description

The TI PCI1031 is a high-performance PCI-to-PC Card16 controller that supports two independent PC Card

sockets compliant with the1995 PC Card standard. 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-k

Ω resistor.
