Product Summary

The OZ9928SN is an Intelligent Manager Smart ACPI GPIO/SCI. It 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 OZ9928SN 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. The OZ9928SN provides the perfect solution for leading notebook vendors to stay ahead of the competition. It provides up to 20 GPIO signals in regular SMB slave mode. In addition, the OZ9928SN allows up to 16 System Control Interrupt (SCI) input transitions to be written to the system’s embedded controller in master mode.
