This PC Card to PCI bridge host controller is compliant with the 04/25/00 Copyright 2000 by O2Micro 1998 PC Card Standard. This standard incorporates the new 32-bit CardBus while retaining the 16-bit PC Card 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 development of many new functions and applications. The OZ6812 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. The device also provides a power-down mode to allow host software to reduce power consumption further by stopping internal clock distribution as well as the PC Card socket clock. In addition, an advanced CMOS process is utilized to minimize system power consumption. The OZ6812 single PCMCIA socket supports 3.3V/5V 8/16bit 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 1998 PC Card Standard CardBus specification. The OZ6812 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 OZ6812 supports dynamic PC Card hot insertion and removal, with auto configuration capabilities. The OZ6812 is fully compliant with the 33Mhz PCI Bus specification, V2.2. It supports a master device with internal CardBus direct data transfer. The OZ6812 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 (composed of 16 double words) permits the OZ6812 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.

A Bus transaction consists of an address phase followed by one or more data phases. C/BE[3:0]# PCI Bus Command / Byte Enable: The command signaling and byte enables are multiplexed on the same pins. During the address phase of a transaction, C/BE[3:0]# are interpreted as the bus commands. During the data phase, C/BE[3:0]# are interpreted as byte enables. The byte enables are to be valid for the entirety of each data phase, and they indicate which bytes in the 32-bit data path are to carry meaningful data for the current data phase. Cycle Frame: This input indicates to the OZ6812 that a bus transaction is beginning. While FRAME# is asserted, data transfers continue. When FRAME# is de-asserted, the transaction is in its final phase. Initiator Ready: This input indicates the initiating agent’s ability to complete the current data phase of the transaction. IRDY# is used in conjunction with TRDY#. Target Ready: This output indicates target Agent's the OZ6812’s ability to complete the current data phase of the transaction. TRDY# is used in conjunction with IRDY#. Stop: This output indicates the current target is requesting the master to stop the current transaction. Initialization Device Select: This input is used as a chip select during configuration read and write transactions. This is a point-to-point signal. IDSEL can be used as a chip select during configuration read and write transactions. Device Select: This output is driven active LOW when the PCI address is recognized as supported, thereby acting as the target for the current PCI cycle. The Target must respond before timeout occurs or the cycle will terminate. Parity Error: The output is driven active LOW when a data parity error is detected during a write phase. System Error: This output is driven active LOW to indicate an address parity error.

During the address phase, PAR is valid after one clock. With data phases, PAR is stable one clock after a write or read transaction. PCI Clock: This input provides timing for all transactions on the PCI bus to and from the OZ6812. All PCI bus signals, except RST#, are sampled and driven on the rising edge of PCI_CLK. This input can be operated at frequencies from 0 to 33 MHz. Device Reset: This input is used to initialize all registers and internal logic to their reset states and place most OZ6812 pins in a HIGHimpedance state. Grant: This signal indicates that access to the bus has been granted. Request: This signal indicates to the arbiter that the OZ6812 requests use of the bus.

Usually, a PME occurs during a request to change from a power saving state to the fully operational state. Speaker Output: This output can be used to support PC Card audio output. See O2 Mode E Register (Index + 3Eh), bit 1. Multifunction Terminal [6:0]: See PCI Multifunction MUX Register (Offset:08h). Suspend: This signal is used to protect the internal registers from clearing when the PCI RST# signal is asserted. When low, this signal is used to mask the PCI RESET during suspend. This pin can be used during suspend to prevent controller reset.

DIMENSIONING AND TOLERANCING PER ASME Y14.5M-1994. 2. "e" REPRESENTS THE SOLDER BALL GRID PITCH. 3. "N" REPRESENTS THE MAXIMUM NUMBER OF SOLDER BALLS FOR MATRIX SIZE M1 AND M2. 4. DIMENSION "b" IS MEASURED AT THE MAXIMUM SOLDER BALL DIAMETER AFTER REFLOW AND PARALLEL TO PRIMARY DATUM Z, THE ORIGINAL SOLDER BALL DIAMETER IS 0.45 mm. 5. PRIMARY DATUM Z AND SEATING PLANE ARE DEFINED BY THE SPHERICAL CROWNS OF THE SOLDER BALLS. 6. A1 CORNER MUST BE IDENTIFIED BY INK MARK, METALLIZED MARKINGS, IDENTATION OR OTHER FEATURE OF PACKAGE BODY, LID OR INTEGRAL HEATSLUG, ON THE TOP SURFACE OF THE PACKAGE. 7. SOLDER BALL DEPOPULATION IS ALLOWED. DEPOPULATION IS THE OMISSION OF BALLS FROM A FULL MATRIX (M1 OR M2). 8. BALL PAD A1 CORNER INDICATOR (NC) SOLDER BALL OZ6812-SF-1.5 Page 13
