The PCI1031 provides a set of features that makes it ideal for bridging between PCI and PC Cards in both notebook and desktop computers. The 1995 PC Card standard retains the 16-bit PC Card specification defined in PCMCIA release 2.1 and is capable of full 16-bit data transfers at 33 MHz. The PCI1031 supports any combination of 16-bit and PC Cards in its two sockets, powered at 3.3 V or 5 V, as required. The PCI1031 is compliant with the PCI local bus specification revision 2.1, and its PCI interface can act as either a PCI master device or a PCI slave device. The PCI bus mastering is initiated during 16-bit PC Card DMA transfers. All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI1031 is register compatible with the Intel 82365SL-DF PC Card interface controller. The PCI1031 internal datapath logic allows the host to access 8- and 16-bit cards using full 32-bit PCI cycles for maximum performance. Independent 32-bit write buffers allow fast-posted writes to improve system-bus utilization. An advanced CMOS process is used to achieve low system-power consumption while operating at PCI clock rates up to 33 MHz. Low-power modes allow the host power-management system to further reduce power consumption. All unused PCI1031 pins should be pulled high by a 43-kΩ resistor. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PCI1031 PCI-TO-PC CARD16 CONTROLLER UNIT SCPS008B – FEBRUARY 1996 – REVISED DECEMBER 1997 system block diagram – 16-bit PC Card interface A simplified system block diagram using the PCI1031 is provided below. The PCI950 IRQ deseralizer and the PCI930 zoomed video (ZV) switch are optional functions that can be used when the system requires that capability. The PCI interface includes all address/data and control signals for PCI protocol. The 68-pin PC Card interface includes all address/data and control signals for 16-bit (R2) protocols. When zoomed video (ZV) is enabled (in 16-bit PC Card mode) 23 of the 68 signals are redefined to support the ZV protocol. The interrupt interface includes terminals for parallel PCI, parallel ISA, and serialized PCI and ISA signaling. Other miscellaneous system interface terminals are available on the PCI1031 that include: D D D Multifunction IRQ terminals SUSPEND, RI_OUT (power management control signals) SPKROUT.
