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.
