description
The Texas Instruments PCI1450 is a high-performance PC Card controller with a 32-bit PCI interface. The device supports two independent PC Card sockets compliant with the 1997 PC Card Standard and the PCI Bus Interface Specification for PCI-to-CardBus Bridges. The PCI1450 provides a rich feature set which makes it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The 1995 and 1997 PC Card Standards retain 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 PCI1450 supports any combination of 16-bit and CardBus PC Cards in the two sockets, powered at 5 Vdc or 3.3 Vdc as required. The PCI1450 is compliant with the latest PCI Bus Power Management Specification. It is also 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, or CardBus PC Card bridging transactions. All card signals are internally buffered to allow hot insertion and removal. The PCI1450 is register compatible with the Intel 82365SL-DF ExCA controller. The PCI1450 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 PCI1450 can also be programmed to accept fast posted writes to improve system bus utilization. The PCI1450 provides an internally buffered zoom video (ZV) path. This reduces the design effort of PC board manufacturers to add a ZV compatible solution and guarantees compliance with the CardBus loading specifications. Multiple system interrupt signaling options are provided: Serial ISA/Serial PCI, Serial ISA/Parallel PCI, Parallel ISA/Parallel PCI, and PCI Only interrupts. Furthermore, general-purpose inputs and outputs (GPIOs) are provided for the board designer to implement sideband functions. Many other features are designed into the PCI1450 such as socket activity LED outputs, and are discussed in detail throughout the design specification. An advanced complementary metal-oxide semiconductor (CMOS) process achieves low system power consumption while operating at PCI clock rates up to 33 MHz. Several low-power modes allow the host power management system to further reduce power consumption. Unused PCI1450 inputs must be pulled up using a 43 kW resistor. use of symbols in this document Throughout this data sheet the overbar symbol denotes an active-low signal. For example: FRAME denotes that this is an active-low signal.
