DESCRIPTION
The TI PCI1420, the industry’s first 208-pin controller to meet the PCI Bus Power Management Interface
Specification for PCI to CardBus Bridges, is a high-performance PCI-to-CardBus controller that supports two
independent card sockets compliant with the 1997 PC Card Standard. The PCI1420 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 PCI1420 supports any
combination of 16-bit and CardBus PC Cards in the two sockets, powered at 5 V or 3.3 V, as required.
The PCI1420 is compliant with the PCI Local Bus Specification, 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. The PCI1420 is also compliant with the latest PCI Bus Power
Management Interface Specification.
All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI1420
is register compatible with the Intel 82365SL-DF and 82365SL ExCA controllers. The PCI1420 internal data path
logic allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance.
Independent buffering and a pipeline architecture provide an unsurpassed performance level with sustained
bursting. The PCI1420 can also be programmed to accept fast posted writes to improve system-bus utilization.
