1 Introduction
The Texas Instruments PCI6515 controller is an integrated single-socket PC Card controller and Smart Card
controller. This high-performance integrated solution provides the latest in PC Card and Smart Card technology.
1.1
Controller Functional Description
1.1.1
PCI6515 Controller
The PCI6515 controller is a two-function PCI controller compliant with
PCI Local Bus Specification
, Revision 2.3.
Function 0 provides an independent PC Card socket controllers compliant with the
PC Card Standard
(Release 8.1).
The PCI6515 controller provides features that make it the best choice for bridging between the PCI bus and PC Cards,
and supports 16-bit, CardBus, or USB custom card interface PC Cards, powered at 5 V or 3.3 V, as required.
All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI6515
controller is register compatible with the Intel 82365SL-DF ExCA controller. The PCI6515 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
PCI6515 controller can be programmed to accept posted writes to improve bus utilization.
Function 5 of the PCI6515 controller is a PCI-based Smart Card controller used for communication with Smart Cards
inserted in PC Card adapters or the dedicated Smart Card socket. Utilizing Smart Card technology from Gemplus,
this function provides compatibility with many different types of Smart Cards.
1.1.2
Multifunctional Terminals
Various implementation-specific functions and general-purpose inputs and outputs are provided through eight
multifunction terminals. These terminals present a system with options in PCI LOCK, serial and parallel interrupts,
PC Card activity indicator LEDs, and other platform-specific signals. PCI complaint general-purpose events may be
programmed and controlled through the multifunction terminals, and an ACPI-compliant programming interface is
included for the general-purpose inputs and outputs.
1.1.3
PCI Bus Power Management
The PCI6515 controller is compliant with the latest
PCI Bus Power Management Specification
, and provides several
low-power modes, which enable the host power system to further reduce power consumption.
1.1.4
Power Switch Interface
The PCI6515 controller also has a three-pin serial interface compatible with the Texas Instruments TPS2228
(default), TPS2226, TPS2224, TPS2223A, and TPS2220 power switches. All five power switches provide power to
the CardBus socket on the PCI6515 controller. The power to the dedicated Smart Card socket is controlled through
a separate power control pin that can be used to control an external 5-V power switch or it may be configured to source
power through BVPP of a dual socket PCMCIA power switch.
1.2
Features
The PCI6515 controller supports the following features:
PC Card Standard
8.1 compliant
PCI Bus Power Management Interface Specification
1.1 compliant
