Key Features
- 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, 1998 PC Card Standard 7.0 Yenta™ PCI to PCMCIA CardBus Bridge register compatible ExCA (Exchangeable Card Architecture) compatible registers mappable in memory and I/O space TM Intel 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 Parallel or Serial interface for socket power control devices including Micrel and TI Zoomed Video Support Integrated PC 98/99 -Subsystem Vendor ID support, with auto lock bit LED Activity Pins 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.
