XCPS016 – DECEMBER 1997
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 kW resistor.

system block diagram
A simplified system block diagram using the PCI1220 is provided below. The PCI950 IRQ deseralizer and the PCI930 zoomed video (ZV) switch are optional functions that can be used when the system requires that capability.
The PCI interface includes all address/data and control signals for PCI protocol. The 68-pin PC Card interface includes all address/data and control signals for CardBus and 16-bit (R2) protocols. When zoomed video (ZV) is enabled (in 16-bit PC Card mode) 23 of the 68 signals are redefined to support the ZV protocol.
The interrupt interface includes terminals for parallel PCI, parallel ISA, and serialized PCI and ISA signaling. Other miscellaneous system interface terminals are available on the PCI1220 that include:

3–Line Power Switch Clock. Information on the DATA line is sampled at the rising edge of CLOCK. CLOCK defaults to an input, but can be changed to a PCI1220 output by using the P2CCLK bit in the System Control Register. The TPS2206 defines the maximum frequency of this signal to be 2MHz.
If a system design defines this terminal an output, then this terminal requires an external pullup resister. The frequency of the PCI1220 output CLOCK is derived from dividing the PCI CLK by 36.
3–Line Power Switch Data. DATA is used to serially communicate socket power control information to the power switch.
3–Line Power Switch Latch. LATCH is asserted by the PCI1220 to indicate to the PC Card power switch that the data on the DATA line is valid. When a pulldown resitor is implemented on this terminal, the MFUNC4 and MFUNC1 terminals provide the serial EEPROM SCL and SDA interface.
PCI bus clock. PCLK provides timing for all transactions on the PCI bus. All PCI signals are sampled at the rising edge of PCLK.

PCI system error. SERR is an output that is pulsed from the PCI1220 when enabled through the command register indicating a system error has occurred. The PCI1220 need not be the target of the PCI cycle to assert this signal. When SERR address parity error has occurred on a CardBus interface.

FUNCTION
Multifunction Terminal 5. MFUNC5 can be configured as PC/PCI DMA Grant, GPI4, GPO4, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE
Multifunction Terminal 4. MFUNC4 can be configured as PCI LOCK, GPI3, GPO3, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE
Serial Clock (SCL). When the serial bus mode is implemented by pulling the LATCH terminal low, the MFUNC4 terminal provides the SCL signaling. The two pin serial interface is used to load the subsystem identification and other register defaults from an EEPROM after a PCI reset.
Multifunction Terminal 3. MFUNC3 can be configured as a parallel IRQ or the serialized interrupt signal IRQSER.
Multifunction Terminal 2. MFUNC2 can be configured as PC/PCI DMA Request, GPI2, GPO2, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE
Multifunction Terminal 1. MFUNC1 can be configured as parallel PCI interrupt INTB, GPI1, GPO1, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE
Serial Data (SDA). When the serial bus mode is implemented by pulling the LATCH terminal low, the MFUNC1 terminal provides the SDA signaling. The two pin serial interface is used to load the subsystem identification and other register defaults from an EEPROM after a PCI reset.
Multifunction Terminal 0. MFUNC0 can be configured as parallel PCI interrupt INTA, GPI0, GPO0, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE
Ring Indicate Output and Power Management Event. When configured by the PME
, this terminal is used to indicate that a power management event is occuring. If the ring indicate
function is enabled by the Suspend. SUSPEND is used to protect the internal registers from clearing when the PRST signal is
asserted.
Speaker output. SPKROUT is the output to the host system that can carry SPKR or CAUDIO through the PCI1220 from the PC Card interface. SPKROUT is driven as the exclusive-OR combination of card SPKR
//CAUDIO inputs.
