3 Feature/Protocol Descriptions

The following sections give an overview of the PCI1510 controller. Figure 3−1 shows a simplified block diagram of

the controller. 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.

NOTE: The PC Card interface is 68 terminals for CardBus and 16-bit PC Cards. In ZV mode, 23 terminals are used for routing the ZV signals

to the VGA controller and audio subsystem.

Power Supply Sequencing

The controller contains 3.3-V I/O buffers with 5-V tolerance requiring an I/O power supply and an LDO-VR power

supply for core logic. The core power supply, which is always 2.5 V, can be supplied through the VR_PORT terminal

(when VR_EN is high) or from the integrated LDO-VR. The LDO-VR needs a 3.3-V power supply via the VCC

terminals. The clamping voltages (VCCCB and VCCP) can be either 3.3 V or 5 V, depending on the interface. The

following power-up and power-down sequences are recommended.

The power-up sequence is:

Assert GRST to the device to disable the outputs during power up. Output drivers must be powered up in

the high-impedance state to prevent high current levels through the clamp diodes to the 5-V clamping rails

(VCCCB and VCCP).

Apply 3.3-V power to VCC.

Apply the clamp voltage.

The power-down sequence is:

Assert GRST to the device to disable the outputs during power down. Output drivers must be powered down

in the high-impedance state to prevent high current levels through the clamp diodes to the 5-V clamping

rails (VCCCB and VCCP).
