Description

O2Micro's OZ992 Smart ACPI/SCI (System Control Interrupt) General Purpose Input/Output unit allows OEMs to transform their legacy systems to ACPI compliant systems by supporting up to 16 extra SCI inputs. Regular core logic chipsets, such as the Intel 430TX/BX and ACPI compliant embedded controllers have limited allowance for the GPIO or SCI input signals for the system. The OZ992 provides a bridge between the chipsets and the rest of the system to allow system designers a cost-effective way to improvise for such a deficiency.

OZ992 provides up to 20 GPIO signals in regular SMB slave mode. In addition, the OZ992 allows up to 16 System Control Interrupt (SCI) input transitions to be written to the system's embedded controller in master mode. The OZ992 provides the perfect solution for leading notebook vendors to stay ahead of the competition.

The OZ992 is an SMBus 1.0 compliant ACPI GPIO with 16 Programmable General Purpose I/Os pins flexible for a variety of functions such as programmable inputs/outputs, SMB/SMI interrupt service, power-saving, modularized hardware ID, and Auto LED Flash (ALF) status display. OZ992's other features include hardware-driven speaker alarm output.

As a Pentium and x86-based system compatible device, the OZ992 Smart ACPI GPIO is a highly costeffective and practical solution for today's notebook and palmtop computers, pen-based data systems, personal digital assistants, and portable datacollection terminals.
