description

The TI PCI1220 is a high-performance PCI-to-PC Card controller that supports two independent PC Card sockets compliant with the 1995 PC Card Standard. The PCI1220 provides a rich feature set that makes it the best choice 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 defines the new 32-bit PC Card, CardBus, capable of full 32-bit data transfers at 33 MHz. The PCI1220 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 PCI1220 is compliant with the PCI Local Bus Specification 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 direct memory access (DMA) transfers or CardBus PC Card bridging transactions. The PCI1220 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 PCI1220 is register compatible with the Intel 82365SL-DF ExCA controller. The PCI1220 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 PCI1220 can also be programmed to accept fast posted writes to improve system-bus utilization.

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 are designed into the PCI1220, such as socket activity light-emitting diode (LED) outputs, and are discussed in detail throughout the design specification.

An advanced complementary metal-oxide semiconductor (CMOS) process is used to achieve low system-power consumption while operating at PCI clock rates up to 33 MHz. Several low-power modes enable the host power management system to further reduce power consumption.

Unused PCI1220 inputs must be pulled up using a 43 k resistor.
