Intelligent Manager
Smart PMU/GPIO
GENERAL DESCRIPTION
O2Micro’s OZ990 Smart PMU/GPIO (Power
Management Unit/General Purpose Input Output) unit
allows the implementation of Green PC Desktop
Chipsets in notebook designs at considerably lower
cost than conventional methods while closing the
technology gap between desktop and notebook
computers by offering an extensive number of
powerful power management and general purpose I/O
features. With the OZ990 stand-alone PMU capability,
the ability to provide the One-Shot Design for
PMU/BIOS practically eliminates the need to redesign
PMUs to match the ever-changing core logic chipsets.
The OZ990 provides the perfect solution for leading
notebook vendors to stay ahead of the competition.
The OZ990 is an SMBus 1.0 compliant device with 4
Power Control and 16 Programmable General
Purpose I/Os pins flexible for a variety of functions
such as Power Control with sequencing,
programmable inputs/outputs, SMB/SMI interrupt
service,
power-saving,
Suspend/Wakeup,
modularized hardware ID, and Auto LED Flash (ALF)
status display. Other features include hardware-driven
speaker alarm output and Suspend/Wakeup button.
As a Pentium class and x86-based system compatible
device, the OZ990 is a highly cost-effective and
practical solution for today’s notebook and palmtop
computers, pen-based data systems, personal digital
assistants, and portable data-collection terminals.
