The PCI8402 controller is a four-function PCI controller compliant with
PCI Local Bus Specification
, It is 216 ball
PBGA package.
Function 0 is a dummy PC Card controller function. The PC Card socket is non-functional and the pins associated
with the PC card socket may be left unconnected. The function is required for device enumeration and is provided
for BIOS compatibility with existing devices. The PC Card function may be hidden from the OS by the BIOS.
Function 1 of the PCI8402 controller is compatible with IEEE Std 1394a-2000 and the latest
1394 Open Host
Controller Interface Specification
. The chip provides the IEEE1394 link and 1-port PHY function and is compatible
with data rates of 100, 200, and 400 Mbits per second. Deep FIFOs are provided to buffer 1394 data and
accommodate large host bus latencies. The PCI8402 controller provides physical write posting and a highly tuned
physical data path for SBP-2 performance.
Function 2 of the PCI8402 controller is a PCI-based Flash Media controller that supports Memory Stick, Memory
Stick-Pro, SmartMedia, xD, SD, and MMC cards. This function controls communication with these Flash Media
cards through a dedicated Flash Media socket. In addition, this function includes DMA capabilities for improved
Flash Media performance.
Function 3 of the PCI8402 controller is a PCI-based SD host controller that supports MMC, SD, and SDIO cards.
This function controls communication with these Flash Media cards through a dedicated Flash Media socket. In
addition, this function is compliant with the
SD Host Controller Standard Specification
and includes both DMA
capabilities and support for SD suspend/resume.
