1.3.5 PC Card Interface Controller: ENE CB1410

The ENE CB1410 is a high-performance PCI-to-PC Card controller that supports a single PC Card socket compliant with the 1997 PC Card Standard. The ENE CB1410 provides features that make it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The 1997 PC Card Standard retains the 16-bit PC Card specification defined in PCI Local Bus Specification and defines the new 32-bit PC Card, CardBus, capable

of full 32-bit data transfers at 33 MHz. The ENE CB1410 supports both 16-bit and CardBus PC Cards, powered at 5

V or 3.3 V, as required.

Secret

The ENE CB1410 is compliant with the PCI Local Bus Spe ification, 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 or

CardBus PC Card bridging transactions.MiTacThe ENE CB1410 is also compliant with the latest PCI Bus Power

Management Interface Specification and PCI Bus Power Management Interface Specification for PCI to CardBus

Bridges.Confidential bus utilization.

All card signals are internally buffered to allow hot insertion and removal without external buffering. The ENE CB1410 internal data path logic allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for

maximum performance. Indepe buffering and a pipeline architecture provide an unsurpassed performance level

with sustained bursting. The ENE CB1410 can also be programmed to accept fast posted writes to improve system-

Multiple system-interrupt signaling options are provided, including: parallel PCI, parallel ISA, serialized ISA, and serialized PCI. Furthermore, general-purpose inputs and outputs are provided for the board designer to implement sideband functions. Many other features designed into the ENE CB1410, such as socket activity light-emitting diode (LED) outputs, are discussed in detail throughout the design specification.
