OZ6912
Single-Slot ACPI CardBus Controller
FEATURES
specification as defined by PCMCIA release 2.1. CardBus
is intended to support “temporal” add-in functions on PC
Cards, such as Memory cards, Network interfaces,
FAX/Modems and other wireless communication cards, etc.
The high performance and capability of the CardBus
interface will enable the new development of many new
functions and applications.

ACPI-PCI Bus Power Management Interface
Specification Rev 1.1 Compliant
Supports OnNow LAN wakeup, OnNow Ring Indicate,
PCI CLKRUN#, PME#, and CardBus CCLKRUN#
Compliant with PCI specification v2.2, 2000 PC Card
Standard 7.1
Yenta™ PCI to PCMCIA CardBus Bridge register
compatible
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 OnNow Power Management includes D3cold
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.
ExCA (Exchangeable Card Architecture) compatible
registers mappable in memory and I/O space
IntelTM 82365SL PCIC Register Compatible
Supports PCMCIA_ATA Specification
Supports 5V/3.3V PC Cards and 3.3V CardBus cards
Supports single PC Card or CardBus slot with hot
insertion and removal
Supports multiple FIFOs for PCI/CardBus data transfer
Supports Direct Memory Access for PC/PCI and
PCI/Way on PC Card socket
Programmable interrupt protocol: PCI, PCI+ISA,
PCI/Way, or PC/PCI interrupt signaling modes
Win’98 IRQ and PC-98/99 compliant
Supports parallel or serial interface for socket power
control including devices from Micrel and TI

The OZ6912 single PCMCIA socket supports a mix and
match 3.3V/5V 8/16-bit PC Card R2 card or 32-bit CardBus
R3 card. 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 a stand alone device, which
means that it does not require 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.

ORDERING INFORMATION
OZ6912T - 144pin LQFP
The OZ6912 is fully compliant with the 33Mhz PCI Bus
specification, v2.2. It supports a master device with internal
CardBus direct data transfer. The OZ6912 implements a
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.
OZ6912B - 144pin Mini-BGA
GENERAL DESCRIPTION
The OZ6912 is an ACPI and PC98/99 Logo Certified, high
performance, single slot PC Card controller with
a
synchronous 32-bit bus master/target PCI interface. This
PC Card to PCI bridge host controller is compliant with the
2000 PC Card Standard. This standard incorporates the
new 32-bit CardBus while retaining the 16-bit PC Card
The OZ6912 is a PCMCIA R2/CardBus controller, providing
the most advanced design flexibility for PC Cards that
interface with advanced notebook designs.
