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 YentaTM PCI to PCMCIA CardBus Bridge register compatible 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 two PC Card or CardBus slots 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 Supports parallel or serial interface for socket power control including devices from O2Micro (OZ2206), Micrel and TI Zoomed Video Support; Zoomed Video Buffer Enable Pins D3cold state PME# wakeup support 3.3Vaux Power Support Subsystem Vendor ID support, with auto lock bit LED Activity Pins
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 new development of many new functions and applications. The OZ6933 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 OZ6933 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 OZ6933 dual PCMCIA socket supports two 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 OZ6933 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 OZ6933 supports dynamic PC Card hot insertion and removal, with auto configuration capabilities. The OZ6933 is fully compliant with the 33Mhz PCI Bus specification, v2.2. It supports a master device with internal CardBus direct data transfer. The OZ6933 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 OZ6933 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 OZ6933 is a PCMCIA R2/CardBus controller, providing the most advanced design flexibility for PC Cards that interface with advanced notebook designs.
