Product Summary
The OZ9910GN is a 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 OZ9910GN 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.
