description
The TI PCI1221 is a high-performance PCI-to-PC Card controller that supports two independent card sockets
compliant with the 1997 PC Card Standard. The PCI1221 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 1997 PC Card
Standard retains the 16-bit PC Card specification defined in PCMCIA Release 2.2 and defines the new 32-bit
PC Card, CardBus, capable of full 32-bit data transfers at 33 MHz. The PCI1221 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 PCI1221 is compliant with the PCI Local Bus Specification 2.2, and its PCI interface can act as either a PCI
master device or a PCI slave device. The PCI bus mastering is initiated during CardBus PC Card bridging
transactions. The PCI1221 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 PCI1221
is register compatible with the Intel 82365SL-DF ExCA controller. The PCI1221 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
PCI1221 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 designed into the PCI1221, such as socket activity
light-emitting diode (LED) outputs, 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 PCI1221 inputs must be pulled up using a 43k
W
-resistor.

system block diagram
A simplified block diagram of the PCI1221 is provided below. The PCI interface includes all address/data and
control signals for PCI protocol. The interrupt interface includes terminals for parallel PCI, parallel ISA, and
serialized PCI and ISA signaling. Miscellaneous system interface terminals include multifunction terminals:
SUSPEND, RI_OUT/PME (power management control signal), and SPKROUT.
