Hardware Functional Overview 
 
The OZ6912 CardBus controller is compliant with the latest ACPI-PCI Bus Power 
Management interface Specification. It supports all four power states and the PME# function 
for maximum power savings and ACPI compliance. Additional compliance to On Now Power 
Management includes D3 cold state support, paving the way for low sleep state power 
consumption and minimized resume times. To allow host software to reduce power 
consumption further, the OZ6912 provides a power-down mode in which internal clock 
distribution and the PC Card socket clocks are stopped. An advanced CMOS process is also 
used to minimize system power consumption. 
 
The OZ6912 single PCMCIA socket supports the 3.3V/5V 8/16-bit PC Card R2 cards or 32-
bit CardBus R3 cards. The R2 card support is compatible with the Intel 82365SL PCIC 
controller, and the R3 card support is fully compliant with the 2000 PC Card Standard 
CardBus specification. The OZ6912 is an additional buffer chip for the PC Card socket 
interface. In addition, the OZ6912 supports dynamic PC Card hot insertion and removal, with 
auto configuration capabilities. 
 
The OZ6912 is fully complains with the 33Mhz PCI Bus specification, v2.2. It supports a 
master device with internal CardBus direct data transfer. The OZ6912 implements FIFO data 
buffer architecture between the PCI bus and CardBus socket interface to enhance data 
transfers to CardBus Devices. The bi-directional FIFO buffer permits the OZ6912 to accept 
data from a target bus (PCI or CardBus interface) while simultaneously transferring data. This 
architecture not only speeds up data transfers but also prevents system deadlocks. 
 
The OZ6912 is a PCMCIA R2/CardBus controller, providing the most advanced design 
flexibility for PC Cards that interface with advanced notebook designs.
