Intelligent Manager
Smart ACPI GPIO/SCI
GENERAL 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 cost-
effective and practical solution for today’s notebook
and palmtop computers, pen-based data systems,
personal digital assistants, and portable data-
collection terminals.
