.0 INTRODUCTION
The WD8110/LV System Controllers are designed to provide a high
performance, single chip system controller supporting all 80486SX,
80486DX. 80386SX and 80386DX CPUs in AT bus based Desktop/
Laptop/Notebook/Pen-based systems.
1.1 DOCUMENT SCOPE
This document describes the function and operation of the WD8110/LV
System Controller devices. It includes the description of external
logic necessary for efficient use of these devices. The WD8110/LV is
also referred to in this document as the System Controller.
1.3 WD8110/LV POWER MANAGEMENT
Power Management Control (PMC) is used for powering down the processor
or peripherals and includes processor stop clock, slow clock, auto-
matic processor clock speed switching modes and CAS before RAS slow
refresh. Suspend and resume is supported and low power DRAM is
refreshed while the processor and other power consuming devices are
turned off. The power drain for the core logic and VGA controller is
less than 2 mA in this mode. Power and clock speed may be controlled
by the Keyboard Controller. transparently to the 80386 or 80486.
The System Activity Monitor (SAM) is a transparent feature that
replaces the functions previously performed by software. It senses
when the system has been idle for a previously programmed period at
time and determines a clean break point in which to perform power down
activities such as suspend.
The system controller also supports System Management Interrupt (SMI)
with complete I/O trapping of up to six separate I/O ranges. Each
range has an independent timer which can generate an SMI after a
programmed period of time during which there was no I/0 access to that
range.
1.3.1 Desktop Applications
The WD8110/LV provides a high performance solution with a flexible
memory controller architecture. including support for five banks of
memory. The WD8110/LV can fully support an external look-aside cache
or a combination primary and secondary cache. This feature makes it
particularly suitable for use with cached microprocessors where it
maintains cache coherency via its built-in bus snooping capability. In
addition. the WD8110/LV supports Video Local Bus Interface (VLBI) for
enhanced graphics performance.
The built-in power management features of the WD8110/LV allows a high
performance yet power efficient desk top solution.
1.3.2 Portable Applications
The WD8110LV is an ideal choice because of its advanced power
management features and power saving 3.3 volt operation, which
delivers long battery life in a compact footprint. This makes it a
perfect choice for laptop, notebook, pen-based and palmtop computers.
The five bank memory controller on the WD8110LV provides the user with
great flexibility in the selection of 3.3 volt DRAMs to meet system
memory requirements in low voltage platforms. The WD8110LV memory
controller supports JEDEC standard 3.3 volt DRAM in various
configurations, including the JEIDA standard 88-pin DRAM card.
The WD8ll0/LV can be paired with the appropriate support devices from
Western Digital to deliver the most efficient solution for any
platform. For 5 volt desktop or portable platforms, the WD8l10/LV can
be used with the WD76C20 Peripheral Controller and the WD76C30 I/O
Controller. The WD8110 may also be used with the WD7615 Buffer Manager
device and a generic Super I/O chip to implement a low cost desktop
platform. For 3.3 volt applications, the WD8110LV can be used with the
WD76C20ALV and WD76C30ALV, both of which incorporate level translators
(split rail operation). For subnotebook and palmtop type applications,
WD7625LV buffer manager and WD8120LV Super I/O can be added to the
WD8110LV based solution to achieve a very compact footprint.
The WD8110/LV is a fifth generation system controller device derived
from core chips with proven compatibility and design maturity in
several of the industry's leading desktop and portable platforms.
Designed with the state of the art 0.9 micron high performance CMOS
process. the WD8110/LV family maintains architectural compatibility
with Western Digital's WD7600 and WD7855 systems logic chip sets while
incorporating many additional performance enhancements.
